For many Orléanais, the name Isaac Jogues is simply that of a street. However, the North American continent, and in particular the Canadian provinces of Quebec and Ontario or the state of New York, keep the memory of the Orléan Jesuit who landed at the port of Quebec one day in the summer of 1636. He left there for a mission of evangelization among the Huron tribes, he knew martyrdom at the hands of the Mohawks and was declared a saint by the Catholic Church. The conference proposed by Gérard Hocmard aims to retrace his journey and follow him in his ascent of the St Lawrence and his death in the region of Lake George, in the Adirondacks, north of New York.
