According to Moog Music Inc., Moog was diagnosed with brain cancer in April and received radiation treatment and chemotherapy to help combat the disease. He is survived by his wife, Ileana, his five children, and the mother of his children, Shirleigh Moog.

The Moog synthesizer made a large and immediate impact on music when it was introduced in 1964. Moog received a Grammy Trustee Award for lifetime achievement in 1970.

"Bob has been such a huge inspiration to all of us," said Mike Adams, president of Moog Music, in a statement pasted on the company's Web site. "In losing him, we lose a creator, visionary and friend. He was someone who taught us well and he was proud of this company and its people. Bob shaped music in deep and meaningful ways by changing how music could be produced and ultimately, how it would sound."

Moog's family has established The Bob Moog Foundation, dedicated to the advancement of electronic music, in his memory.
