In 1886, when the east-west Bald Knob branch of the St. Louis, Iron Mountain and Southern Railroad intersected the Knobel line, the town was known as Wynne Junction, but “Junction†was eventually dropped. The Bald Knob line was completed in early 1888, and Wynne was incorporated for the first time that same year. Six years earlier, Wynne`s first post-office was established with Joseph A. Martin as postmaster.
