Count von Racowitza
Boyar Janko Prince von Racowitza (died 1865) was a nobleman from Wallachia, who participated in a notable duel on 28. August 1864. He had come from Romania to Berlin in 1856, where he studied philosophy and law at Berlin university. He became a member of a German Student Corps there.
A diplomat in Bavarian service, Wilhelm von Dönniges (d. 1872), father of Helene von Dönniges (b. 1846, d. 1911) intended the prince to marry his daughter. She preferred a Social Democratic leader of the labour movement, Ferdinand Lassalle, known for his independence from persons such as Karl Marx. When her father heard of their plans to marry he locked her in a room and arranged an engagement with von Racowitza. Lasalle challenged Helene's father. When the count heard of this, he took over Lasalle's challenge - this was a common duelling procedure, when an older man was challenged by a younger one. Racowitza had no experience in the use of pistols and only one day to exercise. Shot in the groin, Lassalle died in this pistol duel in Switzerland. Following the duel Racowitza fell ill and died not long after Helene von Dönniges married him. His widow married a second time an actor named Friedmann and became an actress herself. This marriage ended in divorce in 1873. Together with her third husband, the Russian nobleman Sergej Jegorowitsch Schewitsch she then moved to America but returned to Europe 1890.
