The jobs that automation, regulation and fashion erased — and which surviving profession absorbed them.
Every profession here replaced something. These are the trades that no longer exist — erased by a machine, a law, a material or a change in taste — and the surviving job that absorbed what they did.
Barred by church custom from shedding blood, monks and university physicians left bleeding, tooth-pulling and amputation to barbers, who already kept razors sharp. London's barbers and surgeons were legally united into one guild in 1540, before the surgeons — by then better educated and better paid — successfully petitioned to split off as their own Company of Surgeons in 1745, ending the trade's centuries-long tie to haircutting.
Before hospitals routinely offered surgery, traveling "cutters for the stone" moved town to town removing bladder stones in a few brutal, unanesthetized minutes, sometimes in front of a paying audience. The most famous, French monk Frère Jacques Beaulieu, performed more than 5,000 such operations between roughly 1690 and 1719; the trade faded as hospital-based, formally trained surgeons and eventually safer techniques took over the work.
British law allowed anatomists to legally dissect only the bodies of executed murderers — fewer than 100 a year — far short of what a growing number of anatomy schools needed, so "resurrection men" dug up fresh graves and sold corpses to medical schools instead. The trade ended only after Edinburgh's Burke and Hare murdered at least sixteen people to sell as specimens in 1828, prompting Britain's Anatomy Act of 1832, which legalized the donation of unclaimed bodies.
For centuries a physician diagnosed and prescribed while a separate apothecary compounded and sold the remedy, a division European guilds enforced strictly to protect both trades' income. England's 1704 Rose case let apothecaries prescribe as well as dispense, and over the following century they evolved into a distinctly British role — the general practitioner — that fused diagnosis and dispensing back into one person, roughly the shape primary care still takes today.
Barbers doubled as surgeons throughout medieval Europe, pulling teeth, setting bones, letting blood and cutting hair with the same set of tools, organized in England under the Company of Barber-Surgeons from 1540. University-trained physicians, humoral theorists who considered cutting flesh beneath their status, looked down on them as tradesmen. An Act of Parliament split the company in 1745, the surgeons breaking away to found what became the Royal College of Surgeons, finally separating the profession this page covers from the one it works alongside today.
Towns hit by recurring plague outbreaks hired physicians, sometimes with little formal training, specifically to treat the afflicted poor once established doctors fled; many wore the head-to-toe leather costume and beaked mask, stuffed with aromatic herbs, that French physician Charles de Lorme designed in 1619 to guard against 'bad air.' The role and its costume vanished once quarantine, sanitation and eventually germ theory brought epidemic plague under control in Europe.
Every sizable medieval monastery had an infirmarian — a monk or nun charged with the infirmary, its herb garden and its dying — one of the few roles in medieval Europe with recognized, transmitted nursing expertise. The dissolution of the monasteries in Protestant lands, completed in England between 1536 and 1541, abolished the role and left a nursing vacuum that lasted three centuries.
Before training schools, hospitals and families hired untrained women — often elderly, often desperate for work — to sit with, feed and lay out the sick. Charles Dickens's gin-drinking Sairey Gamp in Martin Chuzzlewit (1843–44) fixed the type in the public mind and became a recruiting argument for reform; training schools and Britain's 1919 Nurses Registration Act finally priced the watcher out of existence.
Breastfeeding other families' infants was for centuries one of the few paid caring trades open to women, regulated closely enough that Hammurabi's Code and later Paris's municipal wet-nurse bureaus set its terms. Safe pasteurized milk, rubber-nippled feeding bottles and commercial infant formula collapsed the trade in the early twentieth century; today's hospital milk banks are its distant, anonymous descendant.
Europe's original medicines tradesman — guild-trained, legally separated from physicians since Frederick II — was pulled apart by his own descendants. In England, apothecaries won the right to advise patients in the Rose Case of 1704 and drifted into general medical practice, becoming the ancestors of today's GPs, while chemists and druggists took the dispensing trade. Industrial drug manufacture finished the job: by around 1900 the compounding shopkeeper had become either a physician, a pharmacist or a factory.
Traveling medicine shows toured America and Europe selling secret-formula cure-alls — Kickapoo Indian Sagwa, Hamlin's Wizard Oil — with music, comedy and planted testimonials. Many tonics were mostly alcohol; some, like Mrs. Winslow's Soothing Syrup for teething infants, contained morphine. Muckraking journalism (Samuel Hopkins Adams's 1905 series The Great American Fraud) and the 1906 Pure Food and Drug Act's labeling rules killed the trade, and pharmacy's claim to scientific legitimacy was built partly on its corpse.
Because pharmacists had carbonation equipment and flavor syrups, the American drugstore became the home of the soda fountain, staffed by the soda jerk — named for the jerking motion of the tap handles. Pharmacists invented the drinks themselves: Charles Alderton created Dr Pepper in a Waco, Texas drugstore in 1885, John Pemberton launched Coca-Cola at Jacobs' Pharmacy in Atlanta in 1886, and Caleb Bradham mixed the first Pepsi in his New Bern pharmacy in 1893. Bottling, drive-ins and self-service retail ended the fountain era by the 1970s.
'Leech' is Old English for healer, and the horse-leech was the untrained, apprenticeship-taught doctor of pre-scientific English horses, treating lameness and colic with bleeding and folk remedies. London's veterinary college (1791) and the Royal College's 1844 charter protected the title 'veterinary surgeon', but lay practice itself stayed legal until the Veterinary Surgeons Act 1948 finally restricted animal treatment to registered vets.
Before prescription-only veterinary drug laws, druggists and traveling peddlers sold proprietary 'cattle powders', 'colic drenches' and 'horse balls' directly to farmers, with no diagnosis and no vet involved at all. Twentieth-century licensing acts that reserved treatment and prescribing for registered veterinarians closed off this entire unregulated retail trade.
Knackers collected sick, dying or worn-out livestock for slaughter and rendering, and in the absence of any veterinary alternative effectively decided which animals were beyond saving. As animal-welfare and veterinary-licensing law tightened through the 19th and 20th centuries, that diagnostic judgment was reserved to licensed veterinarians, leaving the knacker's trade as regulated carcass disposal alone.
Before 'psychiatrist' became standard English usage, doctors who treated the insane were called alienists — from the French aliéné, meaning someone alienated from their own mind and society. The Association of Medical Superintendents of American Institutions for the Insane, founded in 1844, only renamed itself the American Psychiatric Association in 1921, roughly tracking when the older term fell out of use.
A single physician often ran an entire custodial institution housing hundreds or thousands of patients, controlling admissions, discharge, staffing and daily routine with near-total authority. Deinstitutionalization from the 1960s onward, driven by antipsychotic drugs and shrinking public asylum budgets, dissolved most of these institutions and, with them, the role of running one.
Following Egas Moniz's original leucotomy, American neurologist Walter Freeman developed and toured the country performing a crude 'transorbital' version — driving an ice-pick-like instrument through the eye socket in minutes, often in outpatient settings without a surgeon present. Antipsychotic drugs, lawsuits and mounting evidence of permanent harm ended the practice almost entirely by the 1970s.
England's most elite legal order for centuries, serjeants-at-law held the exclusive right of audience before the Court of Common Pleas and wore a distinctive white coif; only a serjeant could become a judge of that court. The Judicature Acts of 1873–75 stripped away the order's monopoly, and the last surviving serjeant died in 1921, five decades after the order had already stopped admitting new members.
London's professional scriveners, organized from 1373 and formally chartered as the Worshipful Company of Scriveners in 1617, drafted deeds, bonds, wills and letters for clients who could not write elegant legal English themselves. Rising general literacy and the standardization of legal drafting inside solicitors' own offices absorbed the trade by the late nineteenth century.
Before typewriters, law offices employed rooms of clerks whose entire job was to hand-copy documents — contracts, pleadings, correspondence — in fair copy, a role famously fictionalized in Herman Melville's 1853 story Bartleby, the Scrivener. Mass adoption of the typewriter from the 1870s, followed by carbon paper and later photocopiers, eliminated the trade within a few decades.
Before juries, European courts asked God to decide: a priest blessed the red-hot iron or the pool of cold water, and guilt hung on whether the burn festered or the body floated. When the Fourth Lateran Council forbade clergy to take part in 1215, the system collapsed almost overnight — and England, suddenly without a way to decide guilt, expanded the fledgling jury trial to fill the vacuum, redirecting the whole common-law tradition.
