Inventor
Norbert Rillieux's inventions were of great value to the sugar-refining industry.
The method formerly used called for gangs of slaves to ladle boiling sugarcane
juice from one kettle to another- a primitive process known as "The Jamaica
Train."
In 1845, Rillieux invented a vacuum evaporating pan (a series of condensing
coils in vacuum chambers) which reduced the industry's dependence on gang labor
and helped manufacture a superior product at a greatly reduced cost. The first
Rillieux evaporator was installed at Myrtle Grove Plantation, Louisiana, In
1845.
In the following years, factories in Louisiana, Cuba, and Mexico converted to the Rillieux system.
A native of New Orleans, Rillieux was the son of Vincent Rillieux, a wealthy engineer, and Constance Vivant, a slave on his plantation. Young Rillieux's higher education was obtained in Paris, where his extraordinary aptitude for engineering led to his appointment at the age of 24 as an instructor of applied mechanics at L'Ecole Centrale. Rillieux returned to Paris permanently in 1854, securing a scholarship and working on the deciphering of hieroglyphics.
When his evaporator process was finally adopted in Europe, he returned to inventing with renewed interest-applying his process to the sugar beet. In so doing, he cut production and refining costs in half.
Rillieux died in Paris on October 8, 1894, leaving behind a system which is in universal use throughout the sugar industry, as well as in the manufacture of soap, gelatin, glue, and many other products.
