Darius Milhaud, (born Sept. 4, 1892, Aix-en-Provence, France—died June 22, 1974, Geneva, Switz.), a principal French composer of the 20th century known especially for his development of polytonality (simultaneous use of different keys).
Born of a Provençal Jewish family, Milhaud studied under Paul Dukas and Vincent d’Indy at the Paris Conservatory. He was grouped by the critic Henri Collet with the young composers whom Collet called Les Six. In 1940 he became professor at Mills College, Oakland, Calif. After 1947 he taught at the Paris Conservatory. In his later years he suffered from crippling arthritis, but he continued to compose and conduct.
