David Reimer (August 22, 1965 as Bruce Reimer – May 4, 2004) was a Canadian man who was born as a healthy male, but was sexually reassigned and raised as female after his penis was accidentally destroyed during circumcision. Psychologist John Money oversaw the case and reported the reassignment as successful, and as evidence that gender identity is primarily learned. Milton Diamond later reported that Reimer never identified as female, and that he began living as male at age 14. Reimer later went public with his story to discourage similar medical practices. Due to years of severe depression and a dissolving marriage, he committed suicide.
