Composer Robert Linn, whose more than 80 works have been performed on six continents, died in Los Angeles on October 28 from complications of cancer. He was 74.

Linn was born in San Francisco and studied composition with Darius Milhaud, Halsey Stevens, Roger Sessions, and Ingolf Dahl. He was professor emeritus of the Thornton School of Music at the University of Southern California, where he taught for 33 years and was chairman of the composition department for nearly two decades before retiring in 1990.

Mr. Linn was the recipient of numerous awards from organizations such as ASCAP and the Macdowell Association, and his works have been performed by the San Francisco, Boston, and London Symphonies.

His 1990 Concerto for Piano and Orchestra No. 2, written for pianist John Perry, was a semifinalist in the Kennedy Center's Eric Friedheim Awards Competition and a finalist in the National Orchestra Association New Music Project.
