John Money

John William Money (8 July 1921 – 7 July 2006) was a New Zealand psychologist, sexologist and author. He researched human sexuality and gender identity.
Money was a professor at Johns Hopkins University in the United States.
Money created the "theory of neutrality", which argued that males and females are born without psychological differences. This lead him to conduct an experiment where he raised a boy as a girl, which failed.
