Daughter of the Viennese cabaret artist Oskar Teller, Friedl Teller-Blum escaped with her parents to America after the 1938 Anschluss as a six year-old refugee.
She made her first stage appearance at 16, was recruited to the Metropolitan Opera Studio and sang more than 40 roles, including Violetta and Butterfly.
In 1961 she migrated to Israel, where she performed with all the leading ensembles and headed the voice department at Tel Aviv University. Friedl died yesterday in Givatayim.
