Magnum Photos

Magnum Photos is an international photographic cooperative owned by its photographer-members, with offices in Paris, New York City, London and Tokyo. It was founded in 1947 in Paris by photographers Robert Capa, David "Chim" Seymour, Maria Eisner, Henri Cartier-Bresson, George Rodger, William Vandivert, and Rita Vandivert. Its photographers retain all copyrights to their own work.

In 2010, MSD Capital acquired a collection of nearly 200,000 original press prints of images taken by Magnum photographers, which in 2013 it donated to the Harry Ransom Center. Provided by Wikipedia
