Between 1933 and 1935, Lorena Hickok traveled across thirty-two states as a "confidential investigator" for Harry Hopkins, head of FDR's Federal Emergency Relief Administration. Her assignment was to gather information about the day-to-day toll the Depression was exacting on individual citizens. One Third of a Nation is her record, underscored by the eloquent photographs of Dorothea Lange, Walker Evans, and others, of the shocking plight of millions of unemployed and dispossessed Americans.
