Paul Näcke

Paul Adolf Näcke (born 23 January 1851 St. Petersburg, Russian Empire – died 18 August 1913 Colditz) was a German psychiatrist and criminologist.

Näcke is known for his writings on homosexuality, and coining the term narcissism in 1899 to describe someone who treated his body as a sexual object.

Näcke is considered a strong opponent of positive criminology, that was founded by Cesare Lombroso.

By 1900, he published a work entitled The castration of certain classes of degenerates as an effective way of social protection (title translated)[8] Näcke wrote on the subject of a Jewish character, which was described only in vague and general features, and considered that character as a reason for crimes committed by Jews.

He developed the idea that homosexuality should not be regarded as a mental illness, but as an innate natural property.
