Parker, Horatio William, 1863–1919, American composer, b. Auburndale, Mass.; pupil of Rheinberger in Munich. He was an organist and choirmaster in Boston and New York City and taught at the National Conservatory, New York. In 1894, Parker became the first chairman of the music department at Yale, a position he held until his death. He composed for the stage, for orchestra, and for organ, but he is remembered as a writer of church music in the style of late German romanticism.
