- Jean-Baptiste-Armand-Louis-Leonce Elie de BeaumontJean-Baptiste-Armand-Louis-Léonce Elie de Beaumont† Catholic_Encyclopedia ► Jean-Baptiste-Armand-Louis-Léonce Elie de BeaumontGeologist, b. at Canon (Dép. Calvados), near Caen, France, 25 Sept., 1798; d. at Canon, 21 Sept., 1874. He made his preliminary studies at the Séminaire Henri IV in Paris, and after successfully competing the course at the Ecole Polytechnique devoted himself in 1819 to mineralogy at the Ecole des Mines. His professor of geology, Brochant de Villiers, in 1822, chose him and his fellow-student Dufrénoy as companions on a tour to England, to study the mines of the country and to become acquainted with the British methods of geological surveying. After their return, Elie de Beaumont published a series of papers in conjunction with Dufrénoy in the "Annales des Mines" (1824-1830) which were afterwards republished under the title "Voyage métallurgique en Angleterre"; 2 vols. (Paris, 1837-39). In 1825 the two young geologists began the preparation of a geological map of France. This great work, carried on, first under the direction of de Villiers and afterwards independently, required eighteen years for its completion. Its publication was an event of much importance in the development of geology in France and established the reputation of its authors. Later and more complete editions were afterwards issued and Elie de Beaumont continued to direct the work of the special geological survey until his death.In 1827 he was elected professor of geology at the Ecole des Mines and in 1832 was appointed to the same chair in the Collège de France. In 1833 he became chief engineer of mines and some years later succeeded de Villiers as general inspector of mines. He received many honours during his long career in recognition of his scientific achievements. He was admitted to the Académie des Sciences in 1835 and succeeded Arago in 1853 as its perpetual secretary. He served as President of the Geological Society of France and in 1861 became Vice-President of the Conseil Général des Mines. He was made a Senator of France in 1852 and during the Second Empire a Grand Officer of the Legion of Honour.His fame extended throughout Europe. His extensive field observations, in connexion with his surveys and his epoch-making work on the age and origin of mountain systems, constitute his chief contributions to geology. A paper published by him, as early as 1829, in the "Annales" of the Academy, may be regarded as the starting-point of modern views on mountain structure. His observations and theories on the subject are developed in detail in his "Notice sur les systèmes des montagnes": 3 vols. (1852). Elie de Beaumont was a man of ardent faith and great integrity of life. In all his official positions he was conspicuous for his fairness and consideration for his colleagues. He was also the author of "Observations sur les différentes formations dans le système des Vosges", Paris, 1829; "Mémoires pour servir à une description géologique de la France" (with Dufrénoy), 4 vols., Paris, 1830-38; "Recherches sur quelques-unes des révolutions de la surface du globe", Paris, 1834; "Explications de la carte géologique de la France", Part I, 1841; Part II-IV, 1848-78 (with Dufrénoy).DEVILLE, Coup-d'oeil historique sur la géologie et sur les travaux d'Elie de Beaumont (Paris, 1878); BERTRAND, Eloges Académiques (Paris, 1890), 77-103; VON ZITTEL, History of Geology and Palæontology (London, 1901).H.
