Jon Howard Appleton (January 4, 1939 – January 30, 2022) was an American composer, an educator and a pioneer in electro-acoustic music. His earliest compositions in the medium, e.g. "Chef d'Oeuvre" and "Newark Airport Rock" (1967) 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) (sv) 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. He 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 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. Early life Appleton was born in Los Angeles, California, on January 4, 1939, to Jewish parents: Helen Jacobs Appleton (born in Philadelphia, 1908) and Charles Leonard Appleton (born Chaim Epelboim in Kishinev, Bessarabia, July 14, 1900). His mother was employed by Metro-Goldwyn-Mayer and his father by Twentieth Century Fox film studios. His father left his family the year Appleton was born and he spent his first years in Mrs. Bell's (an orphanage) and with his brother (Michael Charles Appleton, born 1932) at Palomar Military Academy. When he was six years old his mother married Alexander "Sasha" Walden (born in Ufa, Russia, in 1897), a double-bass player in the Los Angeles Philharmonic orchestra. He was the greatest musical influence in Appleton's young life seeing that he studied piano, encouraging him to compose music and taking him to multiple concerts. Appleton's parents were true believers in the Soviet Union and active members of the multiple left-wing organizations including the Communist party. In the 1950s both his parents were blacklisted by the House Un-American Activities Committee and
