Peter Carl Goldmark

Peter Carl Goldmark (born December 2, 1906 in Budapest , † December 7, 1977 in Port Chester , New York ) was a Hungarian- born American engineer who demonstrated the first successful color television and developed the long-playing record .

Live and act

When Peter Carl Goldmark was eight years old, his parents divorced. When his mother remarried, he moved with her to Vienna, where he finished his studies in 1926 and made his first experiences with televisions. He hoped to work with John Logie Baird later . After graduating, Peter Carl Goldmark moved to England to work for Pye Radio as a TV engineer. After working for two years as head of the television department, he moved to New York in 1933, where he worked as a consultant for numerous television and radio companies. In 1936 he accepted a position as chief engineer with Columbia Broadcasting System (CBS). At Columbia Records he worked on the long-playing record . From 1945 to 1948 he developed the filler-free compound (made of PVC and PV acetate), which reduced the noise of the panels; In addition, the speed could be reduced from 78 to 33⅓ min ⁻¹ . In 1948 Goldmark invented the plastic long-playing record, which soon replaced the shellac record.

The first attempts to broadcast color television in 1940 go back to him. During a postponed honeymoon with his second wife in Montreal in the spring of 1940, Peter Carl Goldmark attended a screening of the film Gone with the Wind in Technicolor. He was fascinated by the color images and quickly excited about the idea of ​​color images on the television. After returning to the United States, he set about creating a prototype color television. The result, which he called the Field Sequential System, made its demonstration debut in New York on August 29, 1940. It projected colored images of flowers, a red boat sailed into a sunset, and a girl chased a ball the system broadcast the first live color TV images on CBS's experimental channels. Images were filmed using a rapidly rotating three-color wheel and displayed using a similar device. Since the system was not adapted to work on the existing black and white televisions, it was too impractical for the communications committee to give final approval. So the system he proposed was not used at the time. After a brief interlude in a non-backward-compatible system at CBS and NBC, the decision was made in 1953 for NTSC , which was named after the committee of the same name, but is now used indirectly in single-chip DLP projectors (sequential color reproduction using a color wheel).

Goldmark also contributed to the development of photocopies, audio cassettes and the video recorder.

He was inducted into the National Inventors Hall of Fame for the development of the LP . Since 1967 he was a member of the National Academy of Engineering . In 1972 he was elected to the American Academy of Arts and Sciences and the National Academy of Sciences . In 1976 he received the National Medal of Science .

Private

In 1936 he married Muriel Gainsborough, but the marriage was short-lived and the couple divorced. He became a US citizen the following year. On January 12, 1940, he married Charlotte Frances Trainer; they had four children, Frances Massey, Peter Carl Jr., Christopher and Andrew. The marriage ended with divorce in 1954. Goldmark later married his secretary Diane Davis, with whom he had two children, Jonathan and Susan.
