This app shows over 5,000 photographs taken by John Collier Jr. for the Farm Security Administration (FSA) and the Office of War Information (OWI) from 1941 to 1943.
An internet connection is required. You can view the photos in a grid, with the complete Library of Congress captions; one-by-one; or as a slideshow. You can also browse to the Library of Congress page for each photo and order prints, at very reasonable prices.
Collier was born in 1913, the son of John Collier Sr., who served as Commissioner of Indian Affairs from 1933 to 1945. The family spent much time in the Taos, New Mexico, area, and Collier Jr. made his home there in the 1930s. (About a thousand of the photos here were taken in New Mexico.) He was introduced to photography by Dorothea Lange when he, as a teenager, was apprenticed to her husband, painter Maynard Dixon.
