Abraham Gottlob Werner (1749-1817) On September 25, 1749, German geologist Abraham Gottlob Werner was born. He is best known for his early theory about the stratification of the Earth’s crust. Moreover, he propounded an earth history that others labeled Neptunism that states that holding that all rocks have aqueous origins. While most tenets of Neptunism were eventually set aside, science is indebted to Werner for clearly demonstrating the chronological succession of rocks,…
