Hall, Charles Martin

Hall, Charles Martin

(1863–1914) engineer, manufacturer; born in Thompson, Ohio. In 1886, shortly after graduating from Oberlin College, Hall developed a new means of producing aluminum. In 1888 he organized the Pittsburgh Reduction Company to manufacture aluminum. Because he greatly reduced its cost, Hall is credited with making the metal a staple of the U.S. economy.
