Roy Emerson Stryker (November 5, 1893 – September 27, 1975) was an American economist, government official, and photographer. He headed the Information Division of the Farm Security Administration (FSA) during the Great Depression, and launched the documentary photography program of the FSA. It hired photographers to travel across the United States and document people in different areas and settings as part of showing the state of people in rural areas in those years. Specific projects were conceived to help assess effects of government programs.
