Margarete Henriette Therese Roßkopf-Bäumer (26 May 1898 – December 1969) was a German operatic soprano.
[2] At the Staatsoper Stuttgart, Bäumer switched to the dramatic repertoire in the mid-1920s and from then on was increasingly celebrated as a Wagner singer.
On the occasion of an engagement at the German Grand Opera Society in New York, she performed on tour on all major North American stages.
Innumerable guest performances at the opera houses of Europe followed in addition to her regular engagements.
Thus she sang - mainly in Wagnerian roles - in Vienna (Staatsoper), Brussels, Dresden (Staatsoper), Basel, Geneva, Paris, Barcelona, Zurich, Prague, Riga, Copenhagen, Amsterdam, Venice, Palermo and Turin.
