Friml, (Charles) Rudolf

(born Dec. 7, 1879, Prague —died Nov. 12, 1972, Hollywood, Calif., U.S.) Czech-born U.S. composer. He studied under Antonín Dvorák, and he immigrated to the U.S. in 1906. In 1912, replacing Victor Herbert, he composed the highly successful operetta The Firefly (with Otto Harbach). The next major success of his approximately 30 operettas, Rose Marie (1924; with “Indian Love Call”), was followed by The Vagabond King (1925; with “Song of the Vagabonds” and “Some Day”) and The Three Musketeers (1928), among the last operettas to enjoy popular success.
