Donald "Don" Buchla (April 17, 1937 – September 14, 2016) was an American pioneer in the field of sound synthesizers, releasing his first units shortly after Robert Moog's first synthesizers. However, his instrument was arguably designed before Moog's. He studied physics, physiology, and music at UC Berkeley, graduating in 1959 as a physics major. Buchla formed his electronic music equipment company, Buchla and Associates, in 1962 in Berkeley, California. He was commissioned by composers Morton Subotnick and Ramon Sender, both of the San Francisco Tape Music Center, to create an electronic instrument for live performance. Buchla began designing his first modules for the Tape Music Center in 1963.
