Ernst Haas (1921–1986) is acclaimed as one of the most celebrated and influential photographers of the 20th century and considered one of the pioneers of color photography. Haas was born in Vienna in 1921, and took up photography after the war. His early work on Austrian returning prisoners of war brought him to the attention of Life magazine. He declined a job offer as staff photographer in order to keep his independence. At the invitation of Robert Capa, Haas joined Magnum in 1949, developing close associations with Capa, Henri Cartier-Bresson, and Werner Bishof.
