Karoline Jagemann

Baroness Karoline Jagemann von Heygendorff (25 January 1777, in Weimar – 10 July 1848, in Dresden) was a major German tragedienne and singer.

She made her debut in 1792 in the title role of the opera Oberon – The Fairy King by Paul Wranitzky at Mannheim's Nationaltheater and was engaged as a court-singer in Weimar in 1797.

She and the soprano Henriette Eberwein (1790 - 1849),[1] the tenor Carl Melchior Jakob Moltke, and the bass Karl Stromeier collectively made up the "Weimar Quartet".

In 1809 her lover, Grand Duke Karl August, made her "Freifrau (Baroness) von Heygendorff" and left her Heygendorf manor.

Witnessed by the Grand Duke, their son Karl was officially granted the Heygendorff title on 16 May 1809 and he and his children entered the Saxon grand-ducal nobility.
