Fritz Haarmann
German serial killer (1879–1925)

Friedrich Heinrich Karl "Fritz" Haarmann (25 October 1879 – 15 April 1925) was a German serial rapist and serial killer, known as the Butcher of Hanover, the Vampire of Hanover and the Wolf Man, who committed the sexual assault, murder, mutilation and dismemberment of at least twenty-four young men and boys in the city of Hanover between 1918 and 1924.
Found guilty of twenty-four of the twenty-seven murders for which he was tried, Haarmann was sentenced to death by beheading in December 1924. He was subsequently executed by guillotine in April 1925.
Haarmann became known as the Butcher of Hanover (German: Der Schlächter von Hannover) due to the extensive mutilation and dismemberment committed upon his victims' bodies, and by such titles as the Vampire of Hanover (der Vampir von Hannover) and the Wolf Man (Wolfsmensch) because of his preferred murder method of biting into or through his victims' throats.
Early life
Childhood
Fritz Haarmann was born in Hanover on 25 October 1879, the sixth and youngest child born to Johanna (née Claudius) and Ollie Haarmann.
Haarmann was a quiet child, with few friends his own age or gender, and who seldom socialized with any children outside of school, with the exception of his siblings. From an early age, Haarmann's behaviour was noticeably effeminate, and he was known to shun boys' activities, instead playing with his sisters' dolls and dressing in their clothes. He also developed a passion for both needlework and cookery, and would develop a close relationship with his mother, who spoiled her youngest child.
Reportedly, Haarmann's father married his mother when she was 41 years old and seven years his senior, largely due to her wealth and the substantial dowry their marriage would eventually bring him. Haarmann Sr.

The linked authority identifier is Q61887. VIAF identifies the subject as 40172827. The Library of Congress control number is nr97039253. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1879, 1925, 1918 and 1924.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
