Yves-Joseph de Kerguelen-Trémarec

Yves Joseph Marie de Kerguelen-Trémarec (13 February 1734 – 3 March 1797) was a French Navy officer. He discovered the Kerguelen Islands in 1772 during his first expedition to the southern Indian Ocean. Welcomed as a hero after his voyage and first discovery, Kerguelen fell out of favour after his second voyage (1773-1774) and was cashiered in 1775 for violating Navy regulations. He was rehabilitated during the French Revolution.

Kerguelen authored books about expeditions and about French naval operations during the American Revolutionary War. Provided by Wikipedia
