The forerunner of the Columbia-Princeton Electronic Music Center was a studio founded in the early 1950s by Columbia University professors Vladimir Ussachevsky and Otto Luening, and Princeton University professors Milton Babbitt and Roger Sessions. Originally concerned with experiments in music composition involving the new technology of reel-to-reel tape, the studio soon branched out into all areas of electronic music research. The Center was officially established with a grant from the Rockefeller Foundation in 1959 which was used to finance the acquisition of the RCA Mark II Sound Synthesizer from its owner, RCA.
