Lost Prophet is one of the saddest stories you will ever read. Rustin was a charismatic leader, a lifelong pacifist, an imprisoned conscientious objector during World War II, and a leading American teacher of Gandhian nonviolence . . . But Rustin was also gay, decades before the Supreme Court legitimated private sexual activity, and that cost him the backing of some radicals, black as well as white, for whom he had been an eloquent and courageous leader for nearly 40 years. . . . D'Emilio succeeds in detailing a highly useful life and–a prime task of biography–in redeeming a nearly forgotten figure and assigning him a proper role in an era that becomes more beclouded and mythologized with every passing year.
