Diane Arbus was one of the most brilliant and revered photographers in the history of American art. Her portraits, in stark black and white, seemed to reveal the psychological truths of their subjects. But after she committed suicide at the age of forty-eight in 1971, the presumed chaos and darkness of her own inner life became, for many viewers, inextricable from her work.In the spirit of Janet Malcolm’s classic examination of Sylvia Plath, The Silent Woman, William Todd Schultz’s An Emergency in Slow Motion reveals the creative and personal struggles of Diane Arbus. Schultz veers from traditional biography to interpret Arbus’s life through the prism of four central mysteries: her outcast affinity, her sexuality, the secrets she kept and shared, and her suicide. An Emergency in Slow Motion combines new revelations and breathtaking insights into a must-read psychobiography about a monumental artist—the first new look at Arbus in twenty-five years.
