Goldmark, Peter Carl (redirected from Goldmark)

Goldmark, Peter Carl, 1906–77, Hungarian-American engineer, b. Budapest. He studied at the Univ. of Vienna (B.S., 1929, Ph.D., 1931); worked for a radio company in England (1931–33). After emigrating to the United States (1933), he worked as a construction engineer until joining the Columbia Broadcasting System (CBS) in 1936. There he developed the first commercial color television system, 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 Although initially approved by the Federal Communications Commission, it was later superseded by an all-electronic color system that was compatible with black-and-white sets.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 developed the 33 1-3 LP phonograph that greatly increased the playing time of records. He also developed a scanning system used by the Lunar Orbiter spacecraft in 1966 to transmit photographs to the earth from the moon.

Goldmark, Peter Carl

(born , Dec. 2, 1906, Budapest, Hung.—died Dec. 7, 1977, Westchester county, N.Y., U.S.) Hungarian-U.S. engineer. He earned a doctorate from the University of Vienna before immigrating to the U.S. in 1933. From 1936 to 1972 he worked at the Columbia Broadcasting System Laboratories. In 1940 he demonstrated the first commercial colour-television system; based on a rotating three-colour disk, his system found wide application in closed-circuit television for industry, medical institutions, and schools because his camera was much smaller, lighter, and easier to maintain than those that eventually came to be used in commercial television. In 1948 he introduced the long-playing (LP) phonograph record, which revolutionized the recording industry. In 1950 he developed the scanning system that would allow the U.S. Lunar Orbiter spacecraft (launched in 1966) to relay photographs 238,000 mi (380,000 km) from the Moon to Earth.
