Document 14: Jon Appleton: Jon Howard Appleton (born January 4, 1939) is an American composer and teacher who was a pioneer in electro-acoustic music. His earliest compositions in the medium, e.g. Chef d'Oeuvre and Newark Airport Rock attracted attention because they established a new tradition some have called programmatic electronic music. In 1970 he won Guggenheim, Fulbright and American-Scandinavian Foundation fellowships. When he was twenty-eight years old he joined the faculty of Dartmouth College where he established one of the first electronic music studios in the United States. He remained there intermittently for forty-two years. In the mid-1970s he left Dartmouth to briefly become the head of Elektronmusikstudion (EMS) in Stockholm, Sweden. In the late 1970s, together with Sydney Alonso and Cameron Jones he helped develop the first commercial digital synthesizer called the Synclavier. For a decade he toured around the United States and Europe performing the compositions he composed for this instrument. In the early 1990s he helped found the Theremin Center for Electronic Music at the Moscow Conservatory of Music where he continues to teach once a year. He has also taught at Keio University (Mita) in Tokyo, Japan, CCRMA at Stanford University and the University of California Santa Cruz. In his later years he has devoted most of his time to the composition of instrumental and choral music in a quasi-Romantic vein which has largely been performed only in France, Russia and Japan.
