August Chouteau and his half-brother Pierre dominated the St. Louis-based fur trade when the Lewis and Clark Expedition arrived in 1803. Auguste is sometimes referred to as René Auguste, the same name as his father, the co-founder of St. Louis. In their seminal work on the Chouteaus, Foley and Rice explained the family’s position in American history:
Described variously as the “Royal Family of the Wilderness,” the “First Citizens of Upper Louisiana,” and the “Founding Family of St. Louis,” this distinguished clan of merchant-capitalists assumed an active and vital role in opening the trans-Mississippi West.[1]William E. Foley and C. David Rice, The First Chouteaus: River Barons of Early St. Louis (Urbana: University of Illinois Press, 1983), ix.
On 28 December 1809, Toussaint Charbonneau and Sacagawea were in a St. Louis vertical log church to baptize their son Jean Baptiste Charbonneau. Auguste Chouteau and his daughter Eulalie signed the baptismal record, and Auguste is listed by the priest as the child’s godfather. Clark would likely have been there, but he was in Washington City at the time.[2]See on this site The Charbonneaus in St. Louis.
Auguste continued working closely with Clark. In 1815, Indian Commissioners William Clark, Ninian Edwards, and Auguste Chouteau completed treaties with a dozen nations meeting at Portage des Sioux just north of St. Louis. By 1820, Auguste and Clark would conclude fifteen more for a total of twenty-seven treaties.[3]Stan Hoig, The Chouteaus: First Family of the Fur Trade (Albuquerque: University of New Mexico Press, 2008), 261–63.
