Ray Dolby
Co-founder 1965Background
Ray Dolby was a brilliant young engineer who joined Ampex Corporation straight out of high school and played a pivotal role in the development of the first practical videotape recorder. His founding philosophy was centered on the radical idea that the pervasive, hissing noise of analog magnetic tape could be eliminated through advanced electronic signal processing, a problem that the entire audio industry had accepted as a physical limitation. Dolby's specific decision to leave Ampex, earn a Ph.D. at Cambridge, and found his own company in London to solve this exact problem defined the company's technological trajectory and its ultimate dominance in the global entertainment industry.
Role at Dolby Laboratories, Inc.
Dolby Laboratories possesses a technical, influential founding story, rooted not in Silicon Valley software coding, but in the complex, analog physics of sound recording and noise reduction. The company was founded in 1965 in London, England, by Ray Dolby, a brilliant, accomplished American physicist and engineer. Dolby was a prodigy; he began working for Ampex (the legendary pioneer of magnetic tape recording) while he was still in high school, playing a role in the development of the first practical video tape recorder. He later earned a PhD in physics from Cambridge University. While working in India as an United Nations advisor in the early 1960s, Dolby became frustrated with the inherent flaw in all magnetic tape recording: 'tape hiss.' The analog recording process introduced an amount of high-frequency background noise that ruined high-fidelity music reproduction. Returning to London, he founded Dolby Laboratories with a foundational, complex invention: Dolby A-type noise reduction. His brilliant algorithm essentially amplified low-volume sounds during recording and then compressed them during playback, eliminating the background hiss without altering the actual music. While his first product was expensive (used exclusively by professional recording studios like Decca and Abbey Road), his foundational masterstroke occurred in 1968 with the invention of Dolby B. This was a significantly simplified version designed specifically for consumer cassette tapes. He licensed this technology to electronics manufacturers, altering the economics of the music industry by making the cheap, portable cassette tape a viable format for high-fidelity music. Ray Dolby transformed his understanding of physics into an invisible, indispensable standard that changed how the world experiences sound.
