Étienne de Boré

Jean Étienne de Boré (27 December 1741 – 1 February 1820) was a French planter who was known for producing the first granulated sugar in Spanish Louisiana, and essentially making sugar cane profitable as a commodity crop. He was prominent there at the time of the Louisiana Purchase; in 1803 the American governor of the territory appointed him the first mayor of New Orleans under the U.S. administration.
