Cauldwell and transsexualism

Although the German term “Transsexualismus” was introduced by Hirschfeld in 1923, Cauldwell appears to be the first to use the term in direct reference to those who desired a change of physiological sex.

Cauldwell distinguished “biological sex” from “psychological sex”, and saw the latter as determined by social conditioning. He denied that there were modes of thinking intrinsically linked to male or female biology. Primarily because of this view of gender as plastic, and secondarily because of the limitations of medical science, he regarded sex reassignment surgery as an unacceptable response to transsexualism, and instead advocated that it be treated as a mental disorder (though he advocated acceptance of homosexualism and of transvestism).
