Charles Hall
USABiography of Charles Hall
Charles Hall was an American chemical engineer born on December 6, 1863, in Thompson, Ohio. Even as a student at Oberlin College, he began researching the properties of aluminum and methods for its industrial production. He conducted experiments on the electrolysis of cryolite-alumina melt, which yielded promising results. In order to continue his research, his father set up a laboratory at home for him.
On February 23, 1886, less than a year after graduating from college, Hall successfully obtained small aluminum ingots through electrolysis. In 1888, he managed to establish a collaboration with a Pittsburgh-based ore enrichment company. This collaboration eventually led to the creation of the "Aluminum Company of America," where Hall served as vice-president until his death.
Around the same time as Hall, another young French chemist named Paul Héroult developed a similar method for aluminum production. Héroult's electrolytic furnace proved to be more efficient than Hall's. Through close collaboration, the two young men improved the technological process, which later became known as the Hall-Héroult process and formed the foundation of modern aluminum industry.
In 1911, Hall was awarded the Perkins Medal for his achievements in applied chemistry. He also served as a prominent benefactor of Oberlin College. Charles Hall passed away on December 27, 1914, in Daytona Beach, Florida. He left a lasting legacy in the field of chemical engineering and played a significant role in revolutionizing the aluminum industry.
