Richard John Dufallo (30 January 1933 in Whiting, Indiana – 16 June 2000 in Denton, Texas) was an American clarinetist, author, and conductor with a broad repertory. He is most known for his interpretations of contemporary music. During the 1970s, he directed contemporary music series at both Juilliard and the Aspen Music Festival, where he succeeded Darius Milhaud as artistic director of the Conference on Contemporary Music. He was influential at getting American works accepted in Europe, and gave the first European performances of works by Charles Ives, Carl Ruggles, Jacob Druckman, and Elliott Carter as well as younger composers like Robert Beaser. Dufallo, as conductor, also premiered numerous works by European composers, including Karlheinz Stockhausen, Sir Peter Maxwell Davies, and Krzystof Penderecki. He was a former assistant conductor of the New York Philharmonic, and worked closely with Leonard Bernstein from 1965 to 1975. He also served as associate conductor of the Buffalo Philharmonic.
