The RCA Mark II Sound Synthesizer (nicknamed Victor) was the first programmable electronic synthesizer and the flagship piece of equipment at the Columbia-Princeton Electronic Music Center. Designed by Herbert Belar and Harry Olson at RCA, it was installed at Columbia University in 1957. Consisting of a room-sized array of interconnected sound synthesis components, much of the design of the machine was contributed by Vladimir Ussachevsky and Peter Mauzey. The Mark II gave the user more flexibility and had twice the tone oscillators of its predecessor, the Mark I. The synthesizer was funded with a large grant from the Rockefeller Foundation.
