Pierre Berthier

Born 3 Jul 1782; died 24 Aug 1861 at age 79.French mineralogist and mining engineer who discovered bauxite (aluminium ore) on 23 Mar 1821 near the village Les Baux de Provence in southern France. On 24 May 1806, he joined the central laboratory at the Board of Mines. From 1816, he was chief of the laboratory at the École des Mines, and professor of assaying. Berthier analyzed kaolin along with dozens of other minerals and ores. He sought out phosphate deposits valuable for agriculture. He published a treatise (1943) of practical analytical procedures that were widely used by other mineralogists. In another field, Berthier noticed - before Mitscherlich - that isomorphism occurred whereby chemically different substances can have the same crystalline form and even co-crystallise.«
