Luigi Arditi, an Italian violinist and composer, born at Crescentino in Piedmont, July 22, 1822. He received his musical education in the conservatory at Milan, and first made himself known in public concerts as a violinist in 1839. In 1841 his opera I Briganti was produced at Milan. In 1S51 he visited Havana and the United States, and was for several seasons conductor at the Italian opera houses in New York. While in that city he composed an opera entitled La Spia, the plot of which was based upon incidents in Cooper's novel "The Spy." To identify it as an American work, "Hail Columbia" was introduced as the finale. The opera was brought out at the New York academy of music March 24, 1856, but its merits did not entitle it to any great success. Shortly after this production Arditi went to London, where he became the leader of the opera at her majesty's theatre. His songs have met with a greater popularity than his more ambitious compositions.
