The town was founded in 1869 on a 50-acre (20 ha) grant from two local landowners, judge Robert Eastwood and pastor Roland Gooch, in order to function as a stop on the Evansville, Henderson, and Nashville Railroad. The city was laid out by (and named for) a railway's engineer and surveyor named Henry B. Hanson.[3] The community received its post office on December 7, 1869,[4] and was incorporated by the state assembly on March 31, 1873.[5]
The Evansville, Henderson, & Nashville was purchased by the St. Louis and Southeastern in 1872, which (following a reorganization) was purchased in turn by the L&N in 1879.
The city was essentially destroyed by a fire in 1889,[3] and the present historic district dates from the rebuilding that followed.[6] Today, the former L&N network makes up part of CSX Transportation, which operates a siding track in Hanson.
According to the United States Census Bureau, Hanson has a total area of 2.6 square miles (6.8 km2), of which 0.01 square miles (0.03 km2), or 0.50%, are water.[2]
