Beaumont, Elie de (1798-1874): was a pupil in the Ecole Polytechnique
and afterwards in the Ecole des Mines. In 1820 he accompanied M.
Brochant de Villiers to England in order to study the principles of
geological mapping, and to report on the English mines and metallurgical
establishments. For several years M. de Beaumont was actively engaged
in the preparation of the geological map of France, which was begun in
1825, and in 1835 he succeeded M. B. de Villiers in the Chair of Geology
at the Ecole des Mines. In 1853 he was elected Perpetual Secretary of
the French Academy, and in 1861 he became Vice-President of the Conseil
General des Mines and a Grand Officer of the Legion of Honour. Elie de
Beaumont is best known among geologists as the author of the "Systemes
des Montagnes" and other publications, in which he put forward his
theories on the origin of mountain ranges and on kindred subjects.
