Tullio Serafin was a leading Italian opera conductor with a long career and a very broad repertoire who revived many 19th-century bel canto operas by Bellini, Rossini and Donizetti to become staples of 20th-century repertoire. He had an unparalleled reputation as a coach of young opera singers and famously harnessed and developed Maria Callas's considerable talents.\r \r Born in Rottanova (Cavarzere), near Venice, and trained in Milan, he played viola in the Orchestra of La Scala, Milan under Arturo Toscanini, later being appointed Assistant Conductor. He took over as Musical Director at La Scala when Toscanini left to go to New York, and served 1909-1914, 1917–1918, and returned briefly after the Second World War, 1946 -1947.\r \r He joined the conducting staff of the Metropolitan Opera in 1924, and remained for a decade, after which he became the artistic director of the Teatro Reale in Rome. During his long career he helped further the careers of many important singers, including Rosa Ponselle, Magda Olivero, Dame Joan Sutherland, and Callas, with whom he made several recordings.
