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

In 1941, Lange was awarded a Guggenheim Fellowship for excellence in photography. After the attack on Pearl Harbor, she gave up the prestigious award to record the forced evacuation of Japanese Americans to relocation camps, on assignment for the War Relocation Authority (WRA). She covered the rounding up of Japanese Americans and their internment in relocation camps, highlighting Manzanar, the first of the permanent internment camps. To many observers, her photograph of Japanese-American children pledging allegiance to the flag shortly before they were sent to internment camps is a haunting reminder of this policy of detaining people without charging them with any crime or affording them any appeal.
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.
