Denounced by the New York Times as an "unmitigated rascal" while simultaneously being lauded as a reincarnation of Gautama Buddha himself, Henry Steel Olcott (1832–1907) was friend to Madame Blavatsky, co-founder of the Theosophical Society, and an indefatigable reformer and culture broker between East and West. Olcott helped bring about a new spiritual creation, Protestant Buddhism, a creative creolization of American Protestantism, traditional Theravada Buddhism, and other influences. Stephen Prothero's portrait of Olcott is an engaging study of spiritual quest and cross-cultural encounters.
