In 1947, following the aftermath of the Second World War, four pioneering photographers founded a now legendary alliance. Combining an extraordinary range of individual styles into one powerful collaboration, Henri Cartier-Bresson, Robert Capa, George Rodger and David Seymour started, over a celebratory bottle of champagne, the longest running artists’ cooperative: The Magnum Photos agency. For over 75 years Magnum has documented most of the world’s major events, people and places. In short, when you picture an iconic image, but can’t think who took it or where it can be found, it probably came from Magnum.
