George Rochberg
George Rochberg (July 5, 1918 – May 29, 2005) was an American composer of contemporary classical music. Long a serial composer, Rochberg abandoned the technique after his teenage son died in 1964, saying it had proved inadequate to express his grief and was empty of expressive power. By the 1970s, Rochberg's use of tonal passages in his music had provoked controversy among critics and fellow composers. A professor at the University of Pennsylvania until 1983, Rochberg chaired its music department until 1968. He became the first Annenberg Professor of the Humanities in 1978.
