Transvestism
Transvestism was a medicalized framework primarily used in the late nineteenth and early twentieth centuries to classify and explain varied forms of gender-variant expression and behavior. Coined by Magnus Hirschfeld in 1910, the term included a diverse range of phenomena that later came to be understood separately as cross-dressing, aspects of homosexuality, eonism, transsexuality, and transgender identity, but was not limited to any single one of these concepts.
