French composer; the younger sister of Nadia Boulanger. She achieved a great deal as a composer before her early death at the age of 24. In 1912 she entered the Paris Conservatory as a composition student for Paul Vidal. At age 19 she became the first woman to win the most prestigious composition prise of the day, the Prix de Rome, for her cantata Faust et Hélène. She suffered from Crohn’s disease for almost her entire life and could work only sporadically. Her music is operatic; she used somber, dark keys and used brass frequently. Influences from Fauré and Debussy are audible.
