The Mansfield Riots of 1900. The summer of 1900 was a dangerous time in Mansfield, Ohio, when faith healer John Dowie lost his touch, his patients lost their lives, the crowds lost their calm, the police lost control, Mayor Brown lost his patience and a would-be prophet in Chicago lost his mind.  Historian and author Robert A. Carter leads you through the angry months of 1900 with a light touch and knowing humor.
