"Sieur de La Salle" identifies RenΓ©-Robert Cavelier as a French nobleman and explorer. 'Sieur' is a French title equivalent to 'Lord' or 'Sir.' He explored the Great Lakes region and the Mississippi River. Think of him as the early version of a CEO, strategically expanding his company (France) into new markets. He claimed the Mississippi River basin for France, naming it Louisiana. Unlike current business travelers, he used canoes and dealt with wilderness.
