Timeline of Early Computer Music at Bell Telephone Laboratories, Incorporated

Innovative contributions to computer music software and hardware were made at Bell Telephone Laboratories, Incorporated (BTL) during the 1960s. The justification for this work was its potential application to the synthesis of human speech for telephone applications. Computer music was a sideline to other research being performed and was not a full-time assignment. A timeline of these innovations and contributions is presented here, with references to documentation.

Many of the people who performed this early work went on to do other things at other institutions. John R. Pierce left Bell Labs in 1971 to go to the California Institute of Technology, then to Jet propulsion Laboratory, and ultimately in 1980 to Stanford University. Max V. Mathews retired from Bell Labs and joined Pierce at Stanford as professor of music in 1987. Richard Moore, after earning a doctorate in electrical engineering from Stanford University, became a professor in computer music at the University of California at San Diego in 1979. There were many composers and musicians who visited Bell Labs to learn about the work being done there, including the conductors Hermann Scherchen and Leopold Stokowski. Jean-Claude Risset, Emanuel Ghent, Laurie Spiegel, and Charles Dodge are some of the composers who visited Bell Labs and used the computer facilities there for their compositions.
