Louis-Armand de Lom d'Arce de Lahontan, Baron de Lahontan

Louis Armand, Baron de Lahontan (9 June 1666 – prior to 1716) was a French artistocrat, writer, and explorer who served in the French military in Canada, where he traveled extensively in the Wisconsin and Minnesota region and the upper Mississippi Valley. Upon his return to Europe he wrote an enormously popular travelogue. In it he recounted his voyage up the "Long River," now thought to be the Missouri. He wrote at length and in very positive terms about Native American culture, portraying Indian people as free, rational, and generally admirable. Provided by Wikipedia
