"I have always held that Rillieux’s 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
Norbert
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.
The American Chemical Society designated the invention of the Multiple
Effect Evaporator under Vacuum a National Historic Chemical Landmark in
New Orleans, Louisiana, on April 18, 2002.
