DeSoto, Indiana, was originally platted as the village of Woodlawn on January 15, 1881, by landowner Luther L. Perdieu. The settlement developed around the new Lake Erie & Western Railroad depot in southeastern Delaware Township. Perdieu laid out sixteen lots along the tracks, and the village quickly grew, with sawmills and businesses emerging to support the local economy. However, when Perdieu applied for a post office, the name "Woodlawn" was rejected due to its similarity to another Indiana post office. He then resubmitted the application under the name "DeSoto," likely in homage to the Spanish explorer Hernando de Soto.
