Career
Born in Notre Dame du Gaure, Nantes, France, he served as commandant of Fort Michilimackinac, in what is now Michigan, from 1683 to 1690. In 1684 he traveled to Fort Saint Louis to assist Henri de Tonty against the Iroquois, and it is thought that during this journey he constructed a temporary fort that Tonty visited in the winter of 1685/1686, and later referred to as the Fort of Chicagou.
