Dorothea Lange’s Depression-era “Migrant Mother” photograph is an icon of American history. Behind this renowned portrait is the story of a family struggling against all odds to survive. Dust storms and dismal farming conditions force young Ruby’s family to leave their home in Oklahoma and travel to California to find work. As they move from camp to camp, Ruby sometimes finds it hard to hold on to hope. But on one fateful day, Dorothea Lange arrives with her camera and takes six photographs of the young family.
