Ray Dolby, the engineer and inventor who helped revolutionize movie soundtracks, died at his home in San Francisco Thursday, September 12, 2013, at the age of 80.
Born in Portland, Ore., Dolby studied at Stanford and Cambridge Universities before founding Dolby Laboratories in London. The company (which he later moved to California) became an industry leader in audio technology -- creating and improving recording and reproduction systems for music and film studios, theaters, and home and car audio.
Much of the initial success was in Dolby’s nose reduction processes, which eliminated tape hiss from recordings and playback and improved the viability of tape cassettes for home audio.
Its greatest success, however, and what made the name Dolby recognizable to the vast public, was in bringing noise reduction to the movies, boosting dynamic range, and making sound as much a marketing component for cinemas in the 1970s and 1980s as visual effects.
