Antonio de Ulloa

Antonio de Ulloa y de la Torre-Giral (12 January 1716 – 3 July 1795) was a Spanish general of the navy, explorer, scientist, author, astronomer, colonial administrator and the first Spanish governor of Louisiana. He was appointed to that office after France ceded the territory to Spain in 1763, following its defeat by Great Britain in the Seven Years' War. Ulloa's rule was resisted by the French Creole colonists in New Orleans, who expelled him in 1768 from West Louisiana.

Ulloa had already established an international reputation in science, having been part of the French Geodesic Mission in present-day Ecuador. He and a fellow Spaniard discovered the element platinum and Ulloa wrote the first scientific description of it. He published an extensive record of his observations and findings on the South American trip, which was published in French in 1848 and in English as ''A Voyage to South America'' (1806). He was a Fellow of the Royal Society and a foreign member of the Royal Swedish Academy of Sciences
