Psychiatry (Sciences), 1965
The imaginary ability to change one form of human into another merely with social engineering. Advanced and intellectual™ because it seems impossible.
In 1965, psychiatrist John Oliven published “Sexual Hygiene and Pathology” in the American Journal of the Medical Sciences, which included a definition of “transsexualism”. Four years later in 1969, the founder of cross-dressing magazine Transvestia, activist Virginia Prince, had begun to popularize the term with articles such as “The Expression of Femininity in the Male”. By 1984, the term was being regularly used in Female Mimics International.
