The government paid out-of-work artists to eat and accidentally helped launch American modern art. From the Public Works of Art Project that painted Coit Tower's murals to the WPA's Federal Art Project and its roughly 200,000 works, young unknowns like Pollock and de Kooning were on the payroll. Ansel Adams's parks project was a separate Interior commission.
Historians credit the project with helping seed Abstract Expressionism, but European émigrés, New York galleries and the war also mattered. Artist and artwork counts are round estimates, and Coit Tower is a PWAP project, not WPA.
