Richard Green (6 June 1936 – 6 April 2019) was an American-British sexologist, psychiatrist, lawyer, and author specializing in homosexuality and transsexualism, specifically gender identity disorder in children. Green was the founding editor of the Archives of Sexual Behavior (1971), and served as Editor until 2001. He was also the founding president of the International Academy of Sex Research (1975), which made the Archives its official publication. He served on the American Psychiatric Association DSM-IV Subcommittee on Gender Identity Disorders. Education and career Green was born in Crown Heights, Brooklyn, New York. His father was an accountant and his mother a teacher. He earned his BA from Syracuse University in 1957, his MD from Johns Hopkins University School of Medicine in 1961, and his J.D. from Yale Law School in 1987. During his medical studies at Johns Hopkins, Green met John Money, who was an assistant professor there, and started collaborating with him on research, initially on boys displaying substantial cross-gender behavior. In 1960, they published the paper "Incongruous Gender Role: Nongenital Manifestations in Prepubertal Boys," detailing their observations of 5 children assigned male at birth (AMAB) who "showed incongruities in gender role", ranging from preferring to play with girls to praying God would change them into a girl. Citing that adult gay men and transgender women recollect gender incongruity in childhood, they later concluded early intervention is best in cases of gender incongruity and that "part of the successful rearing of a child is orienting him, from birth, to his biologically and culturally acceptable gender role. This, as far as we know, is best achieved by providing a relationship between husband and wife exemplifying these respective roles." In 1961, they published a paper titled “Effeminacy in Prepubertal Boys,” which looked at eleven AMAB youth who were referred for their “excessive and persistent attempts to dress in the clothes of the opposite gender, constant display of gestures and mannerisms of the opposite sex, preference for play and other activities of the opposite sex, or a stated desire to be a member of the opposite sex.” They recommended that parents "Look for insidious and irrational ways in which parents may be unwittingly encouraging girlishness and penalizing their son for developing boyishly. [...] Both [parents] should convey to their son their whole-hearted approval of his present and future masculine behavior and sexuality." The paper conflated gender identity, gender expression and sexual orientation,
