Magnum was founded in Paris in 1947 by H. Cartier-Bresson, R. Capa, and D. Seymour. Among its members are the best professional press photographers in Western Europe and America. In its early years, the agency held independent views and photographs by its members were noted for their antifascist and antiwar sentiments.
