Who is Langer's experimental subject?

As a photographer for the Agricultural Safety Administration, Langer traveled to 22 states in the United States and took many photos reflecting the tragic scene of the Great Migration. Her own disability makes her more sympathetic to the suffering of others and closer to the subject. She photographed the recipients of relief, the homeless sleeping outside the unemployment shelter ... "People Waiting for Relief" and "Seasonal Working Mothers" became classic works.
