Charles Martin Hall discovers the smelting process.
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. Héroult of France, and it comes to be known as the Hall-Héroult Process. Today, the Hall-Héroult Process is the one method by which every aluminum producer in the world operates.
The Pittsburgh Reduction Company
In Pittsburgh, Pennsylvania, Alcoa founder Charles Martin Hall finds experienced, hard-working visionary backers (led by Captain Alfred E. Hunt) for his aluminum reduction (electrolysis) discovery. The company is first incorporated as The Pittsburgh Reduction Company and opens a pilot production facility on Smallman Street. Hall hires his first employee, Arthur Vining Davis. Today, that same company is known as Alcoa.
New Kensington: cradle of aluminum innovation
As demand for the new metal grows, Alcoa moves its operations from Pittsburgh to nearby New Kensington, PA, where it scales up to produce aluminum ingots as well as fabricated aluminum products. For many years, no other company in the world can catch up with the breadth and depth of Alcoa’s aluminum production.