Litigants in medieval trial by battle could hire a professional to fight in their place, and institutions that litigated constantly — monasteries, cathedrals, towns — kept champions on retainer. England forgot to abolish the underlying right until it was invoked one last time: in Ashford v Thornton (1818), murder defendant Abraham Thornton lawfully demanded battle, his accuser declined to fight, and Thornton walked free. Parliament abolished trial by battle the next year.
The general eyre sent royal justices through every English county with power to investigate everything at once — crimes, taxes, the misdeeds of local officials — in sessions so sweeping, and so profitable to the crown in fines, that chroniclers record communities dreading the visitation and men fleeing before it. The eyre collapsed under its own procedural weight in the mid-fourteenth century, replaced by regular, narrower assize circuits with professional judges.
Protected by a near-universal ancient taboo against harming a messenger, heralds carried declarations of war, truce offers and formal challenges between rulers who might otherwise have killed any other stranger crossing into hostile territory. As permanent embassies, written treaties and professional diplomats took over the messenger's function, the herald survived mainly as a ceremonial court title rather than a working diplomatic role.
Interpreter-diplomats fluent in Ottoman Turkish, Arabic, Persian and European languages, dragomans were indispensable intermediaries for European embassies in Constantinople, often wielding real influence over negotiations their employers could not otherwise conduct. Rising European language training, consular reform and the Ottoman Empire's own dissolution after 1922 gradually eliminated the specialized, often hereditary dragoman families that had once controlled the role.
Before computers, every classified telegram or cable had to be hand-encrypted and hand-decrypted using codebooks and cipher machines by dedicated clerks working around the clock in embassy communications rooms. Electronic encryption and, later, computerized cable systems automated the work almost completely by the 1980s, eliminating a role once considered one of an embassy's most sensitive postings.
Before any public police force existed, theft victims in England paid private "thief-takers" a reward to recover stolen goods or catch the culprit — a system so easily corrupted that London's most notorious thief-taker, Jonathan Wild, secretly ran the theft rings he was paid to solve, until he was hanged in 1725. The role withered once Bow Street's paid constables, and later Peel's salaried force, removed the financial incentive to profit from crime instead of preventing it.
London's first semi-professional detective force, founded by magistrate Henry Fielding and expanded by his half-brother John, investigated crimes for a fee paid by victims or the court, alongside foot and horse patrols covering the city's main roads. Absorbed into the Metropolitan Police's growing detective branch through the 1830s, the Runners were formally disbanded in 1839, their functions folded into the new civil force.
Under the Statute of Winchester, every English parish had to supply an unpaid, rotating watchman — an ordinary tradesman or laborer serving a term of duty he neither trained for nor particularly wanted — to patrol at night and answer the hue and cry. Widely mocked as incompetent by the eighteenth century (Shakespeare's bumbling constable Dogberry drew directly on the type), the role disappeared once Peel's paid, trained constables took over the same streets.
For two centuries after the Great Fire of London, much of British firefighting was a private subscription service: insurers' uniformed brigades protected buildings displaying their company's lead fire mark, and tales — partly embellished — tell of crews standing down at uninsured houses. The system's inefficiency became indefensible; the companies merged their brigades under James Braidwood in 1833, and the Metropolitan Fire Brigade Act finally made London's firefighting a public service in 1866.
London's early water mains were wooden pipes buried under the streets, and getting water at a fire meant finding and opening them. The turncock was the water company's man who knew where every main and fire plug lay and was paid a reward for arriving fast and turning the water on. Cast-iron mains and pressurized hydrants — and eventually municipal waterworks — dissolved the trade into the modern water utility.
For most of the twentieth century, wildfires were spotted by people living alone in towers on mountaintops; the US built thousands of lookout towers, many by Depression-era CCC crews, and writers from Jack Kerouac to Norman Maclean served or wrote in them. Aircraft patrols, satellites and AI-monitored camera networks have replaced nearly all of them, though a few hundred staffed towers still watch the ridgelines each summer.
Ancien-régime France leased the right to collect royal taxes to private financiers organized as the Ferme générale, who kept a cut and fronted the crown's revenue in advance — a role that concentrated enormous, resented private profit inside a public function. The French Revolution abolished the system in 1791, replacing private tax collection with salaried state officials.
Under America's spoils system, a change of president could mean wholesale replacement of federal clerks, postmasters and customs officers with the winning party's supporters, regardless of any relevant skill. The 1883 Pendleton Act's competitive examinations gradually eliminated the role, though its logic survives narrowly in the several thousand political appointments an incoming US administration still fills without exam.
Britain's 1834 Poor Law Amendment Act created local officials empowered to decide, parish by parish, who was destitute enough to receive relief, usually inside a deliberately harsh workhouse system meant to discourage all but the truly desperate from applying. The 1948 National Assistance Act abolished the Poor Law entirely, folding its function into the new, centrally administered welfare state.
Long before electronic machines, 'computer' was a job title for a person — often a woman — who performed mathematical calculations by hand or with a mechanical calculator: astronomical tables, artillery trajectories, NASA orbital paths. Electronic computers took over the calculations from the 1950s and 1960s onward, and by the time the job vanished it had already lent the machine its name.
Mostly women, keypunch operators typed data and even program source code onto punched cards on machines like the IBM 026 and 029, one card per line of a program. Interactive terminals and video screens let programmers type code directly into the computer, and the job disappeared within a generation.
In the web's first decade, one 'webmaster' often designed, coded, wrote the copy for, and administered a whole website — the word entered dictionaries in 1993 and got its own reserved email address by internet standard in 1997. As sites grew complex, the role split into front-end developer, back-end developer, DevOps engineer and content editor, and 'webmaster' faded from job listings.
Specialists who interviewed human experts — doctors, geologists, chemists — and hand-translated their know-how into thousands of if-then rules for expert systems like MYCIN and XCON. The job largely vanished when expert systems proved too brittle and expensive to maintain, and statistical machine learning replaced hand-written rules with rules learned automatically from data.
Before deep learning, getting a computer-vision or speech system to work well depended on researchers hand-designing the right input features — edge detectors like SIFT and HOG for images, cepstral coefficients for audio — a specialized craft in itself. Networks that learn their own features directly from raw data made most of this design work obsolete within a few years of 2012.
Companies like Symbolics and Lisp Machines Inc. built and sold specialized workstations optimized to run the Lisp programming language AI research depended on, employing engineers to design, sell and maintain them. Cheaper general-purpose workstations caught up in raw performance by the late 1980s, and the entire Lisp-machine industry collapsed within about two years — a symbol of the second AI winter.
Before electronic computers, aerospace research organizations like NACA and later NASA employed rooms of mathematicians — disproportionately women, including Katherine Johnson and Dorothy Vaughan at Langley — to perform trajectory and aerodynamic calculations by hand or with mechanical calculators. Electronic computers took over the raw calculation from the late 1950s onward, and the surviving human specialists were retitled 'aerospace technologists' or engineers rather than replaced outright.
A third cockpit crew member responsible for monitoring engines, fuel and pressurization systems on complex piston and early jet airliners, reading dozens of analog gauges a pilot could not watch alone. Automated 'glass cockpit' systems on aircraft like the Boeing 757/767 and Airbus A320 (1980s) moved that monitoring to onboard computers, and two-pilot crews became the airline standard, ending the role on new aircraft designs.
Before computer-aided design, loftsmen worked full-scale on a factory floor called the mold loft, fairing an aircraft's compound curves by hand with long flexible battens, lead weights and chalk lines so every department built to the same true shape. Computer-aided design systems like CATIA, adopted industry-wide through the 1980s and 1990s, moved that work into software, and the mold loft floor disappeared from aircraft factories.
The 'navigators' who dug Britain's canals and then its railways by pick, shovel and barrow were the muscle of the heroic age — roughly 200,000 worked on British railways at the 1840s peak, living in shanty camps with a fearsome reputation and a death rate to match. Steam excavators, and later diesel plant, ended the trade; the modern machine operator moves in a day what a navvy gang moved in a season.
Before electronic computing, engineering offices employed rooms of 'computers' — increasingly, from the early 20th century, women — grinding through stress tables, survey reductions and hydraulic calculations by hand and slide rule. Electronic computers and finite-element software erased the job title within a generation, though its holders' work sits silently inside every dam and bridge designed before 1960.
Every engineering drawing once had to be copied in ink onto linen or film before it could be blueprinted, a precision trade — again largely staffed by women — with its own apprenticeships, pens and pride. Computer-aided design killed tracing outright in the 1980s: AutoCAD shipped in 1982, and within a decade the drawing office's ranks of tracing tables were gone.
