Daubree, Gabriel Augusts

DAUBREE, GABRIEL AUGUSTS (1814-1896), French geologist, was born at Metz, on the 2Sth of June 1814, and educated at the Ecole Polytechnique in Paris. At the age of twenty he had qualified as a mining engineer, and in 1838 he was appointed to take charge of the mines in the Bas-Rhin (Alsace) , and subsequently to be professor of mineralogy and geology at the Faculty of Sciences, Strassburg. In 1859 he became engineer in chief of mines, and in 1861 he was appointed professor of geology at the museum of natural history in Paris and was also elected member of the Academy of Sciences. In the following year he became professor of mineralogy at the ficole des Mines, and in 1872 director of that school. In 1880 the Geological Society of London awarded to him the Wollaston medal. His published researches date from 1841, when the origin of certain tin minerals attracted his attention; he subsequently discussed the formation of bog-iron ore, and worked out in detail the geology of the Bas-Rhin (1852). From 1857 to 1861, while engaged in engineering works connected with the springs of Plombieres, he made a series of interesting observations on thermal waters and their influence on the Roman masonry through which they made their exit. He was, however, especially distinguished for his long-continued and often dangerous experiments on the artificial production of minerals and rocks. He likewise discussed the permeability of rocks by water, and the effects of such infiltration in producing volcanic phenomena; he dealt with the subject of metamorphism, with the deformations of the earth's crust, with earthquakes, and with the composition and classification of meteorites. He died in Paris on the 29th of May 1896.

His publications were: Etudes et experiences synthetiques sur le mttamorphisme et sur la formation des roches cristallines (1860); Etudes synthetiques de gtologie exptrimentale (1879); Les Eaux souterraines a I'tpoque actuelle (2 vols., 1887); La Eaux souterraines aux epoques anciennes (1887).
