Landowski's greatest musical influence was Arthur Honegger. His entire output includes five symphonies, several concertos (notably two for piano and one each for bassoon, for cello, for flute, for trumpet, for trombone), operas as well as a Mass and bears testimony to Honegger's impact. Landowski went on to write a biography of his mentor.
Between the 1940s and the 1960s, Landowski composed the scores for several dozen films, most notably Gigi (1949).
Landowski eschewed the avant-garde approaches to music of his contemporaries, preferring a more conservative style. In 1966, France's Cultural Affairs minister André Malraux appointed Landowski as the ministry's director of music, a controversial appointment made in the teeth of opposition from the then ascendant modernists, led by Pierre Boulez.
He died in hospital in Paris in 1999, aged 84.
