Louis-Charles-Bonaventure-Alfred Bruneau (3 March 1857, in Paris – 15 June 1934, in Paris) was a French composer who played a key role in the introduction of realism in French opera. As a youth, Bruneau studied the cello at the Paris Conservatory, and played in the Pasdeloup orchestra. He soon began to compose, writing a cantata, Genevieve de Paris while still a young man. In 1884 his Ouverture heroique was performed, followed by the choral symphonies, Léda (1884), La belle au bois dormant (1886). In 1887, he produced his first opera, Kérim.
