Description

Includes correspondence and business records related to the business interests of Cornelius and Alexander Tiers, Herman Frasch, and Franklin Rockefeller in a sulfur-mining business.

Background note
Herman Frasch (1851–1914) was born and educated in Germany. He came to the United States as a young man and established a chemical laboratory in Philadelphia. In 1887 Frasch patented a method of removing foul-smelling sulfur compounds from "sour" oil. In 1894 Frasch adapted the technology of the oil industry to sulfur mining and devised a means whereby the sulfur could be pumped out of the ground rather than mined. The process made American sulfur competitive with the more easily mined sulfur of Sicily. By securing an economical and reliable source for sulfuric acid, Herman Frasch helped the infant U. S. chemical industry break free of European domination. Frasch was awarded the Perkin Medal for his innovations. He died in Paris.
