Harry Stack Sullivan, a gay physician at Sheppard and Enoch Pratt Hospital in Maryland, explores patients’ sexualities in relationship to divergent modes of gender, class, and race. This is the first documented therapeutic approach to sexuality. Sullivan plays the middle ground, where he does not name homosexuality as a disease to be cured nor an identity to be embraced. Instead, he focuses on working with people's experience of being homosexual, exploring how they feel about this part of their identity.
