Accomplished French teacher, composer, and conductor, Nadia Juliette Boulanger was born on September 16, 1887, into a family of well-known musicians. Her paternal grandmother, Marie Julie Boulanger, sang for the Opéra-Comique, and her father, Ernest, was an esteemed pianist and professor at the Paris Conservatoire de Musique. Boulanger's younger sister, Lili (1893-1918), later became one of the most celebrated French female composers of her time, as well as the first woman to earn the prestigious Premier Grand Prix de Rome. She owed much to the guidance and direction of Nadia.
