Rudolf Friml (December 7, 1879 – November 12, 1972) was a composer of operettas, musicals, songs and piano pieces, as well as a pianist. After musical training and a brief performing career in his native Prague, Friml moved to the United States, where he became a composer. His best-known works are Rose-Marie and The Vagabond King, each of which enjoyed success on Broadway and in London and were adapted for film.
Born in Prague, at that time part of the Austro-Hungarian Empire and now capital of the Czech Republic, Friml showed aptitude for music at an early age. He entered the Prague Conservatory in 1895, where he studied the piano and composition with Antonín Dvořák. Friml was expelled from the conservatory in 1901 for performing without permission. In Prague and later in America he composed and published songs, piano pieces and other music, including the prize-winning set of songs, Pisne Zavisovy. The last of these, Za tichych noci, later became the basis for a famous film in Nazi-occupied Czechoslovakia in 1941.
