Aerial view of Alcoa plant, Warrick Operations at 4400 State Route 66 in Newburgh, IN. From the company's website, here's a brief history: "July 9, 1886--Working with his sister Julia in a shed attached to the family home in Oberlin, Ohio, chemistry student Charles Martin Hall discovers a way to produce aluminum through electrolysis that drastically reduces its cost. Hall patents his process and an industry is born around the light, strong metal. Around the same time, the same process is discovered by chemist Paul T. H�roult of France, and it comes to be known as the Hall-H�roult Process. Today, the Hall-H�roult Process is the one method by which every aluminum producer in the world operates." October 1, 1888:[Hall founds the Pittsburgh Reduction Co.]...1907: The Pittsburgh Reduction Company changes its name to The Aluminum Company of America." The Warrick County plant had been in operation since 1960, but shut its smelter down in 2016; update: the smelter was partially restarted in 2017.
