Dorothea Lange’s photos of the incarceration of Japanese Americans went largely unseen for decades.

US President Franklin D. Roosevelt passed Executive Order 9066 in February 1942 — two months after Japan’s bombing of the US Navy base at Pearl Harbor. It empowered the US army to designate strategic “military areas” from which any and all people deemed a threat could be forcibly removed. This began a process of placing 120,000 Japanese Americans in concentration camps during World War II.

To control the narrative around the removal, the government created a new department, the War Relocation Authority, and hired photographers to document the process. One of those photographers was Dorothea Lange, who had become famous during the 1930s for her Great Depression photographs for the Farm Security Administration.

Her images featured Japanese-American people in the weeks, days, and hours leading up to their incarceration in the camps, and captured expressions of dignity, resolve, and fear.

Most of Lange’s candid photos of the removal process weren’t approved for publication by the War Relocation Authority and were “impounded” for the duration of the war. They weren’t seen again widely until 1972, when her former assistant pulled them from the National Archives for a museum exhibit about the incarceration of Japanese Americans, called Executive Order 9066.

The photos became part of a redress movement for Japanese Americans in the 1970s and 1980s, which ultimately resulted in the Civil Liberties Act of 1988, a bill that approved reparations for survivors of the camps.
