Louis Joliet (1645-1700) was a Canadian explorer (born in Québec City) who explored the Canadian wilderness, including the Great Lakes area. He and Father Jacques Marquette found the Mississippi River in 1673; they were the first Caucasians to see the Mississippi River. Together, they travelled along Lake Michigan to Green Bay, canoed up the Fox River, and went downstream on the Wisconsin River to the Mississippi River. They travelled almost to the mouth of the Arkansas, and then stopped because they were warned of hostile Indians and Spanish explorers. They returned via the Illinois River, then the Chicago River to Lake Michigan. Joliet’s journal and his maps were lost when his canoe overturned on the rapids of the Montreal River. Marquette’s diary is all that remains of their journey. Joliet expanded fur trade westward, did extensive mapping, and established a fort on Anticosti Island.
