(b Vienna, 19 Aug 1882; d Vienna, 20 July 1957). Austrian baritone. He studied in Milan, then made his début in 1904 at the Neues Deutsches Theater, Prague, as Telramund. After engagements at Linz, the Vienna Volksoper and the Vienna Hofoper, in 1916 he joined the Munich Hofoper, where he remained until 1922; he then returned to the Vienna Staatsoper until 1938 and was made an Austrian Kammersänger. In Munich he sang Meister Florian in the 1920 revised version of Franz Schreker's Das Spielwerk und die Prinzessin and Barak in the first performance there of Die Frau ohne Schatten. He appeared regularly at Covent Garden (1924–8) as the Dutchman, Kurwenal, Hans Sachs, Wotan, Telramund, John the Baptist and Amonasro, in Chicago (1928–9) and at the Teatro Colón. Schipper sang Agamemnon in Iphigénie en Aulide at the 1930 Salzburg Festival and returned there in 1935–6 as Kurwenal. He also made guest appearances in France, the Netherlands, Spain and Belgium. His voice was powerful and dramatic, but he did not always use it with subtlety. He married the mezzo-contralto Maria Olszewska, with whom he recorded a notable version of the Wanderer-Erda encounter from the third act of Siegfried.
