Distinguished cinematographer of Hungarian parentage who began his career in Germany in the 1920s. Mate shot several films for Carl Theodor Dreyer, notably the dream-like masterpiece "Vampyr" (1932), before moving to Hollywood in 1934. His expressionist sensibility redeemed several lesser films, like Tay Garnett's "Professional Soldier" (1935), as well as making significant contributions to classics such as Charles Vidor's "Gilda" (1946). Mate turned to directing in 1947, with results ranging from the highly competent to the forgettable; his most famous directorial effort is the riveting 1949 noir standard "D.O.A".
