Final answer:
Dorothea Lange was a photojournalist known for her work during the Great Depression, capturing the struggles of American farmers and their families.
Step-by-step explanation:
The renowned photographer Dorothea Lange was a prominent figure during the Great Depression. Best known for her photograph "Migrant Mother, Nipomo, California", Lange depicted the harrowing effects of the Great Depression and the Dust Bowl on American farmers and families.
With her Hasselblad camera, Lange traveled through the Dust Bowl states capturing moving images of desolation that would later fuel government action to help the unemployed. Her work, including the emotionally charged image of Florence Thompson, a Cherokee woman with her children, became symbols of this era. Lange's photographs were a critical element in documenting the history and social circumstances of the 1930s in America.
