David Szymin was born in 1911 in Warsaw into a family of publishers that produced works in Yiddish and Hebrew. His family moved to Russia at the outbreak of the First World War, returning to Warsaw in 1919.

After studying printing in Leipzig and chemistry and physics at the Sorbonne in the 1930s, Szymin stayed on in Paris. David Rappaport, a family friend who owned the pioneering picture agency Rap, lent him a camera. One of Szymin’s first stories, about night workers, was influenced by Brassaï’s Paris de Nuit (1932). Szymin – or ‘Chim’ – began working as a freelance photographer. From 1934, his picture stories appeared regularly in Paris-Soir and Regards. Through Maria Eisner and the new Alliance agency, Chim met Henri Cartier-Bresson and Robert Capa.

In 1947, along with Cartier-Bresson, Capa, George Rodger, and William Vandivert, he founded Magnum Photos. He was commissioned by UNICEF the following year to photograph Europe’s children in need. He went on to photograph major stories across Europe, Hollywood stars on European locations, and the emergence of the State of Israel. After Robert Capa’s death, he became the new president of Magnum. He held this post until 10 November 1956, when, traveling near the Suez Canal to cover a prisoner exchange, he was killed by Egyptian machine-gun fire.
