Born in Breslau, Heidersbach first wanted to become a pianist and studied piano at the conservatory of her home town.
She then took singing lessons with Juan Luria (who was later interned by the Nazi regime and murdered at the Sobibor extermination camp in 1943), Lola Beeth and Fred Husler.
[1] Guest performances led the artist to Dresden, Amsterdam, Vienna, Zurich, Hamburg, Munich and Barcelona.
[5] On 2 June 1939, she sang Eve in a gala performance of Die Meistersinger von Nürnberg in honour of the Regent Prince Paul of Yugoslavia, which was also attended by Adolf Hitler.
[6] This performance became legendary because Karajan, who conducted without a score, got out of time and thus incurred the wrath of the Führer.