Before the transistor, radios, early computers and telephone amplifiers all depended on engineers skilled at designing around fragile, power-hungry, heat-generating vacuum tubes. Within about a decade of Bell Labs' 1947 demonstration, the transistor made most of that specialized knowledge obsolete, and vacuum-tube design largely survived only in guitar amplifiers and a few legacy military systems.
Before computer-aided design tools existed, chip layouts were hand-drawn at huge scale and cut from sheets of red-and-clear Rubylith film on precision cutting tables, then photographically reduced onto the masks used to pattern a wafer. The Mead–Conway design methodology and digital layout software of the 1980s eliminated the physical cutting step almost entirely.
The earliest transistors, and the engineers who understood how to manufacture them reliably, were built around germanium rather than silicon. Once Gordon Teal's silicon transistor proved far more heat-tolerant at Texas Instruments in 1954, germanium expertise stopped being a viable specialty within about a decade, as the whole industry re-tooled around silicon.
Early industrial robots like Unimate were programmed by a specialist who physically grabbed the arm and walked it through the exact motions a job required, recording the path onto a magnetic drum for playback. CAD-linked offline programming and simulation software, standard by the 1990s, moved that work from the factory floor onto a screen.
Early numerically controlled machine tools, direct ancestors of robotic motion control, were programmed by punching instructions onto rolls of paper tape, a slow process specialists trained in for years. Computer-aided manufacturing software from the 1970s and 1980s let engineers generate machine code straight from a CAD model, and the tape punch disappeared from machine shops.
Factories once employed toolmakers who hand-built custom metal jigs and fixtures to hold every part in exact position for assembly, since neither a human nor an early machine could reliably locate a part on its own. Vision-guided robotic grippers, widespread by the 1980s, let robots find and grasp parts directly, and the bespoke fixture-building trade shrank into a specialty rather than a factory-wide necessity.
When one mainframe occupied a locked room, physical keys and sign-in sheets could control most access. Distributed networks made that narrow gatekeeping role insufficient; identity administration and endpoint security replaced it.
Security teams once dialed blocks of telephone numbers to find modems connected to corporate systems. Internet-facing asset discovery and cloud inventories displaced the telephone-based practice.
Technicians manually installed signature updates on individual PCs. Central endpoint-management and cloud-delivered protection absorbed the work into broader security operations.
A researcher would email a serialized model and instructions to an application team. Registries, versioned artifacts and deployment pipelines replaced the informal handoff.
Teams recorded runs, parameters and metrics in local files or spreadsheets. Experiment-tracking systems now preserve artifacts, code versions and comparisons centrally.
Operations staff ran periodic scripts to produce predictions. Scheduled workflows, managed platforms and automated quality checks absorbed the repeated execution.
Craft workers cut and repaired canvas sails for mechanical windmills. Enclosed, aerodynamic blades and industrial turbine manufacture replaced their local, seasonal trade.
Municipal workers lit and extinguished gas street lamps by hand. Electric distribution networks eliminated the daily route and created electrical maintenance work instead.
Workers fed coal boilers and controlled combustion by hand. Automated fuel handling and the shift away from coal generation removed much of the occupation.
Before the word 'physicist' was coined by William Whewell in 1840, people investigating the physical world called themselves natural philosophers, a title that covered chemistry, biology and what would later separate out as physics under one broad umbrella. As universities created dedicated physics chairs and journals through the nineteenth century, the older, broader title faded out of use.
Before electronic computers, physics research groups — including the Manhattan Project at Los Alamos — employed rooms of people, disproportionately women, to perform the repetitive numerical calculations a theory needed checked by hand or with mechanical calculators. Electronic computers such as ENIAC (1945) and its successors took over that work through the 1950s, and the job title disappeared.
Before physics settled into universities, showmen toured Europe and America performing electricity and magnetism as public spectacle — charging Leyden jars, 'electrifying' volunteers pulled from the audience — part entertainment, part popular science education. As the discipline professionalized into laboratories and lecture courses, the traveling demonstrator largely disappeared.
Wealthy amateurs with no university post — clergymen, landowners, retired officers — dominated natural history for over two centuries, publishing in societies like the Royal Society and filling private cabinets with shells, fossils and pinned insects. University departments and paid research posts professionalized the field from the late 1800s, closing off a role that had never required formal training, only leisure and curiosity.
Naturalists like the young Alfred Russel Wallace supported themselves entirely by collecting exotic specimens abroad and selling them to museums, wealthy private collectors and dealers back home — a genuine trade with its own market prices per bird or beetle. Conservation law, customs restrictions and the rise of salaried museum expedition staff gradually closed off freelance collecting as a way to make a living.
Before pharmacology and botany split into separate disciplines, apothecaries trained for years to identify medicinal plants correctly by sight, smell and taste, since a misidentified herb could kill a patient rather than cure them. Chemical analysis, standardized dosing and formal pharmacy licensing in the 19th century replaced this plant-identification craft with laboratory-verified medicine.
For fourteen centuries alchemists pursued transmutation and the elixir of life with royal patrons, coded manuscripts and real laboratory skill — Boyle and Newton both practiced seriously. The trade's respectability died in stages as chemistry professionalized; a late marker came in 1782–83, when English chemist James Price claimed to turn mercury into gold, was challenged by the Royal Society to repeat the feat before witnesses, and drank prussic acid in front of the delegation instead. The apparatus, and the ambition to remake matter, passed to chemistry.
Gunpowder needed potassium nitrate, and before industrial chemistry the only source was nitrate-rich earth from dovecotes, stables and cellar floors. English "petermen" carried royal warrants entitling them to dig up private property — even church floors — and were widely loathed for it. The trade collapsed when imported Chilean and Indian nitrates undercut it in the nineteenth century, and the Haber–Bosch process finally made nitrogen fixation a factory product rather than something scraped from the ground.
Indigo, "blue gold," supported vast plantation economies in India and the Americas. Adolf von Baeyer synthesized the dye molecule in 1880, and after an 18-year, roughly 18-million-goldmark development effort BASF put synthetic indigo on the market in 1897. Indian natural indigo exports collapsed within two decades, and the coercive planting system left behind in Bihar became the target of Gandhi's first Indian civil-disobedience campaign at Champaran in 1917 — a whole agricultural profession erased by one laboratory molecule.
Long before electronic computers, teams of workers — disproportionately women, such as the 'Harvard Computers' who catalogued stars at the Harvard College Observatory from the 1880s, and NASA's Katherine Johnson, Dorothy Vaughan and Mary Jackson, who hand-calculated orbital trajectories into the 1960s — performed the mathematical labor now done by software. Electronic computers absorbed the role within a generation of becoming reliable and affordable.
Following Herman Hollerith's punched-card tabulator, built for the 1890 US Census, keypunch operators spent decades transcribing paper records onto cards that mainframe computers could read, a specialized clerical skill taught in dedicated training courses. Direct-entry computer terminals made the role largely obsolete by the 1970s and 1980s.
Corporate 'data processing' departments once employed programmers, often working in COBOL, whose main job was writing and running scheduled overnight batch jobs that produced management's printed reports by the next morning. Self-service business-intelligence dashboards and ad hoc query tools let managers pull their own numbers on demand, closing this specialty out almost entirely by the 2000s.
For most of recorded history, casting horoscopes was the astronomer's actual paying job: Babylonian scholars read the sky for kings, China's Astronomical Bureau interpreted portents for emperors into the Qing dynasty, and Johannes Kepler — discoverer of the planets' true orbits — financed his physics as an imperial astrologer, writing that astrology was the foolish daughter who fed her wise mother. European astronomy shed the role during the eighteenth century as universities and academies took over the salaries.
Britain's Nautical Almanac, founded in 1767, was calculated by a distributed network of freelance human computers; Harvard College Observatory hired women from 1879 to measure and classify stars on glass plates at around 25 to 30 cents an hour; and NASA's computing pools, made famous by Katherine Johnson, carried the trade into the space age. Electronic computers erased the job title within a generation — though the word itself survives on every desk.
Before radio signals, observatories were where time came from: Greenwich dropped its public time ball from 1833 so ships on the Thames could set their chronometers. The Belville family made a business of it — John Belville, and later his daughter Ruth, carried a pocket chronometer nicknamed Arnold from Greenwich to London subscribers each week, selling the time itself. Ruth Belville was still making her rounds in 1940, in her eighties, as the telephone speaking clock finally ended the trade.
