Sunday, November 25th, 2007b. September 25, 1750 and d. June ? 1817
German geologist and mineralogist. In 1774 he published “Treatise on the Characters of Minerals” proposing a methodical and precise language. This essay made a revolution in mineralogy. He applied the term geognosy to the science of the respective positions of minerals in the crust of the globe, and of the epochs of their origin. He presented this in his “Classification and Description of Mountains” (1787). He classified rocks as primitive, transitory, stratified and alluvial. He divined the order of superposition which is general all over the earth. He was the author of the Neptunian or Wernerian theory that the primitive and other rocks were formed by precipitation from water or some liquid.
For Chaos heard his voice; him all his train
Followed in bright procession, to behold
Creation, and the wonders of his might.
Then staid the fervid wheels, and in his hand
He took the golden compasses, prepared
In God’s eternal store, to circumscribe
This universe, and all created things.
