Pierre Chouteau, Jr. was an American merchant and trader who grew up to run a powerful trading company that monopolized the trade along the upper Missouri River.

Pierre Chouteau, Jr. was born into the wealthy Chouteau fur-trading family of St. Louis, Missouri, to Jean Pierre Chouteau and Pelagie Kiersereau on January 19, 1789. As a boy, he was familiarly called “Cadet,” a French Creole word that means second-born son. He received elementary education in St. Louis, but before he was 16, he worked as a clerk in his father’s store and traded with the Osage tribe.

He was tall, erect, with coal-black hair, penetrating black eyes, and a pleasant expression.

In 1810, he left St. Louis to look after his family’s interests in lead mines in Dubuque, Iowa, where he remained until the War of 1812 erupted. He then returned to St. Louis, where he opened a store with his brother-in-law, Bartholomew Berthold, and became involved in the fur trade. On June 15, 1813, he married his first cousin, Emilie Gratiot, and the pair would eventually have five children.

Berthold and Chouteau soon began outfitting traders destined for points in the west. In 1815, they backed Pierre’s brother Auguste Chouteau, Jules DeMun, and John Sarpy on an expedition to the upper Arkansas River region. The men were arrested in 1817 by the Spanish, as they considered that area under their control. Auguste and the others were imprisoned in Santa Fe, New Mexico, and their trade goods were confiscated. Though his brother was later released, the event temporarily disillusioned Pierre with the fur trade business.

However, Berthold and Chouteau sometimes called the French Company, continued, and in 1819, they backed a trading expedition by Manuel Lisa to the Upper Missouri River but again suffered heavy losses.

Though they had other successes, Berthold and Chouteau struggled in the increasingly competitive St. Louis fur market. They reorganized in 1822 and added another partner — Bernard Pratte, who was married to Pierre’s cousin. The company then became known as Berthold, Chouteau & Pratte.

All three men then began to make several expeditions to the upper Mississippi and Missouri Rivers and built several trading posts on the Missouri River as far north as present-day South Dakota. In about 1827, Chouteau began to prosper when he arranged to purchase furs and supply goods to the Rocky Mountain Fur Company. Pierre Chouteau, Jr. was a driven man, a ruthless competitor, and an innovator who introduced steamboat navigation on the Missouri River in 1832, revolutionizing the scale of the fur trade.

As Chouteau and his partners prospered, they competed with various fur trading companies, especially the American Fur Company. However, Pierre Chouteau, Bartholomew Berthold, John P. Cabanne, and Bernard Pratte gradually eased into a relationship with John Jacob Astor, who owned the American Fur Company. In 1827, Bernard Pratte & Company joined the American Fur Company’s Western Department as its St. Louis agent.

Pierre was a passenger with Artist George C. Catlin when the Yellow Stone completed the first successful steamboat voyage to the upper Missouri River country in 1832.

In 1834, when John Jacob Astor, the owner of the American Fur Company, retired, Bernard Pratte and Pierre Chouteau Jr. purchased the Missouri River interests of the American Fur Company’s Western Department, forming the Pratte, Chouteau, and Company. The northern portion of the American Fur Company’s interests was sold to Ramsay Crooks, who retained the “American Fur Company” name.

Pratte, Chouteau, and Company quickly became a dominant force in the fur trade on the Central and Northern Great Plains, with a network of trading posts stretching from Fort Union, North Dakota, to Fort Laramie. Wyoming.

In 1838, Bernard Pratte retired, and Pierre Chouteau, Jr. gained control of the firm and reorganized it as the Pierre Chouteau, Jr. and Company, which would become the dominating trading company on the Missouri River. The near-monopoly enjoyed by the company from the mid-1830s was gained primarily by the combined use of light-draft steamboats and an illegal distillery at Fort Union, North Dakota. The new company soon discontinued the fur business and focused on buffalo robes, moving hundreds of thousands through St. Louis to the main markets in the eastern United States over the next 25 years.

In 1842, Ramsay Crooks sold his interest in the Red River and upper Mississippi watersheds to Pierre Chouteau, Jr., & Company. In 1845, the financial backers of the Union Fur Company sold their trading posts to their competitor, Pierre Chouteau, Jr.

In 1847 Pierre and his brother Auguste established Fort Benton, Montana, as the last fur trading post on the Upper Missouri River. It was named for U.S. Senator Thomas Hart Benton, with whom the Chouteau family were friends and influential contributors.

During these busy years, the Pierre Chouteau, Jr., & Company employed or partnered with several well-known frontiersmen, including Alexander Culbertson, Andrew Dawson, Malcolm Clarke, Kenneth McKenzie, Alexander Harvey, and Louis Rivit.

Pierre’s son Charles took charge of managing the St. Louis fur business from him in 1849, and Pierre focused on several other business interests. He engaged in banking and Iron Mountain deposits in St. Francois County, Missouri, and in 1850 he was a partner in the firm of Chouteau, Harrison & Valle that operated a rolling mill in North St. Louis. He was one of the original incorporators of the Ohio & Mississippi Railroad of Illinois. As his business interests grew, he was drawn to New York City, where he was one of the country’s leading financiers for many years.

In the late 1850s, Pierre’s health began to fail, and in 1859 he lost his sight. That same year, the first successful attempt to extend steamboat traffic to the head of navigation of the Missouri River at Fort Benton, Montana, was undertaken by Pierre Chouteau, Jr., & Company on the steamboat Chippewa. The federal government sponsored the voyage to carry the Indian annuity of goods to the upper Missouri agencies. It was transporting a corps of engineers under the command of Captain W.F. Raynolds. Before this voyage, Fort Union, North Dakota, situated at the mouth of the Yellowstone River, had long been the head of navigation.

Three years later, his wife of 50 years, Emilie, died on August 24, 1862. Pierre Chouteau Jr. died in St. Louis, Missouri, two years later, on September 6, 1865. They are buried in a mausoleum at the Calvary Cemetery in St. Louis.

The Pierre Chouteau, Jr., & Company continued until 1864 and was sold in 1865. His children inherited an estate of several million.

“As a merchant and a man of business for nearly half a century, Chouteau had no equal in the Mississippi Valley.”
