About Peter Carl Goldmark
Peter Carl Goldmark (born Péter Károly Goldmark; December 2, 1906 – December 7, 1977) was a Hungarian-American engineer who, during his time with Columbia Records, was instrumental in developing the long-playing microgroove 331⁄3 rpm phonograph disc, the standard for incorporating multiple or lengthy recorded works on a single disc for two generations. The LP was introduced by Columbia's Goddard Lieberson in 1948. Lieberson was later president of Columbia Records from 1956–1971 and 1973–1975. According to György Marx, Goldmark was one of The Martians. == Early life == Goldmark married Frances Trainer, whom he later divorced. Together they had four children; three sons: Peter Jr., Christopher, Andrew and one daughter: Frances. After divorcing Frances Trainer, Goldmark married Diane Davis and had two more children: Jonathan and Susan. == Career == Goldmark worked on televisions for a brief period for the Pye Radio and TV company in Cambridge before moving to the USA to work for CBS. In addition to his work on the LP record, Goldmark developed field-sequential color technology for color television while at CBS. The system, first demonstrated on August 29, 1940, and shown to the press on September 3 used a rapidly rotating color wheel that alternated transmission in red, green and blue. The system transmitted on 343 lines, about 100 less than a black and white set, and at a different field scan rate, and thus was incompatible with television sets currently on the market without an adapter. Although CBS did broadcast in color with the Goldmark system in 1950–1951, the "compatible color" technology developed for RCA and NBC (by a team led by Richard Kell, George H. Brown and others) was compatible with existing black and white TVs.
