Ruggero Leoncavallo was an Italian opera composer. His two-act work Pagliacci remains one of the most popular works in the repertory, appearing as number 20 on the Operabase list of the most-performed operas worldwide. The son of a police magistrate, Leoncavallo was born in Naples on 23 April 1857. As child he moved with his father in the town of Montalto Uffugo in Calabria where Leoncavallo lived during his adolescence. He later returned to Naples and was educated at the city's San Pietro a Majella Conservatory. After some years spent teaching and in ineffective attempts to obtain the production of more than one opera, he saw the enormous success of Pietro Mascagni's Cavalleria rusticana in 1890, and he wasted no time in producing his own verismo hit, Pagliacci.
