people—and for Commercial Solvents, the patents have served their purpose. Without them, the corporation would hardly have been able to develop its markets so rapidly and broadly, nor could it have carried on research so extensively in industrial bacteriology and chemistry.In the years following Weizmann’s contribution, operations of Commercial Solvents have been so diversified that products manufactured by the Weizmann process provided only a relatively small part of the company’s revenue.After 1922, the Weizmann patent was carried on the books at a valuation of only one dollar. Commercial Solvents businesses included specialty and commodity chemicals for industry, agricultural chemicals, animal health and nutrition products, industrial explosives and carbon blacks.Its products for human health and animal health and nutrition were developed largely through the company’s expertise in fermentation technology that began in the early days of the corporation’s history.It continued to reflect, both in its allegiance to Terre Haute and its emphasis on fermentation chemistry, its origins in the discoveries of Chaim Weizmann.
