The story
The Commercial Solvents Corporation was established at the end of World War I; earning distinction as the pioneer producer of acetone and butanol by fermentation processes developed and patented by Dr. Chaim Weizmann. Terre Haute, Indiana was chosen to be the site of CSC's research as this location made possible the expedient translation of new processes from the laboratory and demonstration plant into full production.
As early as 1917, the corporation began work in Terre Haute, Indiana. It developed the conversion of corn and other grains into ethanol by fermentation. They later produced riboflavin by microbial action.
