new audience. It revived Lehár's flagging career as a composer of operetta. In the future, Lehár composed a number of operettas with roles written specifically for Richard Tauber, including Paganini (1925, although he was unavailable for the Vienna premiere, and first sang it in Berlin in 1926), Der Zarewitsch (1927), Friederike (1928), The Land of Smiles (1929) with the famous aria "Dein ist mein ganzes Herz", Schön ist die Welt (1930), and Giuditta (1934). The hit songs usually occurred in the second act and were informally known as Tauberlieder. Tauber appeared in a number of films, both in Germany and later in England. He provided a 'voice-over', singing the title song in the otherwise silent film I Kiss Your Hand, Madame (1929). When in Vienna, Tauber also conducted at the Theater an der Wien, and it was here in 1924 that he met the soprano Carlotta Vanconti who soon divorced her Italian husband and married Tauber on 18 March 1926. They separated in 1928 and divorced later the same year in Berlin. The divorce was recognised, however, only in Germany. In 1929 he met Mary Losseff at Rudolf Nelson's review in Berlin. They lived together for about five years. Losseff became his muse; it was for her that he wrote Der singende Traum. Losseff's career ended when she became an alcoholic, but Tauber remained her lifelong friend and supported her until his death. In 1931, Tauber made his London debut in operetta, and London appearances became a regular event; he also toured the United States in this year. In 1933, Tauber was assaulted in the street by a group of Nazi Brownshirts because of his Jewish ancestry, and he decided to leave Germany for his native Austria, where he continued to sing at the Vienna State Opera right up to the Anschluss in March 1938. In the mid-1930s, he made several musical films in England, and at the premiere of her film Mimi in April 1935, he met the English actress Diana Napier (1905–1982); they were married on 20 June 1936, only after protracted legal proceedings to secure an Austrian divorce from Vanconti. Napier appeared in three of his British films: Heart's Desire (1935), Land Without Music and Pagliacci (both 1936). Later career In 1938, he made his London operatic debut in Die Zauberflöte under Sir Thomas Beecham. Earlier that year, the Nazi government of Germany annexed Austria and Tauber
