Anna Tomowa-Sintow (born September 22, 1941, in Stara Zagora, Bulgaria) is a Bulgarian soprano who has sung to great acclaim in all the major opera houses around the world in a repertoire that includes Mozart, Rossini, Verdi, Puccini, Wagner, and Strauss. She enjoyed a particularly close professional relationship with conductor Herbert von Karajan from 1973 until the conductor's death in 1989.
Upon graduation, she joined the Opera Studio of the Leipzig Opera, where, in 1967, she made her professional debut as Abigaille in Verdi's Nabucco. While with this company she built up her repertoire with the leading roles in Puccini's Madama Butterfly and Manon Lescaut; Verdi's La traviata, Il trovatore, and Otello; Mozart's Don Giovanni; Strauss's Arabella; and Werner Egk's Die Zaubergeige. For many of these roles she studied with the company's music director, Professor Peter Schmitz, who had studied with Richard Strauss.
She is also a Kammersängerin of the Vienna Staatsoper.
In 1973, Tomowa-Sintow auditioned for conductor Herbert von Karajan for the upcoming world premiere of Carl Orff's De temporum fine comœdia at the Salzburg Festival. He hired her immediately, and for the next seventeen years (until Karajan's death) the two worked frequently together in opera houses, concert halls, and recording studios around the world. Karajan called Tomowa-Sintow "the greatest talent I have encountered over the past years."
Tomowa-Sintow made her San Francisco Opera debut in 1974, as Donna Anna in Don Giovanni; her Covent Garden debut in 1975, as Fiordiligi in Così fan tutte; her Metropolitan Opera debut in 1976 and her Lyric Opera of Chicago debut in 1980, both as Donna Anna; and her La Scala debut in 1982, as Elsa in Lohengrin.
Her recording of Ariadne auf Naxos with James Levine and the Vienna Philharmonic won the 1988 Grammy Award for Best Opera Recording.
