Born in Pittsburgh, Pennsylvania, Burt Glinn served in the United States Army between 1943 and 1946, before studying literature at Harvard University, where he edited and photographed for the Harvard Crimson college newspaper.
From 1949 to 1950, Glinn worked for LIFE magazine before becoming a freelancer. He became an associate member of Magnum in 1951, along with Eve Arnold and Dennis Stock – the first Americans to join the young photo agency – and a full member in 1954.
