was a French composer and the first female winner of the Prix de Rome composition prize. Her older sister was the noted composer and composition teacher Nadia Boulanger.
in 1912, Boulanger competed in the Prix de Rome but during her performance she collapsed from illness. She returned in 1913 at the age of 19 to win the composition prize for her cantata Faust et Hélène, becoming the first woman to win the prize. The text was written by Eugene Adenis based on Goethe's Faust.The cantata had many performances during her lifetime. Because of the prize, she gained a contract with the publisher Ricordi.
Nadia Boulanger had given up entering the Prix de Rome after four unsuccessful attempts and focused her attention on her role as assistant in Henri Dallier's organ class at the Conservatoire, where Lili studied harmony, counterpoint and composition with Paul Vidal and Georges Caussade, under the Conservatoire's Director Gabriel Fauré—the last of whom was greatly impressed by her talents and frequently brought songs for her to read. Boulanger was greatly affected by the 1900 death of her father; many of her works touch on themes of grief and loss. Her work was noted for its colorful harmony and instrumentation and skillful text setting. Aspects of Fauré and Claude Debussy can be heard in her compositions, and Arthur Honegger was influenced by her innovative work.
According to Caroline Potter, “The two sisters were both influenced by Debussy, and it appears they had similar literary tastes to the elder composer. Both sisters set poems by Maurice Maeterlinck, who was the author of the play Pelléas and Mélisande and also of Princesse Maleine; in February 1916, Maeterlinck authorized Lili to set the latter play as an opera. Allegedly, Lili had almost completed the opera before her death, though only the short score of act 1, scene 2, two versions of the libretto, and a sketchbook have survived."
