Invented a sugar-evaporation process.
1800 Born in New Orleans, USA, the son of Vincent Rillieux and Constance Vivant. He studied engineering in Paris.
1830 Devised a vacuum evaporation process, but was unable to interest any French firms, so he returned to New Orleans and obtained a patent in 1843. His equipment became generally accepted for processing sugar cane juice, greatly reducing the price of refined sugar. He became wealthy, but left the USA in the face of racial hostility and discrmination, and returned to France, where he embarked on the study of Egyptology.
In 1881, Rillieux adapted his multiple effect evaporation system to extract sugar from sugar beet.
1894 Rillieux died on October 8, at the age of 88.
