Karl Heinrich Ulrichs and the early sexologists

Hello Douglas,
This is a great subject - Ulrichs was influenced by a number of different scientific disciplines and that influence is apparent in his writings in all kinds of ways. You might be interested in my article "Transforming Sexuality: The Medical Sources of Karl Heinrich Ulrichs (1825-1895) and the Origins of the Theory of Bisexuality," Journal of the History of Medicine and Allied Sciences, 67 (2012), 177-216.
All the best,

Dear Douglas,

I'm not sure he actually communicated with scientists of his day - I believe he was rather monomaniacal - but he did read their work and used it to his own advantage (much to the displeasure of other then gay activists). He was familiar, for example, with an extensive discussion in entomology about same-sex copulation in cockchafers. I just finished a chapter on this discussion, which includes a few pages on Ulrichs. I can send you a copy if you're interested.

Best wishes,

Pieter R. Adriaens

Thanks all! Ross, I have printed off your article!

Pieter, Ulrichs wrote to quite a number of leading forensic psychiatrists of his day and ended up having a correspondence with Krafft-Ebing over several decades (though we only know of that because Krafft-Ebing refers to it in a letter and is quoted by Ulrichs). He was a bit of a monomaniac though may have tried to involve others. By "other then gay activists" I presume you mean Kertbeny? Or did you mean people other THAN gay activists? I'd be interested though in your chapter.
