American chemist, inventor and engineer. In 1886 he invented an inexpensive method for producing aluminium by means of electrolysis. Coincidentally, French inventor Paul Louis-Toussaint Héroult designed a very similar process the same year, having both of them worked separately and without knowledge of each other's investigations or existence. This method has become the industry's standard for the obtention of pure aluminium at low cost, and is called the Hall-Héroult process. He continued his research and development for the rest of his life and was granted 22 US patents, most on aluminium production. He served on the Oberlin College Board of Trustees and was vice-president of the Alcoa corporation until his death.
