In September 1850, Philadelphians George L. Lewis and Samuel Fox Fisher, along with Charles Lennig, a German Quaker and successful chemical manufacturer, chartered and located on this site the Pennsylvania Salt Manufacturing Company. The place was chosen because of the abundance of salt and coal, the two main ingredients of soda ash, which the company hoped to produce and sell to the steamboat traffic on the Mississippi River. The Pennsylvania Main Line Canal (1829-1865), ran right past the Penn Salt site and provided a transportation linkage East and West.

In 1852 Penn Salt began producing soda alkali and selling it to Cincinnati soap-makers. Soon thereafter, they marketed "Natrona Refined Saponifier," individually packaged containers of caustic soda, or lye, for home soap making. The new product sold well and made the company its first profit. It also prompted a change in the town's name in 1862, from East Tarentum to Natrona, from the Greek Natron, meaning soda.

Penn Salt workers also manufactured bleaching detergents, refrigerants, and numerous pesticides, including DDT and chemical defoliants used in the South Pacific during World War II. Penn Salt was vital to the U.S. war effort: in 1943, a cарtured list of American sites targeted for demolition by the Nazis found Natrona number three.

The uniqueness of the Penn Salt National Historic District derives in part from its Philadelphia and Quaker origins. Natrona was a different sort of company town-paternalistic yet more benevolent than most coal-patch and steel towns of western Pennsylvania: the company paid the rent of families whose Fathers served in the Civil War, served the town with water, light and power and provided land for the early churches.
