MEGAN THOMPSON:

Starting in the 1940s, Dickey Chapelle was one of America's first female photojournalists to go to war zones…from Panama to Vietnam. Life Magazine, National Geographic, and Reader's Digest all published her work.

Her first combat assignment, for the publisher of Women's Day, was during World War II. She covered the battles of Iwo Jima and Okinawa, where she photographed wounded soldiers on a hospital boat.

This photo – of an injured soldier waiting for medical treatment — was one of her most widely published.
