Mario Lanza
Mario Lanza was an American tenor of Italian ancestry, and an actor and Hollywood film star of the late 1940s and the 1950s. Lanza began studying to be a professional singer at the age of 16. After appearing at the Hollywood Bowl in 1947, Lanza signed a seven-year film contract with Louis B. Mayer, the head of Metro-Goldwyn-Mayer, who saw his performance and was impressed by his singing. Prior to that, the adult Lanza had sung only two performances of an opera.
