André Caplet (23 November 1878 – 22 April 1925) was a French composer and conductor now known primarily through his orchestrations of works by Claude Debussy.He exhibited an unusual talent and originality during his musical education, and won the Prix de Rome in 1901 ahead of Maurice Ravel. He became a close friend of Claude Debussy, sometimes serving as translator, and he orchestrated part of Debussy's Le Martyre de saint Sébastien. He also collaborated with Debussy in the orchestration of La boîte à joujoux. In 1911, Caplet prepared an orchestration of Debussy's Children's Corner, which, along with his orchestration of Clair de lune from the Suite bergamasque is probably the most widely performed and recorded example of his work.
