Ann Odelia Diss Debar was an adventuress who operated under many aliases during American's Gilded Age. At one time or another, she was pursued by police on at least three continents. Often incarcerated, but never reformed, she made her name a newspaper synonym for fraud carried out under the pretense of Spiritualist and occult powers. Her scandalous and bizarre career of con artistry intersected with those of Victoria Woodhull, the Vanderbilt family, Leland Stanford, Helena Blavatsky, and a host of other rich and powerful people. Her brazen exploits provided newspapers around the world with sensational copy for almost four decades, from 1870 to 1910, and earned for her the title of "the world's worst woman."
