Leo Delibes, the French composer, was born at St. Germain du Val in 1836, and was graduated at the Paris Conservatory, where he reached high distinction. His first work, written in 1855, was an operetta entitled "Deux Sous de Carbon;" but he did not make his mark until his "Maitre Griffard" was produced at the Theatre Lyrique in 1857. In 1865 he was appointed Chorus-master at the Opera, and there his real career began. His first great triumph was in ballet-music, which has ever since been his specialty. His first ballet, "La Source," was produced at the Opera, Nov. 12, 1865, and delighted all Paris. It was followed by a divertisement for the revival of Adam's "Corsaire" (1867), the ballet "Coppelia" (1870), a three-act opera "Le Roi l'a dit" (1873), and the exquisite ballet in three acts and five tableaux, "Sylvia" (1876), with which Theodore Thomas has made American audiences familiar. His opera "Lakme" was written in 1879.
