Louis Caryl Graton

Louis Caryl Graton (1880–1970), American geologist, chemist and educator, began his career in 1900 as assayer for Ledyard Gold Mines Ltd., near Rockdale, Ontario.

He moved on to Canadian Goldfields Ltd. later in 1900, then entered McGill University as a graduate student, studying many of the famous mines of Ontario and Quebec.

Graton made important contributions in applying the science of geology to the practical job of finding ore.

For Cerro and other industrial clients, he set up modern geological departments and trained staff geologists to high professional standards.

He was president of the Society of Economic Geologists in 1931 (winning its Penrose Gold Medal in 1950[1]), among many other awards and honors.
