Wentzville, Missouri, was founded in 1855 by William M. Allen, a tobacco farmer and state senator. Allen knew that the new railroad would run through Missouri, so he used his senatorial influence to convince railroad engineers, particularly chief engineer Erasmus Livingston Wentz, to lay the tracks through his farmland and build a station with a promise to name the town after Wentz. The tobacco industry became a driving force for Wentzville's early growth. Since 1983, when General Motors built its plant on the outskirts of town, the population has exploded. Yet the Wentzville historic area maintains a small-town feeling that charms anyone who takes the time to explore.
