Louis Nicolas was a French missionary in Canada in the late 17th and early 18th century. Born August 15, 1634 in Aubenas, Vivarais (France), this Jesuit priest arrived in New France in 1664 and stayed for eleven years. He was fascinated by the wildlife and Native peoples of the New World, and is believed to have been the author of the hand-drawn book known as the Codex canadiensis, which documents these subjects. Louis Nicolas is the confirmed author of the books Histoire Naturelle des Indes Occidentales and the Grammaire algonquine. Historians believe that he died in 1682.
