History The first known settlers of the Parkersburg area were John Connell and his son William, who built a log cabin in 1857. A railroad company surveyed the area in the early 1860s. A depot was erected in 1865 and two railroads, the Illinois Central and the Chicago North Western, were built through the town. The town was soon platted and recorded and given the name of "Parkersburg" in honor of Pascal P. Parker, a prominent settler and the town's first postmaster. The first major business was a hotel built by Thomas Williams, called The Williams House. Later, it became known as the Commercial House. Parkersburg was incorporated on December 7, 1874. The first "School House" was built in the 1860s. Parkersburg became an independent school district in the spring of 1871. A new school was built in 1872. This building burned beyond repair on October 9, 1893, in the "great fire of Parkersburg", which also destroyed most of the business district. In 1894 a modern, three-story, brick structure was built. In 1930, the school added an auditorium and gymnasium. The first electric power was furnished by the Parkersburg Electric Light & Power Company, composed of local citizens who built the plant in 1898 at a cost of $10,000. Parkersburg's roads were paved circa 1920. The first water tower only had a capacity of 40,000 gallons. 2008 tornado Seven people died in Parkersburg and two in rural New Hartford from injuries sustained when a confirmed EF5 tornado struck the region on May 25, 2008.
