Jolliet

Jolliet, or Joliet, Louis (1645–1700), 17th-century French-Canadian explorer. He traversed and mapped out much of the upper Great Lakes and the Mississippi River. Accompanied by Father Jacques Marquette, he explored the Mississippi by canoe in 1673, beginning from what is now Wisconsin and traveling over 1,000 miles to the mouth of the Arkansas River. In later years, Jolliet explored the Hudson Bay region and the Labrador coast.
