Name:
Named in 1827 by Wilhelm Karl von Haidinger in honor of Pierre Berthier [July 3, 1782, Nemours, Seine-et-Marne, France – August 24, 1861 France], French chemist and mineralogist at the Ecole des Mines and he was Inspector of Mines during his career. He named a number of species including chamosite, franklinite, halloysite, and nontronite. He is well-know for his study of bauxite.
