Peter Carl GoldmarkBorn 2 Dec 1906; died 7 Dec 1977 at age 71.American engineer (naturalized 1937). While working for Columbia Broadcasting System (CBS), he developed the first commercial color television system (1936), which used a rotating three-color disk. Although initially approved by the Federal Communications Commission, it was later superseded by an all-electronic color system that was compatible with black-and-white sets. Goldmark also developed the 33-1/3 LP phonograph that greatly increased the playing time of records, which revolutionized the recording industry. He also pioneered in video cassette recording, and developed a scanning system used by the Lunar Orbiter spacecraft in 1966 to transmit photographs to the earth from the moon. |
