Hiller, former professor of chemistry and music, died Jan. 26 at Niagara Lutheran Nursing Home, Buffalo, N.Y. He was 69. Hiller received bachelor's, master's and doctoral degrees in chemistry from Princeton University and studied music theory and composition with composers Roger Sessions and Milton Babbitt. He played clarinet and saxophone and took part in concerts and managed a college dance band. He worked as a research chemist for DuPont in Waynesboro, Va., from 1947 to 1952. His work in cellulose chemistry led to the discovery of a method of dying acrylic fibers, such as Orlon. After an extended trip to Europe, Hiller joined the UI chemistry department, first as a researcher in computer applications and then as an assistant professor. While at the UI, he received a master's degree in music and performed his first experiments in composing music with computers. In collaboration with Leonard Isaacson, he wrote "Illiac Suite for String Quartet" on the UI's Illiac I computer. The piece is considered the first significant work of computer music. He joined the School of Music faculty in 1958. During the next 10 years, he built an experimental music studio and developed a cooperative research program with the electrical engineering department in electronics, computers, music and acoustics. His last electronic composition while at the UI was "HPSCHD" for one to seven harpsichords and one to 51 tapes, a multimedia production composed in collaboration with John Cage. The New York Times called its 1969 premiere "the multimedia event of the decade." Hiller joined the University of Buffalo faculty in 1968 as a professor of composition and co-director with Lukas Foss of the Center for the Creative and Performing Arts. Hiller, Foss and Allen Sapp were instrumental in making Buffalo a center for serious avant-garde music in the late 1960s. In 1974, he became the director of the Experimental Studio at Buffalo, at that time one of the few centers for digital-to-analog sound synthesis. In 1980, he became the Birge-Cary Professor of Music at the University of Buffalo. He retired in 1990. Survivors include his wife, Elizabeth; a son; and a daughter. Doris B.
