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.
Barber-surgeon no longer exists as a living trade. Here is what erased it, and which profession took on the work.
500 – 1540
The barber-surgeon's Europe
As Latin Christendom's universities trained physicians in theory and diagnosis but rarely let them touch blood, the actual cutting — bloodletting, tooth-pulling, amputation, lancing boils — fell to barbers, who already owned sharp blades and steady hands. Guilds slowly organized the trade through the medieval centuries, from local barber-surgeon fraternities to London's 1540 Company of Barber-Surgeons, while the Islamic world's hospitals and translated Greek medical texts kept surgical knowledge more unified, and often more advanced, than in Europe.

Paré abandons boiling oil
Treating wounded soldiers at the Siege of Turin, French army surgeon Ambroise Paré ran out of the boiling oil then used to cauterize gunshot wounds and dressed the rest of his patients with egg yolk, rose oil and turpentine instead. Checking on them the next morning expecting the worst, he found the oil-treated men in agony and the others resting comfortably, and abandoned cautery with hot oil for good.

Hunter's ligation for aneurysm
At St George's Hospital in London, John Hunter treated a coachman's popliteal aneurysm by tying off the artery well above the damaged section with four separate ligatures, instead of the standard, frequently fatal amputation. The patient walked out six weeks later and returned to driving his cab; the "Hunterian ligation" remained standard practice for over a century.
Where that work lives now
The physician who operates to cure, from Sushruta's ancient rhinoplasty to today's robotic operating rooms, still alone with the decision at the table.
🫀 Surgeon →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.
c. 800–1200
The Islamic Golden Age systematizes medicine
Physicians in Baghdad, Cairo and Córdoba translated, corrected and expanded Greek medicine, built some of the earliest structured teaching hospitals, and produced encyclopedic texts — al-Razi's clinical case notes and Ibn Sina's Canon of Medicine chief among them — that Latin Europe would rely on for the next five centuries.

1347
The Black Death overwhelms Europe's physicians
Bubonic plague kills an estimated one-third of Europe's population over four years; academically trained physicians, working from humoral theory, can do little beyond urging quarantine and flight, exposing the gap between learned medical theory and any real ability to cure.
1619
The plague doctor's beaked mask appears
French physician Charles de Lorme designs a head-to-toe protective costume with a beak-shaped mask packed with aromatic herbs, worn against the belief that disease spread through 'bad air'; the outfit becomes the visual symbol of plague-era medicine across Europe.
1676
Sydenham publishes Observationes Medicae
London physician Thomas Sydenham argues diseases should be classified by their observed symptoms and course rather than humoral theory, distinguishing scarlet fever from measles and pioneering a cooling treatment for smallpox; the book stays a standard reference for two centuries.
1704
English apothecaries win the right to treat patients
The House of Lords rules for apothecary William Rose against the Royal College of Physicians, letting apothecaries prescribe as well as dispense medicine — the ruling that lets the apothecary evolve, over the following century, into Britain's general practitioner.
