George Rochberg was an American composer and educator whose work includes symphonies, concertos, string quartets and the opera The Confidence Man. He taught at the University of Pennsylvania from 1960 until 1983, serving as music department chair and later as Annenberg Professor of the Humanities. Earlier, he taught at the Curtis Institute of Music, where he had studied after service in World War II. His Violin Concerto became closely associated with Isaac Stern, who performed it repeatedly during the 1970s. Rochberg also worked in music publishing and wrote about compositional practice and musical expression. His honors included two Guggenheim Fellowships and membership in the American Academy of Arts and Letters.
