After an intensive period of vocal training under
Carl Beines, Tauber made his public debut at a concert in
Freiburg on 17 May 1912. That same year, his father was appointed
Intendant of the Municipal Theater in
Chemnitz, which allowed him to arrange Tauber's debut as Tamino in
The Magic Flute on 2 March 1913. A few weeks later, on 16 April, Tauber performed the role of Max in
Der Freischütz. This performance was attended by of the
Dresden Opera, who had already offered Tauber a five-year contract starting on 1 August. The Count encouraged Tauber to take small roles with other companies to broaden his experience. During his tenure in Dresden, Tauber earned a reputation as an exceptionally quick learner. He mastered
Gounod's
Faust in 48 hours and learned
Bacchus in
Richard Strauss's
Ariadne auf Naxos overnight, astonishing Strauss, who conducted the performance in Berlin. This earned him the nickname "the SOS Tenor." In 1926, he rescued the German premiere of Puccini's
Turandot at the Staatsoper Dresden by learning the role of Calaf in three days after tenor Curt Taucher fell ill. After guest appearances at the
Wiener Volksoper in 1920, Tauber made his
Vienna State Opera debut on 16 June in
La bohème, stepping in for an indisposed
Alfred Piccaver. In 1922, he signed a five-year contract with the
Vienna State Opera and subsequently performed with the
Berlin State Opera. For many years, he divided his time between these two companies, spending four months with each, while reserving the remaining months for concerts, guest appearances with other companies, and international tours. Tauber sang tenor roles in numerous operas, including
Don Giovanni,
The Bartered Bride,
Tosca,
Mignon,
Faust,
Carmen, and
Die Fledermaus. He also appeared in modern works such as
Erich Korngold's
Die tote Stadt and
Wilhelm Kienzl's
Der Evangelimann. According to Daniel O'Hara's Tauber Chronology, he performed over 100 roles in opera and operetta. Although some critics looked down on his venture into operetta, it proved beneficial for Tauber, helping him gain a new audience and revitalizing Lehár's career as a composer of operetta. In the years that followed, Lehár composed several operettas with roles written specifically for Richard Tauber, including
Paganini (1925, although Tauber was unavailable for the Vienna premiere and first performed it in Berlin in 1926),
Der Zarewitsch (1927),
Friederike (1928),
The Land of Smiles (1929), which featured the famous aria "
Dein ist mein ganzes Herz",
Schön ist die Welt (1930), and
Giuditta (1934). The hit songs, typically in the second act, became informally known as
Tauberlieder. Tauber also appeared in several films, both in Germany and later in England. Notably, he provided a 'voice-over', singing the title song in the otherwise silent film
I Kiss Your Hand, Madame (1929). While in Vienna, Tauber also conducted at the Theater an der Wien, where, in 1924, he met the soprano Carlotta Vanconti. She soon divorced her Italian husband and married Tauber on 18 March 1926. They separated in 1928 and divorced later that same year in Berlin. However, the divorce was only legally recognized in Germany. In 1929, Tauber met
Mary Losseff at Rudolf Nelson's review in Berlin, and they lived together for about five years. Losseff became his muse, and it was for her that he composed
Der singende Traum. Although Losseff's career was cut short by alcoholism, Tauber remained her lifelong friend and supported her until his death. In 1931, Tauber made his London debut in operetta, and London performances became a regular part of his schedule. He also toured the United States that same year. In 1933, Tauber was attacked in the street by a group of
Nazi Brownshirts due to his
Jewish ancestry. Following the assault, he decided to leave Germany for his native Austria, where he continued to perform at the Vienna State Opera until the
Anschluss in March 1938. During the mid-1930s, Tauber made several musical films in England. In April 1935, at the premiere of the film
Mimi, he met the English actress
Diana Napier (1905–1982). After protracted legal proceedings to secure an Austrian divorce from Vanconti, they married on 20 June 1936. Napier appeared in three of his British films: ''
Heart's Desire (1935), Land Without Music, and Pagliacci'' (both 1936). ==Later career==
