Peligot, professor of applied chemistry in the Conservatoire des Arts et Métiers, was the first to isolate Uranium in 1841. The paper offered is his long account of the process and the history of the chemistry of Uranium. The process of isolation was first recorded in 1841 in ""Comptes Rendus Hebdomadaires des Séances de L'Academie des Sciences"".He ""showed that what was regarded as metallic uranium was the dioxide UO2, and first prepared the metal. He treated Uranium oxychloride mixed withcarbon in a stream of chlorine, when carbon dioxide and monoxide were evolved and uranium tetrachloride was formed. This ws reduced to the metal by heating it with potassium.""(Partington IV, p. 362).
