ABRAHAM GOTTLOB See also:WERNER (1750-1817)  , See also:father of See also:German See also:geology, was See also:born in Upper See also:Lusatia, See also:Saxony, on the 25th of See also:September 1750 . The See also:family to which he belonged had been engaged for several See also:hundred years in See also:mining pursuits . His father was inspector of See also:Count Solm's See also:iron-See also:works at Wehrau and Lorzendorf, and from See also:young See also:Werner's See also:infancy cultivated in him a See also:taste for minerals and rocks . The boy showed See also:early promise of distinction . He began to collect specimens of stones, and one cf his favourite employments was to See also:pore over the pages of a See also:dictionary of mining . At the See also:age of nine he was sent to school at See also:Bunzlau in See also:Silesia, where he remained until 1764, when he joined his father at Wehrau with the See also:idea of ultimately succeeding him in the See also:post of inspector . When nineteen years of age (1769) he journeyed to See also:Freiberg, where he attracted the See also:notice of the officials, who invited him to attend the mining school established two years previously . This was the turning point in Werner's career . He soon distinguished himself by his See also:industry and by the large amount of See also:practical knowledge of See also:mineralogy which he acquired . In 1771 he repaired to theuniversity of See also:Leipzig and went through the usual curriculum of study, paying See also:attention at first chiefly to the subject of See also:law, but continuing to devote himself with See also:great ardour to mineralogical pursuits . While still a student he wrote his first See also:work on the See also:external characters of minerals, Von den etusserlichen Kennzeichen der Fossilien (1774), which at once gave him a name among the mineralogists of the See also:day . In 1775 he was appointed inspector in the mining school and teacher of mineralogy at Freiberg .

To the development of that school and to the cultivation of mineralogy and geognosy he thence-forth, for about See also:

forty years, devoted the whole of his active and indefatigable industry . From a See also:mere provincial institution the Freiberg See also:academy under his care See also:rose to be one of the great centres of scientific See also:light in See also:Europe, to which students from all parts of the See also:world flocked to listen to his eloquent teaching . He wrote but little, and though he elaborated a See also:complete See also:system of geognosy and mineralogy he never could be induced to publish it . From the notes of his pupils, however, the See also:general purport of his teaching was well known, and it widely influenced the See also:science of his See also:time . He died at Freiberg on the 3oth of See also:June 1817 . One of the distinguishing features of Werner's teaching was the care with which he taught lithology and the See also:succession of See also:geological formation; a subject to which he applied the name geognosy . His views on a definite geological succession were inspired by the works of J . G . See also:Lehmann and G . C . Fuchsel (1722-1773) . He showed that the rocks of the See also:earth are not disposed at See also:random, but follow each other in a certain definite See also:order .

Unfortunately he had never enlarged his experience by travel, and the sequence of See also:

rock-masses which he had recognized in Saxony was believed by him to be of universal application (see his Kurze Klassifikation and Beschreibung der verschiedenen Gebirgsarten, 1787) . He taught that the rocks were the precipitates of a primeval ocean, and followed each other in successive deposits of world-wide extent . Volcanoes were regarded by him as abnormal phenomena, probably due to the See also:combustion of subterranean beds of See also:coal . See also:Basalt and similar rocks, which even then were recognized by other observers as of igneous origin, were believed by him to be See also:water-formed accumulations of the same See also:ancient ocean . Hence arose one of the great See also:historical controversies of geology . Werner's followers preached the See also:doctrine of the aqueous origin of rocks, and were known as Neptunists; their opponents, who recognized the important See also:part taken in the construction of the earth's crust by subterranean See also:heat, were styled Vulcanists . R . See also:Jameson, the most distinguished of his See also:British pupils, was for many years an ardent teacher of the Wernerian doctrines . Though much of Werner's theoretical work was erroneous, science is indebted to him for so clearly demonstrating the See also:chronological succession of rocks, for the enthusiastic zeal which he infused into his pupils, and for the impulse which he thereby gave to the study of geology .
