Bevan, The Psychobiology of Transsexualism and Transgenderism (2014, ISBN1440831270), page 42: "The term transsexual was introduced by Cauldwell (1949) and popularized by Harry Benjamin (1966) [...]. The term transgender was coined by John Oliven (1965) and popularized by various transgender people who pioneered the concept and practice of transgenderism. It is sometimes said that Virginia Prince (1976) popularized the term, but history shows that many transgender people adovcated the use of this term much more than Prince. The adjective transgendered should not be used [...]. Transsexuals constitute a subset of transgender people."
