Chouteau was the name of a highly-successful ethnically-French furtrading family based in Saint Louis, Missouri, which they helped found.
The family sold the Chouteau posts along the upper Missouri River in 1865 after the American Civil War to Americans James B. Hubbell, Alpheus F. Hawley, James A. Smith, C. Francis Bates.
Hubbell, based in Minnesota, already had some licenses from the federal government to trade with Native Americans in the West.
They formed the Northwestern Fur Company and operated it through posts along the upper Missouri River until 1870.
They closed the business due to losses of equipment and furs during the Sioux uprising and warfare during the 1860s, which resulted in a volatile environment that made it too difficult to operate.
