John Money, New Zealand-American psychologist and author (b. 1921)
John William Money (8 July 1921 – 7 July 2006) was a controversial New Zealand psychologist, sexologist and author known for his research into sexual identity and biology of gender and his conduct towards vulnerable patients, including endorsing conversion therapy aimed at young children. He was one of the first researchers to publish theories on the influence of societal constructs of gender on individual formation of gender identity. Money introduced the terms gender identity, gender role and sexual orientation and popularised the term paraphilia. He spent a considerable amount of his career in the United States.

Recent academic studies have criticized Money's work in many respects, particularly in regard to his involvement with the involuntary sex-reassignment of the child David Reimer, his forcing this child and his brother to simulate sex acts which Money photographed and the adult suicides of both brothers.Money's writing has been translated into many languages and includes around 2,000 articles, books, chapters and reviews. He received around 65 honors, awards and degrees in his lifetime.

He was also a patron of many famous New Zealand artists, such as Rita Angus and Theo Schoon.
