Born in Union City, New Jersey, Hammond earned a B.A. in English from Columbia College. In addition to his work as a theater journalist, he was a writer and editor for Moorehouse/Barlow, New York University Press, the Museum of Modern Art (NY), the New York Native, Opera Monthly, and the literary magazine Christopher Street. A gay activist, he co-founded the International Gay History Archive in 1981; the collection is now housed in the Rare Books and Manuscripts division of the New York Public Library. In 2001, Hammond relocated to Toronto, Canada and was involved with the historic house museums there, launching and editing a newsletter for volunteers.
