Renowned Polish photographer David Seymour (born Dawid Szymin) began his career in Paris in the 1930s and is best known for his images of the Spanish Civil War and for the UNICEF-commissioned project Children of War. With Henri Cartier-Bresson, Robert Capa, George Rodger, and William Vandivert, Seymour co-founded Magnum Photos and served as its president from 1954 until 1956, when, traveling near the Suez Canal to cover a prisoner exchange, he was killed by Egyptian machine-gun fire.
