Dorothea Lange (1895-1965) was an American documentary photographer and photojournalist who is best known for her work for the Farm Security Administration (FSA) during the Great Depression. Not only did Lange and her colleagues photograph American poverty for the government, their work showed the human side to the plight of the American poor and also had a profound impact on the growth of documentary photography in the US. Lange is perhaps most famous for this iconic photograph of a migrant farm working mother and her children which she took in 1936.

During WWII, Lange documented the forced relocation of Japanese American citizens, and later served on the faculty of the California School of Fine Arts/San Francisco Art Institute. She also created the photo magazine Aperture. She continued her work documenting poverty and displacement in the US, and died of esophageal cancer at age 70.
