Eleonore von Schwarzenberg ("Eleonore Elisabeth Amalia Magdalena"; 20 June 1682 in Mělník – 5 May 1741 in Palais Schwarzenberg, Vienna) was a member of the Princely House of Lobkowicz by birth, and a Princess of Schwarzenberg by marriage.
Biography.
Princess Eleonore Elisabeth Amalia Magdalena of Lobkowicz, was a daughter of Prince Ferdinand August of Lobkowicz (1655–1715), the Duke of Sagan, and his second wife, Margravine Maria Anne Wilhelmine of Baden-Baden (1655–1701), daughter of Wilhelm, Margrave of Baden-Baden.
On 6 December 1701 Princess Eleonore married the Austrian Hofmarschall, Adam Franz Karl Eusebius, Hereditary Prince (and later Prince) von Schwarzenberg. Eleonore was considered a cultivated woman, and her and her husband's wealthy and cultured lifestyle was often displayed at court. The marriage produced two children:
After 21 years of marriage her husband was killed in a hunting accident on imperial land near Brandýs nad Labem-Stará Boleslav, today in the Czech Republic. Emperor Charles VI fired the deadly shot, and the prince just happened to be in the way. Afterwards, the emperor took Eleonore's son to his court in Vienna, and she was paid a baronial maintenance of 5,000 guldens.
Princess Eleonore died on 5 May 1741 in the Palais Schwarzenberg in Vienna. Franz , the emperor's physician, requested an autopsy from which the cause of death has been diagnosed as cervical cancer.
Vampirism.
The 2007 Austrian documentary "The Vampire Princess" features Eleonore as the supposed inspiration for Gottfried August Bürger's work Lenore (ballad).
