THEVENAU, Charles Etienne (tay-vay-no), West Indian naturalist, born in St. Lucia in 1758; died in Paris in 1820. He took part as an ensign in the war of 1778-'83 in the West Indies, and after the conclusion of peace held an office in the magistracy of St. Lucia. At the beginning of the French revolution he went to Paris, where he became noted as a journalist; but he strongly opposed the enfranchisement of the slaves, and for his attacks against the club called "Les amis des noirs" was imprisoned during the reign of terror. Being released after the reaction of 1794, he returned to St. Lucia and devoted himself to agriculture and science. After the restoration of Louis XVIII. he settled in Paris. His works include "Observatiolls sur des poissons recueillis dans un voyage a la Baie de Samana, et description des especes nouvelles et pen connues" (St, . Lucia, 1788); "Monographie des Ignames" (Paris, 1790): "Historia naturalis plantarum quas in insula Santa Lucia crescent" (3 vols., 1802-'9); " Enumeratio plantarum cellularium quas in insula Santa Lucia a Thevenau collectas describit" (3 vols., 1807-'12) ; " Fasciculus plantarum rariarum et exotiearum" (1813); "Essai sur les simples veneneux des Antilles" (1814) , and "Traite des arbres fruitiers des Antilles" (2 vols., 1816).
