The true story of the first California cult scandalIn 1891, a suffragist and social reformer named Alzire Chevaillier launched a moral crusade to destroy Fountaingrove, a utopian spiritualist community in northern California. Chevaillier accused the colony's leader, the poet and prophet Thomas Lake Harris, of perverting the teachings of the Bible to promote a “new sexology” that was “worse than Mormonism.” She insisted that Harris used magical powers of hypnosis to take sexual and financial advantage of his followers, turning them into a “spiritual harem” that practiced “free love” and other gross immoralities. Media reports emphasized the presence of Japanese immigrant men at Fountaingrove, raising racialized specters of miscegenation and moral contamination. The international scandal, full of the sorts of salacious details prized by newspaper editors at the dawn of the era of yellow journalism, would last more than a decade, establishing Harris as the prototype for a new type of public menace-the “California cult leader.” Unholy Sensations takes a close-up look at the Fountaingrove scandal to examine religion, gender, sexuality, and race in the Gilded Age from a fresh perspective. By chronicling the life stories of the people swept up in the scandal, Unholy Sensations reveals connections and tensions between a wide variety of nineteenth-century religious and social groups, including suffragists and spiritualists, Christian Scientists and Theosophists, journalists and politicians, and Protestant ministers and urban reformers. Together, these disparate groups helped spark California's first cult scare, demonizing Harris as the first-but far from the last-dangerous California cult leader. By showing that the term “cult” has always been a marker of race, sexuality, and religion, Unholy Sensations reveals the limits of American freedom and the centrality of religion to the policing of whiteness, family, and nation.
