Hirschfeld’s use of the weaponized concept of love was itself a legacy of Hirschfeld’s “scientific mentor” and co-ethnic Iwan Bloch (1872–1922). Like Moll and Hirschfeld, Bloch had no background in zoology, evolutionary studies or animal behavior. Trained as a dermatologist, Bloch was also attracted to the cause of “sexual minorities” and became an ardent campaigner on their behalf. He joined with Moll and Hirschfeld in attacking the non-Jewish consensus that sexual inversion was pathological and coined the term sexualwissenschaft or sexology to give academic and medical respectability to what was essentially a Jewish intellectual reaction against non-Jewish efforts to categorize harmful social and sexual pathologies. He was also a keen promoter of perversion and pornography. He was the “discoverer” of the Marquis de Sade’s manuscript of The 120 Days of Sodom , which had been believed to be lost, and published it under the pseudonym Eugène Dühren in 1904. In 1899 he had published Marquis de Sade: His Life and Works under the same pseudonym. In 1906 he wrote The Sexual Life of Our Time in its Relations to Modern Civilization , for which he gained the praise of Sigmund Freud for attacking “bourgeois” (non-Jewish) sexual mores, attacking the perception of sexual inverts as pathological, and calling for Europeans to adopt a more pluralistic and hedonistic sexual life.
