(b Karlsruhe, 22 Jan 1901; d Vienna, 30 Nov 1972). Austrian composer of German birth. He moved to Vienna in 1921 and studied with Schoenberg and Berg, whom he followed in a long phase of atonal expressionism (e.g. in Kubiniana for piano, 1950) until in 1957 he became as absolute a serialist as Webern. His works include orchestral pieces but comprise mostly chamber music, sometimes with voice.
