Olszewska left Leipzig to join the Hamburg State Opera, where she was engaged from 1919 to 1922. While there, she notably portrayed Brigitta/Lucienne in the world co-premiere[3] of Erich Wolfgang Korngold's Die tote Stadt on 4 December 1920. While singing in Hamburg, she was appointed to the roster of artists at the Vienna State Opera (VSO) in 1921 where she sang through 1923. She was a member of the Bavarian State Opera in Munich from 1923 to 1925, after which she returned to the VSO from 1925 to 1930. In 1925, she married the baritone Emil Schipper [Wikidata] (1882–1957).[2]
Olszewska appeared frequently as a guest artist at opera houses around the world. In 1923 and 1928 she was heard as a guest at the Teatro Colón in Buenos Aires. She made numerous appearance at the Royal Opera, London between 1924 and 1932, where her performances in such roles as Fricka, Ortrud, Brangäne and Herodias drew the highest critical acclaim. Her Carmen and Amneris were less successful, but her Octavian and Orlofsky were highly regarded. In the United States, she sang in Chicago (1928–1932) and at the Metropolitan Opera. She also gave performances at La Scala, La Monnaie, and highly successful tours in South and Central America.[2]
