Dorothea Lange (1895-1965) became well-known for her documentary photography during President Franklin D. Roosevelt's "New Deal" in the 1930ies. She was hired by the Farm Security Administration (FSA) to document working and living conditions of migrant workers in California. Trained as portrait photographer in San Francisco she soon developed her own documentary style and discussed it vividly with other photographers like Willard Van Dyke, Ansel Adams or Edward Weston. This book traces back her career as documentary photographer, how she interacted with contemporaries, and poses the question if she really succeeded in approaching her subjects without influencing them (like she always claimed she would do). "Dorothea Lange - Her Approach To The Documentary Style During FDR's New Deal" is a personal portray of an extraordinary photographer and her social and professional environment.
