Lewis, a horse trader and former Union Army officer, helped establish the community in the late 1870s or early 1880s. After marrying a local widow, Lewis purchased a half-section of land and proceeded with plans to build a town and a town square – he hoped that the town would eventually serve as the seat of government for a new county. When a post office was established in 1882, the site was named London.
