Bernard Zuger, a pediatrician and psychiatrist who studied effeminacy in boys and was among the first professionals to suggest a possible link with adult male homosexuality, died on April 19 at Metropolitan Hospital Center in New York. He was 92 and lived in New York City.

He died as a result of a stroke that he suffered on April 17, his family said.Zuger began studying effeminate behavior in boys in the 1950s after several parents came to him with concerns about their sons' behavior. He began to track the development of those who became his patients, noting that the vast majority became gay men.

Zuger, a native Russian, immigrated to the United States as a child with his family and they settled on the Lower East Side of Manhattan. After becoming a doctor and serving as an Army officer in Egypt during World War II, Zuger studied psychiatry.