For two centuries, "computer" was a job title: teams of people calculating by hand, from the British Nautical Almanac's network of home-working calculators (begun 1767) to the Harvard Observatory's women computers and NASA's West Area Computing unit, where Katherine Johnson checked orbital trajectories John Glenn refused to fly without. Electronic computers erased the trade within roughly a decade of ENIAC's 1945 debut — the machines took the workers' very name.
The maestri d'abaco of Italian commercial cities and the Rechenmeister of German towns taught merchants' sons practical arithmetic — currency exchange, interest, partnership divisions — in private schools outside the universities. Adam Ries's German-language arithmetic books (from 1522) were so authoritative that "nach Adam Riese" ("according to Adam Ries") still means "correctly calculated" in German today. Printed textbooks and universal schooling slowly dissolved the trade.
For centuries the title "mathematicus" meant a court employee who did astronomy, calendar work and astrology as one job: Johannes Kepler, Imperial Mathematician to Rudolf II from 1601, cast horoscopes for the general Wallenstein while writing the laws of planetary motion, and frankly called astrology the "foolish daughter" who fed her sensible mother, astronomy. The scientific revolution split the professions and starved the astrological half of its standing.
Teams manually calculated tables for navigation and science before electronic computation displaced the work.
Technicians maintained thousands of failure-prone vacuum tubes until transistors and integrated circuits replaced them.
Laboratory workers interpreted photographic spectra by hand before digital detectors and software analysis.
Long before electronic computers, teams of workers — disproportionately women, such as the 'Harvard Computers' who catalogued stars at the Harvard College Observatory from the 1880s, and NASA's Katherine Johnson, Dorothy Vaughan and Mary Jackson, who hand-calculated orbital trajectories into the 1960s — performed the mathematical labor now done by software. Electronic computers absorbed the role within a generation of becoming reliable and affordable.

Corporate 'data processing' departments once employed programmers, often working in COBOL, whose main job was writing and running scheduled overnight batch jobs that produced management's printed reports by the next morning. Self-service business-intelligence dashboards and ad hoc query tools let managers pull their own numbers on demand, closing this specialty out almost entirely by the 2000s.
For centuries the master mason was architect, structural engineer and site foreman in one person, trained inside a guild lodge and trusted to design a cathedral while personally cutting its stone. As academies formalized architectural theory and licensing laws from the 1830s onward split legal design authority from on-site execution, the role was carved in two: an 'architect' who designs and a 'contractor' who builds, with neither retaining the master mason's full authority over both.
Large architecture offices once employed rooms of draughtsmen — a distinct, non-licensed trade — who translated an architect's sketch into precise scaled drawings in ink on linen or film, often spending years moving from tracer up to chief draughtsman without ever becoming an 'architect' of record. AutoCAD, released in 1982, and the CAD software that followed emptied the drafting room through the 1990s; the title survives mainly as 'CAD technician', doing similar work on a screen.
Before renderings were generated on a computer, firms hired specialist illustrators — Hugh Ferriss in New York was the most celebrated — to hand-paint the dramatic perspective views used to sell an unbuilt design to a client or a competition jury. Ferriss's charcoal renderings of stepped-back 1920s skyscrapers shaped how an entire era imagined the modern city. Digital rendering software eliminated the trade almost completely by the 2000s, and AI image tools have since taken over most of what remained.
Theatrical newsreels, Pathé News, Universal Newsreel and Fox Movietone among them, employed their own directors to shoot and cut short factual programmes screened before every feature film, a directing career built entirely around weekly deadlines rather than narrative control. Television news made theatrical newsreels obsolete through the 1960s; Universal Newsreel, the last major American one, shut down in 1967.
Golden Age Hollywood directors were routinely salaried studio employees under exclusive multi-year contracts, assigned to projects rather than choosing them and rarely controlling the final cut of their own films. The 1948 United States v. Paramount Pictures antitrust ruling forced studios to sell their theatre chains and abandon exclusive contracts, and within a decade most directors were negotiating film by film as freelancers instead.
Studios like Republic Pictures and Universal employed directors who specialized entirely in serials, action stories released in weekly twelve- to fifteen-chapter installments that each ended on a cliffhanger, shot fast and cheap for Saturday matinee audiences. Republic released its last American theatrical serial in 1955, and the format vanished from cinemas within a couple of years as television delivered a weekly cliffhanger straight into living rooms instead.
From 1836, Paris dailies fought circulation wars with the roman-feuilleton — a novel installment across the bottom of the front page. Eugène Sue's The Mysteries of Paris (1842–43) gripped France chapter by chapter, and Dumas kept teams of collaborators supplying copy by the column. Radio drama, cinema and the cheap paperback killed the trade between the wars; its cliffhanger craft survives in television writers' rooms.
For most of the Victorian era, British novels appeared in three volumes at the artificial price of 31 shillings and sixpence — roughly a week's wages — a format sustained by Mudie's Select Library, which bought thousands of copies and rented them out volume by volume. Novelists padded plots to fill the third volume. In 1894 Mudie's and W. H. Smith refused the price, and within three years the format was effectively extinct.
After Frank Munsey converted The Argosy to all-fiction pulpwood paper in 1896, hundreds of American magazines paid around a cent a word for westerns, detective stories and space opera, and a fast typist could earn a middle-class living on volume alone. Raymond Chandler and Isaac Asimov apprenticed there. Paperback originals and television destroyed the pulps in the early 1950s; the surviving titles converted to digest size or died.
A Kapellmeister directed and composed for one aristocratic or church household's musical establishment entirely, much like Bach at Leipzig or Haydn at Esterházy — a stable but fully dependent post that largely disappeared as the French Revolution and the rise of public concerts broke apart Europe's system of court patronage over the following decades.
Silent-film theaters employed organists and small orchestras to improvise or perform scored accompaniment live during every screening, one of the largest sources of steady musical employment in early 20th-century cities. The job vanished almost overnight after The Jazz Singer (1927) proved synchronized recorded sound worked, and theaters switched to sound film within a few years.
Before notation software, a copyist hand-transcribed a composer's full score into the separate individual parts each orchestral player reads from — skilled, essential and entirely manual work. Programs like Finale (1988) and Sibelius (1993) let composers generate parts directly from a digital score, and the standalone copying trade largely disappeared within a decade.
For three centuries, painters like Nicholas Hilliard at the Tudor court made tiny portraits in watercolor on vellum or ivory — carried in lockets, exchanged in courtships, sent with marriage negotiations. The daguerreotype of 1839 did the same job faster, cheaper and with a machine's authority; within two decades the trade had collapsed, and many miniaturists survived by becoming photographers or hand-tinting other people's photographs.
In most European towns, nobody could legally take painting commissions or sell pictures without membership in the local guild of Saint Luke, which enforced apprenticeships, materials standards and monopoly. Vermeer served twice as headman of Delft's guild. The French Revolution's d'Allarde law abolished guilds in 1791, and Napoleonic rule swept away the Dutch and Flemish guilds soon after — ending five centuries of licensed painting.
Through most of the twentieth century, film posters and cinema-front billboards were painted by hand at enormous scale — nowhere more than in India, where Bombay studios employed crews to repaint hoardings weekly, and where a young M. F. Husain, later India's most famous modern painter, started out painting cinema billboards for a few annas per square foot. Digital flex printing killed the trade almost everywhere within a decade of the mid-1990s.
Before video, arcade amusements were built from relays, motors, lamps and mirrors — periscope gun games like Sega's Periscope (1966), driving cabinets with spinning painted drums. Their designers were mechanical engineers who sculpted play out of physical linkages. Within roughly five years of Pong, microprocessor video games had erased the trade; pinball survived only by converting to solid-state electronics itself in 1977–79.
Don Bluth's laserdisc hit Dragon's Lair (1983) and the CD-ROM boom of the early 1990s briefly created a hybrid profession: designers who directed film shoots — actors, sets, branching scripts — for interactive movies like Night Trap. Real-time 3D graphics after Doom (1993) made filmed footage look rigid and quaint, and the discipline collapsed within five years, surviving only in occasional revivals.
For two decades, one-person designers shipped free browser games to portals like Newgrounds and Kongregate, iterating in public and living off ad and sponsorship deals — the training ground for hits like Super Meat Boy's creators. Adobe ended Flash support on 31 December 2020, browsers deleted the plugin, and the trade dissolved into mobile and itch.io; volunteer projects now preserve tens of thousands of its games as history.
Specialists once studied how operators worked around batch-computing constraints; interactive systems absorbed much of the role.
