Founded in 1806 by William Bruce, it celebrated its bicentennial in the summer of 2006. It derives its name from Gen. William Eaton (1764–1811), the U.S. Consul at Tunis, who led a diverse army in a harrowing march from Egypt to Tripoli to meet the U.S. Naval forces. In addition to the city of Eaton and the county of Preble, various streets in Eaton (Decatur, Israel, Wadsworth and Somers) were also named in honor of various heroes of the First Barbary War and the Second Barbary War .
The town grew quickly following its establishment. In 1846, the town first had 1000 inhabitants. This growth was primarily derived from the town's location at the strategic junction of two turnpikes. In 1849, Eaton was the site of a cholera outbreak. About half of the inhabitants fled; of the remaining 600 people, 120 died.
19th century fire 
In June 1859 a fire in Eaton destroyed thirteen of its primary business establishments. The total loss was estimated at $40,000 to $50,000. Caused by incendiaries, the fire scorched the courthouse and left it a brown color. The disaster was first reported by the Cincinnati Commercial.
