Who was Dorothea Lange, and what is this comic about?

Dorothea Lange (1895–1965) was verified through Britannica, PBS American Masters, and MoMA. Britannica confirms her birth and death dates, her standing as an American documentary photographer, Migrant Mother, Depression-era migrant-worker work, and the late MoMA retrospective context. PBS confirms the childhood polio in 1902 that left a lifelong limp and her death from inoperable esophageal cancer on October 11, 1965 while preparing a major MoMA retrospective. MoMA confirms the enduring legacy of her Resettlement Administration/Farm Security Administration photographs documenting the Great Depression, rural poverty, and social engagement. Her worth is witness: she made public suffering visible as human evidence rather than abstraction.