Early web teams often asked one generalist to build, write, test and maintain a site before design and research separated.
Traditional market research reports often delivered opinions after a launch decision; iterative product research displaced much of this slower handoff.
England's overseas trade was long the legal monopoly of chartered merchant guilds, above all the Company of Merchant Adventurers of London, which controlled the export of woolen cloth to the Low Countries and Germany from the early fifteenth century. Free-trade politics and interloping merchants eroded the monopolies through the seventeenth century, and the company's Hamburg successor was finally dissolved in 1809 — the entrepreneur no longer needed a royal charter to trade abroad.
For centuries the peddler carried retail to the countryside on his back, extending goods and credit where no shop existed; the trade was a classic first rung for immigrants, and several retail dynasties climbed it — Adam Gimbel peddled along the Mississippi before opening the Vincennes, Indiana store in 1842 that grew into Gimbels department stores. Mail-order catalogues, the department store and finally the automobile erased the trade across the industrialized world by the 1930s.
After the Treaty of Nanking opened China's ports, foreign trading houses hired Chinese merchant-managers — compradors — to run their local buying, selling and staff, straddling two commercial worlds on commission. Some, like the reformer-merchant Zheng Guanying, became industrialists and public figures in their own right. The role, long resented as a symbol of foreign economic control, was abolished outright after the Communist victory of 1949.
For nearly three centuries, London split its market in two: brokers dealt with the public, and jobbers — wholesalers standing at pitches on the Exchange floor — quoted them two-way prices, never dealing with outside clients directly. Daniel Defoe was already denouncing "the villainy of stock-jobbers" in 1701. The Big Bang of 27 October 1986 abolished the broker–jobber separation overnight, and the trade vanished into the dealing desks of the banks that bought the old firms.
London's discount houses were a unique species: firms whose partners walked the City in top hats, borrowing banks' spare cash overnight and using it to discount trade bills, sitting formally between the banking system and the Bank of England. For over 150 years they were the channel through which the Bank steered interest rates. Reforms to money-market operations in the 1980s and 1990s dissolved their privileged role, and the last discount houses closed or converted around 2000.
Born, by Exchange legend, when a broker who had injured his leg in 1875 stayed at one post trading a single stock, the specialist system gave one firm the franchise — and the obligation — to make a continuous market in each NYSE-listed share from a fixed spot on the floor. Electronic trading eroded the role for years before the NYSE formally replaced specialists with "designated market makers" in 2008, ending 130 years of single-stock stewardship.
For seven centuries the English Exchequer recorded debts on notched wooden tally sticks, split lengthwise so debtor and creditor each held half of an unforgeable record. The system was abolished in 1826, and in 1834 the burning of two cartloads of obsolete tallies in the Palace of Westminster's furnaces set the chimneys alight and burned down Parliament — a fire J. M. W. Turner painted from the Thames.
The high stool, the quill, the copperplate hand and the bound ledger defined clerical life for three centuries — Bob Cratchit, shivering in Scrooge's counting-house at fifteen shillings a week, is the type's monument. Adding machines, typewriters and card-index systems dissolved the all-round ledger clerk's craft into machine operation within a generation either side of 1900.
Dorr Felt's Comptometer, patented in Chicago in 1887, was a key-driven calculator fast enough that firms hired entire floors of trained operators — overwhelmingly women, certified by dedicated Comptometer schools that taught touch operation at speed. Electronic calculators and mainframe computers erased the trade in the 1960s and 70s, taking one of the era's largest skilled office occupations for women with it.
For centuries the crier was the mass medium: a licensed officer who rang a bell and shouted official proclamations, and — for a fee — merchants' announcements, in an age when most customers could not read. Mass literacy and cheap newspapers erased the commercial role through the nineteenth century, leaving today's ceremonial criers, who survive mainly in British and Commonwealth pageantry and competitive "crying" championships.
Traveling shows toured rural America and Europe mixing free entertainment — music, comedy, staged "miracle cures" — with high-pressure sales of patent medicines, many of them alcohol or opium in a fancy bottle. Outfits like the Kickapoo Indian Medicine Company ran dozens of troupes at their 1880s peak. The US Pure Food and Drug Act of 1906 and tightening drug regulation through the 1930s killed the trade, and its shows faded with it.
For a century, brands like the California Perfume Company (later Avon, founded 1886) and the Fuller Brush Company (1906) reached households through armies of commissioned callers — a genuine mass channel and, for women especially, a rare open sales career. Two-income households emptied daytime homes, Encyclopaedia Britannica ended its famous door sales in 1996, and the US National Do Not Call Registry of 2003 marked the channel's effective end as mainstream marketing.
Neil McElroy's original title for P&G's product-owning executives never spread far under that exact name. By the 1950s it had split in two: 'brand manager', which stayed inside marketing departments, and the newer 'product manager', which technology companies began applying to a broader, less advertising-focused job.
In waterfall-era corporate software, a systems analyst spent months interviewing stakeholders and writing a lengthy requirements document before a single line of code was written, then handed it to engineers with little further involvement. Agile and Scrum's arrival in the 1990s and 2000s collapsed that handoff, and much of the analyst's job was absorbed into the modern product manager and product owner roles.
Growing hardware and semiconductor companies once hired engineers who doubled as the public face of a product line, writing technical specifications and pitching customers in the same job. As software product management matured into its own discipline in the 1990s, the role split into a product manager, who owns the roadmap, and a product marketing manager, who owns positioning and launch.
William Petty's followers made a trade of estimating national population, income and taxable wealth from hearth-tax rolls, burial registers and trade ledgers — Gregory King's 1696 tables of England's social classes were consulted for a century. The craft had no successor title: its estimation work was absorbed into government statistics, and its policy ambitions into political economy, leaving the name behind by the time the first census offices opened.
Before electronic machines, statistical and economic calculation was done by rooms of clerks — very often women — grinding through index numbers, life tables and national accounts by hand and by mechanical calculator. Early econometrics ran on their labor: Wassily Leontief's input-output tables of the US economy required years of organized hand computation. Electronic computers erased the occupation within roughly a decade of arriving.
The Soviet State Planning Committee, Gosplan, employed thousands of economists and engineers in Moscow to set output targets and prices for an entire economy through "material balances" — vast hand-built ledgers matching every input to every use across tens of thousands of products. It was the largest concentration of economic planners ever assembled, and the profession vanished almost overnight when the USSR dissolved in December 1991.
Manual logs gave way to digital monitoring systems.
Integrated compliance systems absorbed narrow reporting work.
Databases and reporting platforms reduced manual compilation.
Greece's itinerant professors of rhetoric and public life traveled city to city charging what the market bore — Protagoras was said to command fees that made him richer than sculptors and generals. Plato and Aristotle attacked the trade so effectively that "sophist" became an insult for a clever deceiver, and the fixed philosophical schools of Athens absorbed the demand. The traveling wisdom-seller vanished; the word for his craft never recovered.
Medieval universities were staffed largely by their own newest graduates: a Master of Arts was required to teach — "necessary regency" — for a year or two after graduating, lecturing on the set texts while pursuing a higher degree. The system made every university self-staffing, and made teaching a toll paid on the way to somewhere else. Endowed chairs and salaried, permanent professorships gradually replaced the regents, and the graduate-who-must-teach survives only in the modern teaching assistantship.
For a century, traveling public lecturers were how much of small-town America met ideas: the lyceum movement, founded in 1826, and its Chautauqua successors booked speakers into thousands of towns. Ralph Waldo Emerson made much of his living giving well over a thousand lyceum lectures; Frederick Douglass and Mark Twain worked the same circuits. Radio and cinema took the audience in the 1920s and 30s, and the itinerant lecture hall folded into broadcast media and, eventually, the recorded university lecture.
Ireland's penal laws barred Catholics from running schools, so itinerant masters taught reading, arithmetic, Latin and Greek illegally — at first literally beside hedges, later in barns and cabins — paid in coins, turf or lodging by rural parishes. By 1824 a government survey found hundreds of thousands of children attending them. The free national school system of 1831 absorbed and erased the trade within a generation.
Across England, colonial America and New England, women taught village children their letters and catechism in their own kitchens for a few pence a week, often while spinning or minding infants — for many children the only schooling they ever got, and for many women the only paid intellectual work available. Compulsory state schooling, from England's 1870 Education Act onward, ended the dame school within decades.
