In 1929, photographer and avant-garde filmmaker Ralph Steiner (1899-1986) came to Yaddo to further explore and refine his visionary photographic philosophies. The next year he would found, with director Paul Strand, the Film and Photo League, a radical organization of filmmakers and photographers that created politically-committed newsreels and photos in an intentionally primitive style to call attention to the plight of workers. While this, and subsequent groups founded by Steiner, fractured along ideological lines, Steiner continued to collaborate with other artists on nearly all of his major worksâseemingly in the model of inclusive interdisciplinarity he had learned at Yaddo. In 1939 Steiner worked with such talents as writer and director Pare Lorentz urban philosopher Lewis Mumford, director Willard Van Dyke, and composer and former Yaddo guest Aaron Copland to produce a film entitled The City for the 1939 World's Fair. It was the product of the very collaboration and cooperation it advocated, and to this day it remains among the most accomplished and passionate filmic arguments for social justice in America.
