In September 1856, Edward Orramel Austin came to Freeman Run. He fell in love with the area and began to build a village. From then on, he lived his entire life in the valley. He served in the Civil War and returned to his valley after. His dream grew until his town, at one period, was one of the largest in Potter County. At the time of his death in 1908, the town of Austin was at its most productive with paper mills and saw mills as well. He lived to see a great dream come true. Two years later, nearly the entire town was swept away when the great dam built by the Bayless Pulp and Paper Company failed to hold back its 500,000,000+ gallons of water. The home of E.O. Austin went with it.
