Dorothea Lange was an American photographer born in 1895 who is best known for her Depression-era work for the Farm Security Administration. Some of her most iconic photos included "The White Angel Breadline" from 1933 and "Migrant Mother" from 1936 which captured the struggles of migrant farm workers and helped shape understanding of the Great Depression. Lange believed photography could help people by documenting their lives and showing aspects that may otherwise be unseen. She is considered one of the greatest documentary photographers of the 20th century.
