Walker Evans did more to expand the art and language of documentary photography than any other photographer, influencing generations of image-makers. He created some of the most memorable images of social and photographic history, and is best-known for his direct, descriptive photographs of vernacular scenes—particularly those of rural America, made during the Great Depression while Evans was working for the Farm Security Administration. His work about three sharecropping families in the South resulted in the groundbreaking book, coauthored with James Agee, Let Us Now Praise Famous Men (1941).
