The Pittsburgh Reduction Company was established in 1888 by Charles Martin Hall and a group of businessmen to commercialize the electrolytic process for producing aluminum.12

As demand for the metal grew rapidly, the company expanded its operations to include bauxite mining, alumina production, and hydroelectric power facilities. By 1907, the organization had grown significantly, leading it to reincorporate under the name Aluminum Company of America. This new name was eventually shortened to the acronym Alcoa, which was subsequently adopted as the company’s official name.12
