Hall, Charles Martin (sh)




born Dec. 6, 1863, Thompson, Ohio, U.S.
died Dec. 27, 1914, Daytona Beach, Fla.

U.S. chemist.

He attended Oberlin College, where, soon after graduating in 1885, he discovered the method of producing aluminum by electrolysis (simultaneously with Paul Heroult), an innovation that brought the metal into wide commercial use. Supported by the Mellon family, he formed the Pittsburgh Reduction Co. (later Alcoa). The need for cheap and plentiful power led the company to Niagara Falls, where in 1895 it became the first customer for Niagara's new power plant.
