Francis Jean Marcel Poulenc (French pronunciation: (7 January 1899 - 30 January 1963) was a French composer and a member of the French group Les Six. He composed music in genres including art song, solo piano music, chamber music, oratorio, opera, ballet music, and orchestral music. Critic Claude Rostand, in a July 1950 Paris-Presse article, described Poulenc as "half monk, half delinquent" ("le moine et le voyou"), a tag that was to be attached to his name for the rest of his career.
