The RCA Mark II Sound Synthesizer was the first programmable electronic music 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 synthesizer was funded with a large grant from the Rockefeller Foundation. Earlier 20th century electronic instruments such as the Telharmonium or the theremin were manually operated. The RCA combined diverse electronic sound generation with a music sequencer.
