It's longer than that. As far as I am aware, sexologist John Money was the first to use the term in a sociological sense, in his 1955 paper Hermaphroditism, gender and precocity in hyperadrenocorticism, where he wrote: "The term gender role is used to signify all those things that a person says or does to disclose himself or herself as having the status of boy or man, girl or woman, respectively. It includes, but is not restricted to, sexuality in the sense of eroticism." Some decades on, he noted that the rationale for introducing the term was to "make it possible to write about people who came into one's office as either male or female, but of whom it could not be said that their sex role in the specific genital sense was either male or female insofar as they had a history of birth defect of the sex organs. The majority of people who contributed to this new meaning of gender were hermaphrodites or intersexes. To them, social science and social history overall owe a debt of gratitude."
