Born in New York City, Dan Weiner (1919-1959) studied painting at the Art Students League in 1937 and at Pratt Institute from 1939 to 1940. While at Pratt, he joined the Photo League. In 1940 he taught at the Photo League and opened an advertising studio. During World War II, while in the US Army Air Corps, he discovered the 35-millimeter camera. His experiments with small-format photography led him to close his studio in 1949 and dedicate himself full-time to photojournalism. Throughout the 1950s, with his wife, Sandra Weiner, also a photographer, he produced features for publications such as Collier's and Fortune. In 1956 he traveled to the Soviet Union, Romania, Czechoslovakia, and Poland to document lifestyles of people there; he planned to publish a book of those journeys, but was killed in a plane crash while on assignment in 1959. Weiner's photography, along with that of Robert Capa, Werner Bischof, Chim (David Seymour), Leonard Freed, and André Kertész, was included in the 1967 exhibition .
