The photographer Peter Hujar was born in 1934 and died in 1987, at 53, 10 months after he was diagnosed with AIDS. Hujar was active in Manhattan’s 1960s art scene, and worked with Richard Avedon, Andy Warhol, Alexey Brodovitch, Susan Sontag, and Diane Arbus. He documented the gay liberation movement of the era, having witnessed the 1969 Stonewall riots. And during the 1970s and 80s, he made revealing, sometimes homoerotic, and always evocative black-and-white portraits of friends and artists. Amid an international resurgence of interest in Hujar’s photography, particularly his portraits, a new biographical film follows the artist as he navigates New York City in 1974. Peter Hujar’s Day stars Ben Whishaw, and premiered at this year’s Sundance Film Festival. —Jack Sullivan
