(16407-1701), a missionary of the Order of Recollets of St. Francis, was born in Belgium. He came to Canada in 1673, and founded a convent at Fort Frontenac in 1676. He accompanied La Salle's expedition to the West and to the Niagara and the Upper Lakes in 1678, and constructed Fort Crevecoeur in Illinois. Hennepin and his followers proceeded down the Mississippi until captured by the Sioux in 1680. On his return to Europe he published his "Description de la Louisiane nouvellement decouverte an sud-ouest de la Nouvelle France," and in 1697 his "Nouvelle decouverte d'un tres-grand pays situe dans I'Ame'rique, entre le Nouveau-Mexique et la merGlaciale." He claimed to be the first to descend to the mouth of the Mississippi, but this is open to dispute.
