Brother to Magnum co-founder Robert Capa, Cornell Capa first discovered a passion for photography while helping to develop prints for his brother, as well as for Henri Cartier-Bresson and David “Chim” Seymour. Driven by a humanitarian impulse, Capa referred to himself and other like-minded image-makers as “concerned photographers”: photographers who aim not just to document the world around them but to change it for the better.