In the Bell–Lancaster monitorial system, one master ran a school of several hundred by drilling older pupils — monitors — who each recited the lesson to a bench of younger ones. Joseph Lancaster's Borough Road school in London claimed a thousand pupils under a single teacher. Cheap enough to spread across Britain, the Americas and colonial empires, the system faded once trained adult teachers became affordable, beginning with England's pupil-teacher scheme of 1846.
For nearly a millennium, the year-by-year memory of Latin Europe was kept by monks who noted battles, comets and famines in the margins of Easter tables, compiling them into house chronicles that remain medievalists' backbone sources. The trade died with its institutions: printing made copying obsolete, and the dissolution of the monasteries — England's alone, in the 1530s, closed nearly 900 religious houses — scattered both the annalists and their libraries.
From Carolingian court annalists to the Ottoman şehnameci composing illustrated books of kings and Spain's cronista real, dynasties long kept salaried writers to record — and burnish — their deeds. Korea's version was the most rigorous: Joseon's sagwan compiled the Veritable Records for five centuries under a rule that even the king could not read them, a protection modern civil services rarely match. Archive-based professional history and the fall of the dynasties themselves ended the post.
The gentleman antiquary — collector of coins, inscriptions, charters and ruins, embodied by figures like William Camden, whose Britannia surveyed England county by county from 1586 — was early modern Europe's primary engine of historical evidence. The nineteenth century dismantled the type: its manuscripts went to national archives, its digs became archaeology, its philology became university source criticism, and the learned amateur was replaced by three separate salaried professions.
Building on Franz Joseph Gall's claim that character faculties sat in specific brain organs readable as skull bumps, phrenologists read heads for a fee across Europe and America — the Fowler brothers' New York firm made it a mass business, examining clients including Walt Whitman. The science was demolished by mid-century, but the trade lingered for decades; its one durable idea, that brain functions localize, survived into real neuroscience.
Franz Anton Mesmer treated fashionable Paris with "animal magnetism," inducing trances and convulsive crises around magnetized tubs. A 1784 French royal commission that included Benjamin Franklin and Antoine Lavoisier found no magnetic fluid whatsoever — one of history's first placebo-controlled investigations — yet mesmerism thrived for decades more. Scottish surgeon James Braid stripped away the theatrics and renamed the residue "hypnotism" in 1843, handing it on to Charcot, and through him to Freud.
The 19th century's physician of the insane — from the French aliéniste — presided over the era's vast public asylums, testifying in courtrooms on "moral insanity" and managing institutions that often held thousands. The title faded in the early 20th century as "psychiatrist" replaced it and treatment began moving out of asylums; clinical psychology grew up partly in the space the asylum system left behind.
The Ottoman Empire outsourced its diplomacy with Europe to a corps of official interpreter-diplomats, the dragomans. From 1661 the post of Grand Dragoman — first held by Panagiotis Nikousios and then by Alexander Mavrocordatos — became the near-monopoly of Phanariot Greek families, who parlayed language skill into real power, negotiating treaties and eventually ruling Ottoman provinces. The role died with the empire itself and the rise of foreign ministries staffed by trained diplomats who spoke their own languages.
When Tokugawa Japan closed itself to the West, every word exchanged with Europe passed through a hereditary guild of Japanese interpreters of Dutch at Nagasaki — by the eighteenth century a bureaucracy of well over a hundred posts passed from father to son. They doubled as Japan's only channel for Western science, translating medical and technical books in the movement known as rangaku. The opening of Japan and the switch to English in the 1850s erased the trade within a generation.
Early modern European states corresponded in Latin, and courts kept a salaried scholar to draft and translate it. England's Council of State appointed the poet John Milton as Secretary for Foreign Tongues in 1649; he composed the republic's Latin correspondence, with Andrew Marvell later assisting, until the Restoration. As French and then national vernaculars displaced Latin in diplomacy over the eighteenth century, the office quietly ceased to exist across Europe.
For a thousand years the librarian's closest colleague was the copyist: monks and, later, lay professionals who reproduced books by hand under the direction of the armarius, the monastic officer who kept the collection and assigned the copying. Gutenberg's press, from the 1450s, could produce in a week what a scriptorium made in years; within two generations the copying rooms had emptied, though their surviving manuscripts still anchor the world's great research collections.
Before free public libraries, commercial lending libraries rented books by subscription. London's Mudie's Select Library, founded 1842, grew so dominant that its bulk orders effectively dictated the three-volume format of the Victorian novel; Boots the chemist ran a Book-Lovers' Library inside its shops from 1899. Cheap paperbacks and tax-funded public libraries destroyed the business model — Mudie's closed in 1937, Boots' library in 1966.
For over a century, armies of librarians typed, filed and cross-referenced the cards in wooden catalog drawers — a specialist craft with its own rules for filing, spacing and handwriting, standardized on the 7.5 × 12.5 cm card. MARC records and shared online cataloging made the card redundant; OCLC, which had printed more than 1.9 billion catalog cards since 1971, printed its last one in October 2015.
A short-legged breed developed purely to trot inside a wheel that turned the roasting spit over an open kitchen fire, common in English kitchens for three centuries. Cheap clockwork spit-jacks made the job, and eventually the breed itself, obsolete; by 1900 the turnspit dog was extinct.
Medieval Paris chartered its roasters, stewers (traiteurs) and pastry cooks as separate guilds, each legally forbidden from making the others' dishes — a rôtisseur selling a stew could be fined. The trades only merged when the French Revolution abolished the guild system in 1791, creating, for the first time, a cook licensed to do all of it: the modern restaurant chef.
A dedicated palace official whose job was to taste every dish before the sultan did, guarding against poison, while also training young kitchen apprentices and enforcing the palace's exacting standards. The role faded along with the Ottoman court itself, dissolved in 1922 — a job made obsolete by the end of an institution, not by a machine.
Before mechanized mills, every plank began with two men and a two-metre saw: the top-man balancing on the log, the pit-man below in a rain of sawdust, ripping timber lengthwise for hours at a stretch. Sawyers worked in paired teams as a distinct trade allied to carpentry until steam sawmills spread through the nineteenth century and erased the pit within two generations.
The maker of wooden wheels — hub, spokes and felloes fitted with shrunk-on iron tyres — was once every village's most exacting woodworker, combining carpentry, turning and smithing. George Sturt's 1923 memoir The Wheelwright's Shop documented the trade's last working generation in Farnham, England, just as the motor car and the pressed-steel wheel ended four thousand years of demand.
In the beech woods of England's Chiltern Hills, bodgers lived and worked among the trees, turning chair legs on foot-powered pole lathes and selling them by the gross to the High Wycombe chair factories. Factory turning killed the trade in the twentieth century; Samuel Rockall, commonly counted the last traditional bodger, kept working his woodland shop until his death in 1962.
Early mainsprings delivered uneven force, so watches used a fusee — a cone wound with a miniature chain of hundreds of hand-riveted links, each smaller than a grain of rice. Around Christchurch in southern England the chains were famously made by women and children, including workhouse children, paid piece rates for eye-destroying work. The going barrel and better springs made the fusee obsolete in watches by the late 1800s, and the trade vanished with it.
In Britain and Ireland's industrial towns, a knocker-up walked the streets before dawn tapping bedroom windows with a long pole — or, famously in some accounts, shooting dried peas at them — to wake workers for their shifts, for a few pence a week per client. Cheap, reliable alarm clocks, a direct product of mass watch and clock manufacturing, erased the job; the last practitioners worked into the mid-twentieth century.
Luminous watch dials created a factory trade of young women painting numerals with radium paint, trained to point the brush between their lips. At the United States Radium factory in Orange, New Jersey, and plants like it, the 'Radium Girls' developed horrific jaw necrosis and cancers; their 1927–28 lawsuits helped found modern occupational-safety law. Safer luminous compounds ended radium dial painting, and the trade with it.
The specialist who stitched gambesons and arming doublets — densely quilted padded garments worn under mail and plate, on which a knight's comfort and survival partly depended. Important enough that London's 1327 royal charter went jointly to the 'Tailors and Linen Armourers.' Gunpowder and the decline of personal armor dissolved the specialty; by the time the London guild was reincorporated as the Merchant Taylors in 1503, the armourers' half of the name was already history.
Close-fitting knee breeches, frequently of buckskin or other leather, demanded stretch-fitting skills so unlike coat work that they supported a separate trade with its own shops and apprentices. The French Revolution made the long trousers of the sans-culottes — literally 'without breeches' — a political statement, and Regency London made them fashionable. Within a generation breeches survived only at court and on horseback, and the breeches-maker's trade collapsed into general tailoring and glove-making.
