International photographic agency, founded with offices in New York and Paris in April 1947 by the photographers Robert Capa, Henri Cartier-Bresson, Chim, George Rodger (b 1908) and William Vandivert (1912-c. 1992). In the period after World War II, when illustrated news magazines flourished, Magnum became the most famous of picture agencies. This was initally due to the reputation of its founder-members, who had photographed the Spanish Civil War (1936-9) and World War II (three of them as correspondents for Life magazine). Its celebrity was sustained by the success of its work, the quality of the photographers it continued to attract and by the deaths while on assignment of Capa (the driving force behind Magnum), Chim and Werner Bischof, the first new member to be admitted.
