Robert Moog added so much, changing rock music and classical and providing the tech that is at the basis of hip-hop. Most people gained their first grasp of the meaning of "synthesis" thanks to his "synthesizer".
He spent the early 1990s as a research professor of music at the University of North Carolina at Asheville before turning full-time to running his new instrument business, which was renamed Moog Music in 2002. Recent customers includes Nine Inch Nails, Pearl Jam, Beck, Phish, Sonic Youth and Widespread Panic.
A public memorial is scheduled for Wednesday in Asheville.
