Ernst Haas (March 2, 1921, Vienna – September 12, 1986, New York) was an Austrian artist and influential photographer noted for his innovations in color photography, experiments in abstract light and form, and as a member of the Magnum Photos agency.
Haas moved to New York City and in 1953 produced a 24-page, color photo essay on the city for Life, which then commissioned similar photo spreads on Paris and Venice. By 1958 he was considered one of the top ten photographers in world by Popular Photography magazine. In 1962, the Museum of Modern Art mounted a one-man show of Haas' color photos. Haas' first photo book, Elements, was published the next year.
