History

Williamsport was platted by (and named for) William Harrison on December 11, 1828, on the south end of the eastern fractional part of the northeast quarter of section 11, township 21, range 8. Harrison was the first to occupy the town in the fall of 1828; he built a log house at the east end of Main Street near the river and operated a ferry crossing there for several years. Though located on the opposite side of the river from the Wabash and Erie Canal, Williamsport sought to draw shipping traffic by constructing a short cut-off canal. Finished around 1852, the project led to the nickname "Side-Cut City".

Williamsport became the county seat in June 1829, taking the title away from short-lived Warrenton. Its post office was the first in the county and has operated since September 28, 1829. The town was incorporated in March 1854, at which time its population was 552.

James Frank Hanly, who was the Governor of Indiana from 1905 to 1909, lived and practiced law here from 1879 to 1896; he is buried at Hillside Cemetery, on the northeast side of town.

The Williamsport-Washington Township Public Library opened in 1917 as a Carnegie library, and moved to a new facility in 2002.
