Oscar Hammerstein II, (born July 12, 1895, New York, New York, U.S.—died August 23, 1960, Doylestown, Pennsylvania), American lyricist, musical comedy author, and theatrical producer influential in the development of musical comedy and known especially for his immensely successful collaboration with the composer Richard Rodgers.
