History: The Great Depression By Dorothea Lange, 1939-1943, United States

Her images were so obviously critical that the Army impounded them. Today her photographs of the internment are available in the National Archives on the website of the Still Photographs Division, and at the Bancroft Library of the University of California, Berkeley.
In 1945, Lange was invited by Ansel Adams to accept a position as faculty at the first fine art photography department at the California School of Fine Arts (CSFA). Imogen Cunningham and Minor White joined as well.
In 1952, Lange co-founded the photographic magazine Aperture. Lange and Pirkle Jones were commissioned in the mid-1950s to shoot a photographic documentary for Life magazine of the death of Monticello, California and of the displacement of its residents by the damming of Putah Creek to form Lake Berryessa. The magazine did not run the piece, so Lange devoted one whole issue of Aperture to the work. The photo collection was shown at the Art Institute of Chicago in 1960.
In the last two decades of her life, Lange's health was poor. She suffered from gastric problems, including bleeding ulcers, as well as post-polio syndrome — although this renewal of the pain and weakness of polio was not yet recognized by most physicians.
