Charlotte "Lotte" Lehmann (February 27, 1888 – August 26, 1976) was a German soprano who was especially associated with German repertory. She gave memorable performances in the operas of Richard Strauss, Richard Wagner, Ludwig van Beethoven, Puccini, Mozart, and Massenet. The Marschallin in Der Rosenkavalier, Sieglinde in Die Walküre and the title-role in Fidelio are considered her greatest roles. During her long career, Lehmann also made more than five hundred recordings. Her performances in the world of Lieder are considered among the best ever recorded. 　　Lehmann was born in Perleberg, Province of Brandenburg. In 1926 she married Otto Krause, who died in 1939. 　　After studying in Berlin with Mathilde Mallinger, she made her debut at the Hamburg Opera in 1910 as a page in Wagner's Lohengrin. In 1914, she gave her debut as Eva in Die Meistersinger von Nürnberg at the Vienna Court Opera – the later Vienna State Opera –, which she joined in 1916. She quickly established herself as one of the company's brightest, most beloved stars in roles such as Elisabeth in Tannhäuser and Elsa in Lohengrin. She created roles in the world premieres of a number of operas by Richard Strauss, including the Composer in Ariadne auf Naxos in 1916 (later she sang the title-role in this opera), the Dyer's Wife in Die Frau ohne Schatten in 1919 and Christine in Intermezzo in 1924. Her other Strauss roles were the title-roles in Arabella and in Der Rosenkavalier (earlier in her career, she had also sung the role of Sophie; when she finally added the Marschallin to her repertoire, she became the first soprano in history to have sung all three female lead roles in Der Rosenkavalier). Her Puccini roles at the Vienna State Opera included the title-roles in Tosca, Manon Lescaut, Madama Butterfly, Suor Angelica, Turandot, Mimi in La Bohème and Giorgetta in Il Tabarro. In her 21 years with the company, Lehmann sang more than fifty different roles at the Vienna State Opera, including Marie/Marietta in Die tote Stadt, the title-roles in La Juive by Fromental Halévy, Mignon by Ambroise Thomas, and Manon by Jules Massenet, Charlotte in Werther, Marguerite in Faust, Tatiana in Eugene Onegin and Lisa in The Queen of Spades. In the meantime she had made her debut in London in 1914, and from 1924 to 1935 she performed regularly at the Royal Opera House, Covent Garden where aside from her famous Wagner roles and the Marschallin she also sang Desdemona in Otello and Donna Elvira in Don Giovanni. She appeared regularly at the Salzburg Festival from 1926 to 1937, performing with Arturo Toscanini, among other conductors. She also gave recitals there accompanied at the piano by the conductor Bruno Walter. In August 1936, while in Salzburg, she discovered the Trapp Family Singers, later made famous in the musical The Sound of Music. Lehmann had heard of a villa available for let and as she approached the villa she overheard the family singing in their garden. Insisting the children had a precious gift, she exclaimed that the family had "gold in their throats" and that they should enter the Salzburg festival contest for group singing the following night. Having regard to the family's aristocratic background the Baron insisted performing in public was out of the question, however Lehmann's fame and genuine enthusiasm persuaded the Baron to relent, leading to their first public performance.
