(born 1 March 1841 in Novi Ligure, Italy, died 9 October 1907 in Milan), Italian composer and conductor. Marenco made an early debut as a composer with Lo Sbarco di Garibaldi a Marsala (Garibaldi's Arrival in Marsala) at the Teatro Doria in Genoa; he also played the violin and the bassoon during the performance. Afterward Marenco resumed his studies and toured as a violinist. In 1873 he became first violinist and director of ballet music at La Scala Ballet in Milan, serving in that capacity for seven seasons. He composed three operas and two operettas, but his name is most closely linked with the composition of ballets, particularly in collaboration with choreographers Luigi Manzotti, Antonio Pallerini, and Ferdinando and Giovanni Pratesi, on large historical or allegorical themes, providing many opportunities for lavish displays involving large numbers of dancers.
