(b Berlin, 6 Aug 1902; d Berlin, 14 Dec 1968). German mezzo-soprano. After study in Berlin with Marschalk and Bültemann she made her début at Ulm in 1927. From 1928 to 1931 she was a member of the Mannheim Opera, first coming to the notice of a wider public during the Paris Wagner season of 1929 when the first Ring in German was given at the Champs-Elysées by the Bayreuth ensemble. From 1931 she was a member of the Berlin Staatsoper. In 1935 she sang Ortrud under Thomas Beecham at Covent Garden and in 1936 she began to appear at Bayreuth. She was heard in London again in 1937 as Fricka, Waltraute and Brangäne, and in 1939 she appeared in Rome for the first time. In December 1945 she sang C. W. Gluck's Orfeo ed Euridice with the re-formed Berlin Staatsoper in its opening opera at the Admiralspalast. She went on to sing in North and South America, at the Salzburg Festival and in Italy, Spain, London, Vienna and Coburg. In 1949 she moved from the Berlin Staatsoper to the Städtische Oper, returning to her old company in 1958 and retiring in 1961. Klose's clear, rich voice and dignified stage bearing fitted her admirably for the Wagnerian mezzo roles in which she was best known (as can be heard in many recordings); she was a distinguished Clytemnestra in Elektra and Iphigénie en Aulide, and she also appeared with success as Gluck's Orpheus, Carmen, the Kostelnička (Jenůfa), Delilah and Albert's mother (Albert Herring), and in many of the Verdi mezzo roles.
