Landowski's greatest musical influence was Arthur Honegger. His entire output (including five symphonies, several concertos, operas and a Mass) 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.
