Margarete Klose, (August 6, 1902 in Berlin as Frida Klose – December 14, 1968, Berlin), was a German operatic mezzo-soprano.
The native of Berlin lost her father early in life and had to earn her living as a secretary, until a colleague recommended her to the Klindworth-Scharwenka conservatory, where she got a thorough musical education.
Klose made her début in 1926 at Ulm theatre in a supporting role of Emmerich Kalman's operetta Countess Maritza. Her next role was Azucena in Giuseppe Verdi's Il trovatore. For the next three years Klose sang in Ulm and Kassel, before joining the Nationaltheater Mannheim in 1929.
In 1932 Klose went back to Berlin where she was engaged alternately at Berlin State Opera (1932 to 1949 and 1955 to 1961) and Deutsche Oper Berlin (1949 to 1958).
In addition she was a celebrated guest e. g. at Vienna State Opera, the Royal Opera House Covent Garden, La Scala in Milan, Sächsische Staatsoper Dresden, Nationaltheater München, Hamburgische Staatsoper, Teatro Colón in Buenos Aires, La Monnaie in Brussels, in San Francisco and Los Angeles.
From 1936 to 1942 Klose regularly sang at the Bayreuth Festival every summer, where she became popular especially in the role of Brangäne in Tristan und Isolde. She also sang at the Richard Wagner-Festival in Sopot (1935) and the Salzburg Festival (1949 and 1955).
When in 1946 the great Wagner soprano Frida Leider gave her farewell concert in Berlin, Klose was her partner on stage.
In 1961 Margarete Klose retired from the stage and concentrated fully on her teaching activities. In the summer she regularly gave master classes at the Salzburg Mozarteum.
In 1968 she died suddenly at the age of 66.
