In 1946 the Truman administration made a promise to striking coal miners: as part of a deal to resume work, the government would sponsor a nationwide survey of health and labor conditions in mining camps. One instrumental member of the survey team was photographer Russell Lee. Lee had made his name during the Depression, when, alongside Dorothea Lange and Walker Evans, he used his camera to document agrarian life for the Farm Security Administration (FSA). Now he trained his lens on miners and their families to show their difficult circumstances despite their essential contributions to the nation’s first wave of postwar growth.
