Born in New York City in 1921 into a notable family, Wagstaff followed an arc that was typical of a young man of his class. He attended both Hotchkiss and Yale, served in the navy, and would follow in step with his Ivy League classmates to the "gentleman's profession," as an ad executive on Madison Avenue. With his unmistakably good looks, he projected an aura of glamour and was cited by newspapers as one of the most eligible bachelors of the late 1940s. Such accounts proved deceiving, for Wagstaff was forced to live in the closet, his homosexuality only revealed to a small circle of friends. Increasingly uncomfortable with his career and this double life, he abandoned advertising, turned to the formal study of art history, and embarked on a radical personal transformation that was in perfect harmony with the tumultuous social, cultural, and sexual upheavals of the 1960s.

Accordingly, Wagstaff became a curator, in 1961, at Hartford's Wadsworth Atheneum, where he mounted both "Black, White, and Gray"--the first museum show of minimal art--and the sculptor Tony Smith's first museum show, while lending his early support to artists Andy Warhol, Ray Johnson, and Richard Tuttle, among many others. Later, as a curator at the Detroit Institute of Arts, he brought the avant-garde to a regional museum, offending its more staid trustees in the process.

After returning to New York City in 1972, the fifty-year-old Wagstaff met the twenty-five-year-old Queens-born Robert Mapplethorpe, then living with Patti Smith. What at first appeared to be a sexual dalliance became their now historic lifelong romance, in which Mapplethorpe would foster Wagstaff's own burgeoning interest in contemporary photography and Wagstaff would help secure Mapplethorpe's reputation in the art world. In spite of their profound class differences, the artistic union between the philanthropically inclined Wagstaff and the prodigiously talented Mapplethorpe would rival that of Stieglitz and O'Keefe, or Rivera and Kahlo, in their ability to help reshape contemporary art history.

Positioning Wagstaff's personal life against the rise of photography as a major art form and the simultaneous formation of the gay rights movement, Philip Gefter's absorbing biography provides a searing portrait of New York just before and during the age of AIDS. The result is a definitive and memorable portrait of a man and an era.
