1975: Transgenderist

1975 usage of Transgenderist, Phyllis Frye

This is perhaps the most tantalizing clue to where “transgenderist” may have originated.  According to this 1975 letter, Frye first discovered the term in Sussie Collins’,  magazine, Female Impersonator News. Sussie Collins was the national Director of the United Transvestite and Transexual Society – one of the early TS/TV national organizations, formed in 1973.
