The Coxey Building ruins remain as a testament to an age of industry and innovation in Mount Vernon. When Jacob Coxey opened the building as a steel plant around 1900, he founded it on a network of railroads, pipelines, and commerce in Ohio. Natural resources abounded. Knox County’s industrial boom began when the Ohio Fuel Supply Company drilled a natural gas well that produced 7,000,000 cubic feet of gas every day. The company piped the gas through the Columbia Gas Transmission Company, making Mount Vernon a significant supplier to cities like Wilmington, Virginia, and Charleston, West Virginia.