In 1675 Louis XIV chartered the Paris seamstresses' guild, breaking male tailors' legal monopoly on making women's clothes; in England and America the resulting women's trade took its name from the mantua, the loose gown it made. For nearly two centuries the mantua-maker was the standard female clothing artisan — one of the few respectable skilled trades open to women. The word faded into 'dressmaker,' and Worth's couture houses and the ready-made industry absorbed the work itself.
For nearly four millennia, courts from Egypt to Versailles kept an officer whose duty was to pour the ruler's wine and taste it first against poison. In France the Grand Échanson ranked among the great officers of the crown, a post held by high nobility. The office died with the courts themselves — the French Revolution abolished it in 1789 — leaving only its ghost in the modern ritual of the sommelier tasting before the guest.
Medieval Paris licensed criers who walked the streets each morning with a jug and cup, pouring passers-by samples of whichever tavern's barrel had just been broached and shouting its price — a trade codified in Étienne Boileau's Livre des métiers around 1268. Printed announcements, bottled wine and fixed shopfronts slowly erased the job; the sommelier inherited its tasting cup and its salesmanship.
Paris chartered sworn wine broker-tasters — courtiers-gourmets-piqueurs — in 1322 to taste every barrel arriving at the city's ports, certify its soundness and broker its sale, with a legal monopoly on the trade. The Revolution's abolition of guild monopolies in 1791 ended the office's power, though a ceremonial confraternity of the name survives in Paris to this day as one of France's oldest corporations.
Whole districts — Bromsgrove and the Black Country in England, similar villages across Europe — lived by forging nails by hand at backyard hearths, whole families cutting and heading rod iron for piecework wages that were a byword for poverty. Machine-cut nails, and then cheap wire nails in the late nineteenth century, erased the trade almost completely by 1900; the nailers' cottages, with forge shops behind the kitchen, still stand around Bromsgrove.
Cradley Heath in England's Black Country hand-forged much of the world's chain, from ships' anchor cable made by gangs of men to small chain hammered by thousands of women in backyard shops. In 1910 around 800 of those women, organised by Mary Macarthur, won a ten-week strike that roughly doubled their pay under Britain's first minimum-wage law. Machine-welded chain then took the trade anyway; the last hand shops closed in the decades after the Second World War.
The wheelwright built the wooden wheel; the smith closed the partnership by forging its iron tyre and shrinking it red-hot onto the rim, a two-trade ritual performed in every market town for centuries. George Sturt's 1923 memoir The Wheelwright's Shop recorded the craft just as rubber-tyred motor vehicles ended it; by the 1950s working wheelwrights survived mainly in museums, and the tyring plate outside the smithy became an archaeological feature.
On ocean crossings, a dedicated navigator shot the sun and stars with a sextant through a transparent astrodome in the cabin roof, fixing the aircraft's position the way ship's officers had for centuries — Pan American's flying boats could not have crossed the Pacific without one. Inertial navigation systems, carried on the Boeing 747 from 1970, computed position continuously with no windows needed, and airlines retired their last navigators around the early 1980s; GPS finished the argument.
Complex piston airliners and early jets carried a third crew member facing a side panel of fuel, hydraulic and electrical controls, managing the machinery while the two pilots flew. A 1981 US presidential task force concluded two-crew jets were safe, the Boeing 757 and 767 were certified without the seat in 1982, and electronic systems monitoring did the rest; the last flight-engineer aircraft left major passenger fleets in the early 2000s.
Demobilized First World War pilots bought surplus Curtiss Jenny biplanes for a few hundred dollars and toured rural America selling five-minute rides and wing-walking shows from farm fields — for millions, the first aircraft they ever touched. The US Air Commerce Act of 1926 brought pilot licensing, aircraft airworthiness rules and inspections; the free-for-all that made barnstorming possible was regulated out of existence within a few years.
Before rockets, the edge of space belonged to balloonists in pressurized gondolas. Auguste Piccard reached 15,785 metres in 1931; the Soviet Osoaviakhim-1 crew of three died in 1934 when their record-setting flight iced up and broke apart; the US Explorer II crew touched 22,066 metres in 1935, photographing the curve of the Earth. The trade produced the pressure suits and cabin technology astronauts inherited, then vanished when rockets made balloons look slow — its last practitioner, Nick Piantanida, died in a 1966 jump attempt.
Twelve pilots flew the X-15 rocket plane off the wing of a B-52 to the edge of space — eight earned US astronaut wings for flights above 50 miles, and Joe Walker crossed the 100-kilometre Kármán line twice in 1963. For a decade it seemed winged rocket planes, not capsules, would be the path to orbit; the program ended in 1968, a year after Michael Adams died in a re-entry breakup, and the winged path lay dormant until the Shuttle partially revived it.
The Shuttle era created a category of one-flight, non-career crew members: company engineers like Charles Walker of McDonnell Douglas, the first commercial astronaut in 1984; sitting US politicians; and teacher Christa McAuliffe, who died aboard Challenger in 1986. The category never recovered its footing after that loss and effectively ended when Columbia broke up in 2003, killing payload specialist Ilan Ramon — professional career corps and, later, paying private astronauts absorbed the role.
For centuries the Royal Navy split command in two: commissioned captains fought the ship, while the sailing master — a warrant officer risen from the merchant service — navigated her, kept the log and answered for the trim and stowage. Men like Captain Cook began as masters, and William Bligh served as the master of Cook's Resolution. The rank was absorbed into the commissioned navigating branch in the 1860s, and the fighting captain finally took full charge of both the battle and the navigation.
On long trading voyages the owners embarked a supercargo — their commercial agent, who outranked the master in everything to do with buying and selling the cargo. East India Company supercargoes on the Canton run handled fortunes in tea and silver and could overrule a master's choice of port. The telegraph, then steamship liner agencies with offices in every port, made the floating merchant redundant; his commercial power flowed partly back to the master and mostly ashore.
From Marconi's first shipboard wireless sets, every large ship carried a dedicated radio officer — a separate profession with its own certificates, unions and heroes, like the Titanic's Jack Phillips, who kept sending distress calls until the power failed. The Global Maritime Distress and Safety System, fully in force on 1 February 1999, replaced the trained human ear with automated satellite and digital watchkeeping, and the job vanished from world fleets within a few years; deck officers with GMDSS certificates absorbed the work.
For most of farming's history, the most skilled worker on any farm was the one who could drive and care for its draft animals — oxen first, then horses, whose numbers in the United States peaked around 26 million in the late 1910s. The tractor erased the trade in a single generation: by 1960 working horse teams had all but vanished from American and western European fields, and the ploughman's craft survives mainly in ploughing matches, heritage farms and Amish communities.
Steam traction engines and threshing machines were too expensive for one farm, so crews traveled farm to farm each autumn, threshing the neighborhood's grain in a communal ritual of shared labor and enormous meals that rural memoirs across North America and Europe recall vividly. The combine harvester, which reaps and threshes in a single pass, dissolved the trade — and with it one of the countryside's great social institutions — by the 1950s.
For millennia the rural poor held a customary right to gather grain left behind after harvest — the Hebrew Bible's Book of Ruth turns on it, and Jean-François Millet's 1857 painting The Gleaners made it an icon of rural France. England's courts ruled in Steel v Houghton (1788) that no common-law right to glean existed, enclosure fenced the fields, and mechanical harvesters eventually left too little behind to gather; the living survives only in charity gleaning projects that harvest surplus for food banks.
The gentleman antiquary collected coins, urns and inscriptions, corresponded with learned societies and speculated about Druids, usually without recording where anything was found. Institutionalized in bodies like London's Society of Antiquaries (1707), the role was slowly strangled by the discipline it hatched: once Pitt Rivers and Petrie showed that context matters more than the object, an unprovenanced collection became a scientific embarrassment, and the antiquary gave way to the credentialed archaeologist and the museum curator.
For centuries, ground Egyptian mummy — mumia — was sold by European apothecaries as medicine, and whole mummies were exported for spectacle; Victorian showman-surgeon Thomas Pettigrew made a career of public unwrappings in 1830s London, and "mummy brown" pigment was sold to painters into the twentieth century. Egypt's antiquities laws, museum-led excavation and plain revulsion ended the trade, which survives only as a cautionary chapter in the history of collecting.
