was an Italian violinist, composer and conductor.
Arditi was born in Crescentino, Piemonte, Kingdom of Sardinia. He began his musical career as a violinist, and studied music at the Milan Conservatory under Bernardo Ferrara (violin) and Nicola Vaccai (composition). He made his debut in 1843 as a director at Vercelli, and it was there that he was made an honorary member of the Philharmonic Academy. Arditi conducted opera throughout Italy and in 1846 travelled to Havana, Cuba to co-direct the opera orchestra there with the double bass player Giovanni Bottesini. Their company made long tours of America, and he subsequently moved there to conduct operas in New York, Philadelphia and other cities with the Max Maretzek Italian Opera Company until 1856. Then, following a visit to Constantinople, he decided to settle in London, but made several trips again to America with the Royal Italian Opera Company. He also conducted in Germany, and in other major European cities such as St. Petersburg, Vienna and Madrid. After 1885, he was in England, conducting at Covent Garden and in various prestigious theatres and promenade concerts in London's parks.
He died at Hove, near Brighton (England); he is buried in Hove Cemetery.
