WERNER, See also:ABRAHAM GOTTLOB (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 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.
