Lisbeth Sättler was born in Schwarzenberg. Her father was a teacher, and supplied her first musical education. She made her operatic debut in Dresden opposite Richard Tauber on 16 June 1915, as Arsena in the operetta Der Zigeunerbaron by Johann Strauss. In 1916 she performed leading roles such as the Countess Mozart's Figaro, Eva in Wagner's Die Meistersinger von Nürnberg. In 1919, Richard Strauss entrusted her to perform the role of the Empress in his Die Frau ohne Schatten, she was so successful that he wanted to engage her at the Vienna State Opera. She was then recognised internationally, and appeared at major operas houses in Europe. She moved to the US and remained with the Metropolitan Opera for 20 seasons, singing 30 roles. Her four Met opening nights (Wagner's Die Walküre, Mozarts Figaro and two times Aida) tie her with Licia Albanese as the soprano awarded the most Met opening nights. She also was engaged by London's Royal Opera House, where she sang in 1925 and from 1934–1939.
The most notable records of her art include live Metropolitan Opera recordings of her role in the complete operas, including Marriage of Figaro, Verdi's Simon Boccanegra and Otello, and Wagner's Lohengrin. Concerning her lieder discography, she was included in the 1930s Hugo Wolf Society recording project (e.g. "Müh'voll komm' ich und beladen").
