Strauss advised her to move to Berlin, and in 1936 she joined the Berlin State Opera, where she was a prima donna until 1946. That year, she sang "Susanna" in "Le Nozze di Figaro", Zerlina in "Don Giovanni", and Sophie in "Der Rosenkavalier" for Dresden Semper Opera Company's performances at Covent Garden Royal Opera House of London. From then on, she appeared at many great opera houses including Vienna State Opera and La Scala Opera House of Milan.
