He left Pittsburgh and earned his Ph D from Harvard University in 1952.

Finally, Money created the now-common term gender role which he differentiated from the concept of the more traditional terminology sex role.

For him, gender included not only one's status as a man or a woman, but was also a matter of personal recognition, social assignment, or legal determination; not only on the basis of one's genitalia but also on the basis of somatic and behavioral criteria that go beyond genital differences.
