In 1926, Marcel Dupré was appointed professor of organ performance and improvisation at the Paris Conservatoire, a position he held until 1954. In 1934, he succeeded Charles-Marie Widor as titular organist at St. Sulpice in Paris, a post he held until his death in 1971. He taught two generations of well-known organists such as Jehan Alain and Marie-Claire Alain, Jean-Marie Beaudet, Pierre Cochereau, Jeanne Demessieux, Rolande Falcinelli, Jean-Jacques Grunenwald, Jean Guillou, Jean Langlais, Carl Weinrich and Olivier Messiaen.