Victorian gentlemen opened ancient burial mounds as weekend sport, sometimes several in a day — Derbyshire's Thomas Bateman recorded opening hundreds in his 1861 book Ten Years' Diggings, digging fast for urns and skeletons and leaving little record of the layers. As excavation standards professionalized around 1900, barrow-digging was reclassified from respectable pastime to destruction; its surviving descendant, responsible metal-detecting, now reports finds through schemes like England's Portable Antiquities Scheme.
From at least the 11th century, organized brotherhoods of marrons guided travelers over the Great St Bernard and Mont Cenis passes, breaking trail through snow, carrying passengers' baggage and running sledge descents on the Italian side. Napoleon's carriage road over Mont Cenis, finished around 1810, and the railways and tunnels that followed erased the trade within two generations.
Nineteenth-century Alpine tariffs listed a second, cheaper class of professional below the guide: the porter, who hauled provisions, firewood and clients' baggage to the high huts and could be promoted to guide after years of service. Cable cars, supply lifts and finally helicopters removed the loads, and the rung vanished from the profession's ladder, surviving only in the aspirant guide's apprentice status.
In the first age of Alpine tourism, teams of porters carried wealthy visitors up viewpoint peaks like the Rigi in sedan chairs — Mark Twain still described the busy Rigi tourist machine in A Tramp Abroad in 1880. Europe's first mountain rack railway, opened up the Rigi from Vitznau in 1871, ended the trade almost overnight; the railways kept the tourists and dropped the porters.
Before mass literacy, official news reached most people by voice: the crier rang a bell, shouted 'Oyez,' and proclaimed ordinances, markets, wars and executions in the street, protected by law because harming the messenger meant defying the crown. Cheap newspapers and rising literacy erased the trade through the nineteenth century; it survives today only ceremonially, in the competitive town-crier championships of Britain, Canada and Australia.
Ottmar Mergenthaler's 1886 Linotype cast whole lines of type in molten lead and made the modern-length newspaper physically possible; every sizable paper on earth came to employ rooms of skilled, well-unionized operators. Phototypesetting and computers erased the craft in barely a decade — The New York Times set its last hot-metal edition on 2 July 1978, a night recorded in the short film Farewell, Etaoin Shrdlu.
Newsrooms ran on sprinting teenagers: reporters shouted 'Copy!' and a copy boy carried the typed take to the editor, the wire desk or the composing room, learning the trade by osmosis. It was journalism's classic apprenticeship — publishers and star reporters liked to boast of having started as one. Computer terminals ended the errand and, with it, the trade's most democratic side door.
The world's first photographic professionals polished silvered copper plates, sensitized them over iodine fumes and developed them over heated mercury — a hazardous chemical performance repeated for every single image, which could not be copied. Itinerant operators carried the trade to small towns and gold-rush camps across America, Europe and Asia. Frederick Scott Archer's unpatented 1851 collodion process, yielding cheaper and reproducible images, wiped out the daguerreotype trade in barely a decade.
For a century, while-you-wait street portraitists worked plazas and pilgrimage sites with wooden cameras that were darkrooms inside — Spain's minuteros, Afghanistan's kamra-e-faoree operators, India's Yamuna-side wedding photographers. A paper negative was shot, developed inside the box in minutes, then re-photographed to make a positive. Cheap ID-photo booths, one-hour labs and finally the smartphone erased the trade; Kabul's last practitioners were documented as a dying breed in the 2010s.
Automated minilab machines put a complete color darkroom in shopping malls and pharmacies, and by the 1990s tens of thousands of one-hour photo counters worldwide employed technicians who calibrated chemistry, corrected color and printed the world's family snapshots. Digital cameras and home printing collapsed film volume within a single decade of 2000; the surviving remnant prints from files, and the trade of judging a negative by eye is effectively gone.
Rome's combat athletes were professionals in every modern sense: recruited, contracted, trained in specialist schools with doctors and dieticians, ranked, and paid — a survivor could win fame, fortune and eventually the wooden sword of freedom. First recorded at a funeral in 264 BCE, the games ended after Christian emperors turned against them; Honorius closed the gladiator schools in 399, and combats faded from Rome in the early 400s.
Medieval tournaments were a professional circuit: knights toured between events, and winners took horses, armor and ransoms from those they unhorsed. William Marshal, later regent of England, built his early fortune this way — his biography claims five hundred knights captured. Gunpowder made heavy cavalry obsolete, and after King Henry II of France was fatally lanced through the visor at a Paris joust in 1559, the sport itself slid into ceremony and extinction.
Competitive walkers and runners once drew crowds and staggering wagers: in 1809 Captain Robert Barclay walked one mile in each of 1,000 consecutive hours at Newmarket, with bets reportedly worth 16,000 guineas riding on him. By the 1870s–80s, six-day races packed New York's Madison Square Garden with competitors covering over 500 miles for large purses. Codified amateur athletics and the bicycle boom absorbed its audience, and the trade vanished.
On the English Renaissance stage, women's roles belonged by custom to apprenticed boys with unbroken voices — the first Juliet, Ophelia and Lady Macbeth were all teenage boys trained within companies like Shakespeare's. The trade died in a single decade: the theatres reopened at the 1660 Restoration with professional actresses, Charles II's 1662 patent required women's parts to be played by women, and the boy player's entire specialty vanished.
Japan's silent cinemas employed benshi — live narrator-performers who stood beside the screen voicing every character, explaining the plot and improvising commentary. Star benshi out-earned the film actors they voiced and drew audiences on their own names; at the trade's peak in the 1920s thousands worked across Japan. Synchronized sound made them redundant within a few years, and a 1932 benshi strike against the talkies failed to slow the technology.
For half a century, North America's vaudeville circuits offered performers something acting has rarely provided since: steady, scheduled, year-round employment, playing the same polished act across hundreds of theatres. Radio and talking pictures drained its audience through the 1920s, and when New York's Palace Theatre — the circuit's summit — dropped two-a-day vaudeville in 1932, the trade collapsed, sending its survivors (among them Cary Grant and the Marx Brothers) into film.
Twin Galaxies, founded in an Ottumwa, Iowa arcade in 1981, employed and deputized referees who verified marathon high-score attempts from videotape and witness statements, feeding Guinness World Records and crowning champions like the Donkey Kong rivals of The King of Kong. Online leaderboards, streamed attempts and input-logging made the human adjudicator redundant — and the 2018 stripping of Billy Mitchell's records showed even the archive being re-refereed by software.
Korea's first pro generation held formal KeSPA licenses, earned through the semi-pro "Courage" qualifying tournament, and lived in corporate team dormitories run by SK Telecom, KT, Samsung and even the Air Force. A 2010 match-fixing scandal that ended eleven careers, and the scene's forced migration to StarCraft II in 2012, killed the license, the dormitory system's first form and the last television league within two years.
The Cyberathlete Professional League's traveling circuit created the West's first pros: players who hauled their own CRT monitors through airports to Dallas, Cologne and Singapore for weekend prize brackets in Quake and Counter-Strike, living event to event without salaries. Online qualifiers, publisher leagues and streaming income dissolved the lifestyle, and the CPL itself shut down in 2008.
After the cel patent, an entire department traced each animator's pencil line in ink onto celluloid and painted the reverse side in opaque colour, matching custom-mixed shades across thousands of frames. At Disney and Fleischer the department was almost entirely women, on lower pay and with no promotion path into animation — a 1938 Disney form letter told applicant Mary V. Ford that women were not considered for creative work. The Computer Animation Production System replaced the whole department outright on The Rescuers Down Under in 1990.
The entry rung of the craft drew the frames between a key animator's poses, matching another person's line exactly while learning timing from the inside. It was badly paid but it was a real apprenticeship, and almost every great animator passed through it. Western studios shed the role when hand-drawn features collapsed after 2004; vector in-betweening software and, since the 2020s, AI frame interpolation absorbed most of what remained. In Japan the rung survives, still paid per drawing.
Someone had to photograph the artwork one frame at a time on a downshooter stand — an Oxberry or a Soviet or Japanese equivalent — following the exposure sheet line by line, sliding cel levels, cranking the table, holding registration to a fraction of a millimetre. A single misread row meant reshooting the scene. Digital compositing, first through CAPS and then through desktop software after After Effects appeared in 1993, removed the camera and the job with it.
Early heredity advice was often entangled with coercive eugenics, including forced sterilization. Modern counseling explicitly rejects this legacy through informed consent and non-directiveness.
For decades many clinical questions relied chiefly on visible chromosome analysis; molecular tests and sequencing absorbed much of this narrower role.
Hand-drawn family trees were once the only practical record. Digital records changed the medium, though careful pedigree interviewing remains essential.
