French soldier and explorer who was largely responsible for establishing French control over the country north and west of Lake Superior. The city of Duluth, Minn., was named for him.

DuLhut became an ensign in the regiment at Lyon in 1657, and about 1665 he became an officer in the royal household regiment. He fought against the Dutch under the Great Condé in 1674, by which time he had already made two voyages to New France.

In 1675 he returned to Montreal until September of 1678, when he led a party of Frenchmen and three Indian slaves to the Lake Superior country, where he hoped to negotiate peace among the Indian tribes north and west of the lake (a rich source of beaver pelts). In September 1679 DuLhut was able to bring the Indians together in a seemingly successful assembly in which amity was declared among the tribes. After wintering in the West, DuLhut decided to move farther west the next summer in search of the western ocean. The party penetrated well into what is now Minnesota and reached the Mississippi River.

On returning to Montreal, DuLhut found himself accused as a renegade trader, in violation of a 1676 edict prohibiting Frenchmen from venturing into the woods as traders. He returned to France to clear his name but was back in 1682 and the next year went off again to the West to renew his peacemaking efforts and to try to dissuade the Indians from trading their pelts to the English. He also raised Indian support for French troops and campaigned with Louis de Frontenac against the Indian allies of the British, the Oneida and Onondaga. In 1696 he was in command at Fort Frontenac. Thereafter he retired to spend his waning years in Montreal.
