Paul Louis Toussaint Heroult
From Graces Guide
Paul Heroult (1862-1914), Metallurgist
1886 Inventor of a process for electrolytically reducing refractory ores, especially used in the extraction of aluminium. Charles Martin Hall of Oberlin, Ohio, USA, made a similar discovery at the same time.
Unlike Hall, Heroult devoted most of his attention to the manufactme of alloys; his first French patent described a coal-fired crucible adapted for the preparation of the simple metal; the second one, which was taken up by the Societe Metallurgique Suisse at Neuhausen, claimed a process for actually fusing alumina by means of a powerful electric current, and then electrolysing it in presence of copper to yield aluminium bronze.[1]
