Herman Frasch- The Sulphur King
Herman Frasch, inventer of the hot water process for pumping out melted sulphur underground, freed American from dependence on foreign suppliers that imported the mineral. He was the recipient of more than sixty patents for inventions in areas as diverse as oil refining and hydraulic fracturing, salt and soda manufacturing, and oil based wax paper. Among the greatest American inventors of the late19th and early 20th century, he is little known today, but his life as a young immigrant from Germany who made himself "The Sulphur King" is a great American success story.
