French Candian Catholic explorer and geographer. Born Quebec, Canada, 1645; died in Canada, 1700. He received minor orders in 1662, but became interested in exploration. In 1672Governor Fiontenac dispatched him to explore the Mississippi. Together with Marquette, he started out at Fox River, crossed Wisconsin, and sailed down the river as far as 30° 40' north latitude, and established the fact that it emptied into the Gulf of Mexico. Shipwrecked at Lachine on his homeward journey, he lost the journal of his voyage, but this was supplied by his verbal report and the journal of Marquette.
