George Ferdinand Becker (1847-1919) advanced the study of mining geology from physical, chemical, and mathematic approaches. In 1874 Becker became an instructor of mining and metallurgy at the University of California at Berkeley. There he met Clarence King, the first director of the U.S. Geological Survey. Becker secured a position with King's survey and began studying the mining districts of the West Coast. This report is his best known report resulting from this study. (Encyclopedia Britannica).
