(b Reims, bapt. 22 Jan. 1649; d Versailles, 17 July 1709). French composer. By 1651 he had moved to Paris, and in 1677 became Lully's secretary. At the same time he was conductor at the Opéra, and six years later obtained the post of sous-maître in the royal chapel. He was appointed compositeur de la musique de la chambre in 1685 and maître de la musique and maître des pages there in 1696. After Lully's death in 1687 Collasse began composing operas on his own account, but with relatively little success. For a short time he managed an opera house in Lille, but it burnt down in 1700. His most successful work was Thétis et Pélée (1689), a tragédie lyrique notable for its vivid depiction of a storm in Act II. He was much in demand for occasional music but died in poverty, ruined by his attempts to find the philosopher's stone.
