"Abraham Gottlob Werner (25 September 1749 – 30 June 1817) was a German geologist who set out an early theory about the stratification of the Earth´s crust and propounded a history of the Earth that came to be known as Neptunism. While most tenets of Neptunism were eventually set aside, Werner is remembered for his demonstration of chronological succession in rocks; for the zeal with which he infused his pupils; and for the impulse he thereby gave to the study of geology. He has been called the "father of German geology"." - (en.wikipedia.org 10.11.2019)
