Peter Kurten was a German serial killer known as both The Vampire of Dusseldorf and the Dusseldorf Monster, who committed a series of murders and sexual assaults between February and November 1929 in the city of Dusseldorf. In the years prior to these assaults and murders, Kurten had amassed a lengthy criminal record for offenses including arson and attempted murder. He also confessed to the 1913 murders of a 9-year-old girl in Mulheim am Rhein, and a 17-year-old girl in Loscheckes.
Described by Karl Berg (de) as "the king of the sexual perverts," Kurten was found guilty of nine counts of murder and seven counts of attempted murder for which he was sentenced to death by beheading in April 1931. He was subsequently executed in July 1931. Kurten became known as The Vampire of Dusseldorf as he occasionally made attempts to drink the blood from his victims' wounds, and the Dusseldorf Monster both because the majority of his murders were committed in and around the city of Dusseldorf, and the savagery he inflicted upon his victims' bodies.
