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.
The perspectivist no longer exists as a living trade. Here is what erased it, and which profession took on the work.
c. 1750–1900
Academies, iron and the licensed profession
Architecture schools and professional bodies — the Royal Institute of British Architects (1834) and the American Institute of Architects (1857) among them — turned a loose trade into an organized profession with exams, ethics and journals, while new materials like cast iron and plate glass, seen at Joseph Paxton's Crystal Palace in 1851, expanded what could be built. In 1897 Illinois passed the first US law making 'architect' a legally licensed title.
What else was happening then
1897
Illinois licenses architects by law
Illinois passes the first architectural licensing law in the United States, making 'architect' a legally protected title for the first time and setting the model other states adopt over the next two decades.
1919
The Bauhaus opens in Weimar
Walter Gropius founds the Bauhaus, merging architecture, craft and industrial design in one curriculum; closed by Nazi pressure in 1933, its faculty scatter abroad and carry modernism to the rest of the world.
1982
AutoCAD moves design onto screens
Autodesk releases AutoCAD for desktop computers, and computer-aided drafting begins replacing the drafting board over the following two decades — the first step toward today's fully digital practice.
1997
Bilbao debuts computed form
Frank Gehry's Guggenheim Museum Bilbao opens with a titanium skin modeled in the aerospace software CATIA, proving computationally derived, non-standard geometry could be built on budget — the start of mainstream parametric design.
Where that work lives now
Designs buildings that must stand, meet code, please a client and cost the right amount — then carries legal responsibility if they don't.
