Peter Carl Goldmark  was a Hungarian-born physicist and engineer who later became a U.S. citizen, is best known for his invention of the long-playing record, commonly known as the LP. It revolutionized the recorded music industry and dominated sales for 40 years. Spending most of his career as an engineer at CBS, he also contributed to the development of color television, photocopying, audio cassettes, and the video cassette recorder. Peter Goldmark was born on December 2, 1906 in Budapest, Hungary. He studied physics at the University of Vienna, where he received his BS in 1929 and his PhD in 1931, and began his career working for a radio company in England. In 1933, he emigrated to the United States and worked as a construction engineer until 1936, when he joined CBS, or Columbia Broadcasting System, as Chief Engineer of the Television Department. Goldmark can also be considered the father of video recording. With the goal of producing a tool for educational media storage, he developed a system called electronic video recording (EVR). This futuristic home video playback device used reels of film stored in plastic cassettes to electronically store audio and video signals, and was first announced in 1967. A B&W prototype was demonstrated in 1969, but the invention floundered when it proved to be difficult and costly to manufacture.[3] On November 22, 1977, President Jimmy Carter presented Goldmark with the National Medal of Science. He died in an automobile accident on December 7, 1977
