EDMOND

HEBERT (s812-189o)  , French geologist, was born at Villefargau, Yonne, on the 12th of June 1812 . He was educated at the College de Meaux, Auxerre, and at the Ecole Normale in Paris . In 1836 he became professor at Meaux, in x838 demonstrator in chemistry and physics at the Ecole Normale, and in 1841 sub-director of studies at that school and lecturer on geology . In x857 the degree of D. es Sc. was conferred upon him, and he was appointed professor of geology at the Sorbonne . There he was eminently successful as a teacher, and worked with great zeal in the field, adding much to the knowledge of the Jurassic and older strata . He devoted, how-ever, special attention to the subdivisions of the Cretaceous and Tertiary formations in France, and to their correlation with the strata in England and in southern Europe . To him we owe the first definite arrangement of the Chalk into palaeontological zones (see Table in Geol . Hag., 1869, p . 200) . During his later years he was regarded as the leading geologist in France . He was elected a member of the Institute in 1877, Commander of the Legion of Honour in 1885, and he was three times president of the Geological Society of France . He died in Paris on the 4th of April 1890 .
