Karl von Ledebur
Director of the Schwerin Hoftheater, Germany (b. 1/13 February 1840 in Berlin; d. 4 November 1913 at Schwerin); also known as Carl von Ledebur, or Karl Freiherr von Ledebur.
Following an initiative by the Hamburg-based impresario Bernhard Pollini, Karl von Ledebur staged Tchaikovsky's opera Iolanta at the Schwerin Hoftheater on 25 December 1892/6 January 1893, three days after the opera's first performance in Germany (in Hamburg), and just nineteen days after its world première in Saint Petersburg. Although Tchaikovsky had promised to attend the performance of his opera in Schwerin , he subsequently changed his mind and did not do so.
