#[0] Dr. John Money's research on gender identity and expression was conducted primarily at the Johns Hopkins University School of Medicine in Baltimore, Maryland, where he served as the head of the Gender Identity Clinic. The clinic was established in the 1950s and was one of the first centers in the United States to provide medical and psychological treatment to transgender individuals. As a university-affiliated clinic, it is likely that the clinic was funded through a combination of government grants and private donations. However, I don't have access to the specific funding sources that supported Dr. Money's research, so I can't say for sure which companies or organizations were involved.
