During the 1920's, after his opera Polypheme had won the Premier Prix du Concours musical de la Ville de Paris, and premiered in Paris during the 1922-23 operatic season, Jean Cras' became as much a household name as Maurice Ravel's. Part of this dissertation will attempt to explain why he was forgotten during the half-century between 1935 and 1985 [TRUNCATED] / 2031-01-01
