Peter Goldmark

LP Inventor

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 1956–71 and 1973–75. According to György Marx, he was one of The Martians.
