Auber, Daniel-François-Esprit, 1782-1871, French operatic composer. His greatest successes resulted from his collaboration with the librettist Scribe. Their first success together was Le Maçon (1825), and among the long succession that followed were Fra Diavolo (1830), Le Domino noir (1837), and La Part du diable (1843), witty, tuneful, sophisticated works that were very popular in their time. La Muette de Portici (1828, also known as Masaniello) was the model of the French grand opera of the 1830s.
