revolution in sugar processing
"I have always held that Rillieuxs invention is the greatest in the history of American chemical engineering and I know of no other invention that has brought so great a saving to all branches of chemical engineering."
Charles A. Browne (1870-1947), Sugar Chemist, U.S. Department of Agriculture
Rillieux is little known today, but his invention, the Multiple Effect
Evaporator under Vacuum, revolutionized sugar processing. Rillieux, a
free African American, patented his invention in the 1840s. The basic
design is still in use in sugar processing and other industries.
