Jean François Sylvestre Denis de Trobriand

Jean François Sylvestre Denis de Trobriand was born in Finistère in France on 7 June 1765 and died on 16 March 1799 on Saint-Domingue. He was a French naval officer and navigator who particularly distinguished himself during the expedition of d'Entrecasteaux to Australasia (1791–94). The Trobriand Islands in Papua New Guinea were named after him.

Trobriand came from an aristocratic family from Brittany. He was one of three children of Jean François Sylvestre Denis, count of Trobriand (1729-1810) and Jeanne Charlotte Le Gris du Clos (1735- ). He joined the French Navy and became a midshipman in 1780, initially serving under Bouganville and taking part in the US War of Independence. In 1791 he embarked as a first lieutenant on the Espérance, a ship captained by Kermadec, which was one of the two vessels of an expedition mounted by d'Entrecasteaux, to search for an earlier expedition led by Lapérouse. The d'Entrecasteaux expedition explored parts of the Australian coast, Tasmania, New Caledonia, the Solomon Islands, Vanuatu, and, in what is now Papua New Guinea, the Admiralty Islands, before heading to Ambon in the Moluccas to take on supplies. It then returned towards Australia. The death of Kermadec in New Caledonia led to a decision to return to France. En route the ships passed through the Louisiade Archipelago whose islands include some subsequently named after Trobriand.
