Magnum Photos, since its inception in 1947, has been a cooperative of photographers at the forefront of reportage and documentary photography. Members have been key witnesses and interpreters of the world's events, and players and principals in the development of the medium. There are forty-four member photographers in Magnum, based in Europe, Asia, and the Americas, pursuing reportage stories, assignments, and other documentary projects. Magnum operates out of offices in New York, Paris, London, and Tokyo, with a network of other representatives around the word.
