It took 81 years before Hirschfeld’s Die Transvestiten was translated into English. Neugebauer’s Hermaphroditismus beim Menschen is still untranslated. While the social construction of sex has moved on and we no longer regard the gonads as the ultimate arbiter of which sex we are, his book is presumable a work of scholarship according to standards of the early 20th century and if so would be well worth reading alongside Hirschfeld and Havelock Ellis.
I have attached the category ‘sex-change doctor’ to Neugebauer in that based on a person’s gonads he told several who had been raised female, were happily so and even married as such that they were men and must switch, and vice versa.
I use the term ‘hermaphroditism’ here as that was the term used during Neugebauer’s lifetime.
