· Herman Frasch (born Dec. 25, 1851, Gaildorf, Württemberg—died May 1, 1914, Paris) was a U.S. chemist who devised the sulfur mining process named in his honour. The Frasch process, patented in 1891, was first used successfully in Louisiana and in east Texas. It made possible the exploitation of extensive sulfur deposits otherwise
