His expeditions were vital for mapping the Oregon Country and the Great Basin. These journeys helped create paths like the Oregon Trail. Bonneville became a household name through a book written about him. This book turned his real-life adventures into a famous story for many readers.

Bonneville's life began in or near Paris, France, in 1796. His parents were Nicholas Bonneville, a publisher, and Marguerite Brazier. When Benjamin was seven, his family moved to the United States. A man named Thomas Paine paid for their passage. Paine was the godfather to Benjamin and his brothers, Louis and Thomas. After Paine died in 1809, he left an estate to Marguerite. This included a 100-acre farm in New Rochelle, New York. This inheritance allowed her to educate her sons.

In 1813, Bonneville entered the United States Military Academy at West Point. He graduated in only two years as a brevet second lieutenant of light artillery. He served at various posts in New England, Mississippi, and the Arkansas Territory. By 1824, he was promoted to captain at Fort Gibson. During a trip to France, he met General Lafayette. Later, in 1828, he moved to Jefferson Barracks in Missouri. In Missouri, he felt inspired to explore the American West. He read writings by Hall J. Kelley and editorials in the St. Louis Enquirer.

Bonneville sought permission from General Alexander Macomb to explore the West. He argued that he could perform reconnaissance in the Oregon Country. At that time, the region was under joint occupation by the U.S. and Britain. The Hudson's Bay Company largely controlled the area. Macomb granted a 26-month leave from August 1831 to October 1833. Bonneville was instructed to gather useful information for the government. He was to pose as a fur trader to study the natural history. He needed to document the climate, soil, geography, and mineral production. He also had to study the local tribes. Private donors, including Alfred Seton and possibly John Jacob Astor, paid his expenses.

His most famous expedition began in May 1832 with 110 men.

He was joined by lieutenants Michael Cerre and Joseph R. Walker. The trip was financed by John Jacob Astor. The group traveled from Fort Osage up the Missouri River. They crossed present-day Wyoming and reached the Green River in August. There, they built a trading post called Fort Bonneville. Some mountain men called it "Fort Nonsense" because it was never used for trading. In 1833, Bonneville explored the Snake River in present-day Idaho. He met a young Shoshone guide named John Enos. During this time, he sent Joseph Walker to find a route to California. Walker discovered a path through the Sierra Nevada mountains. This became the California Trail, used later by gold seekers.

Exploring the West presented many difficult challenges. The Hudson's Bay Company, led by John McLoughlin, made business difficult. McLoughlin forbade his traders from working with Bonneville. This meant Bonneville struggled to trade or find supplies. He faced many rejections at Fort Nez Perces and Fort Vancouver. These difficulties caused him to stay longer than his 26-month leave allowed. When he finally returned to Missouri in 1835, he found his military commission had been revoked. He spent much time petitioning the Secretary of War, Lewis Cass, to get his job back. He was successful in 1836.

Bonneville continued a long and distinguished military career. He served in the Mexican-American War and was part of the occupation of Mexico City. He later became a colonel of the 3rd Infantry Regiment in 1855. During the Civil War, he served in Missouri and St. Louis. He was eventually honored as a brevet brigadier general.

After retiring for a second time in 1866, he moved to Fort Smith, Arkansas. He married Sue Neis there. Bonneville died in 1878 at the age of 82. He is buried at Bellefontaine Cemetery in St. Louis.

His adventures reached a wider audience through literature. While in New York, Bonneville met the famous writer Washington Irving. Irving was interested in the stories of the West. They agreed on a deal where Bonneville provided maps and notes for $1,000. Irving used these to write "The Adventures of Captain Bonneville," published in 1837. This book made Bonneville a celebrity. Today, his name is found on many things. These include Bonneville County in Idaho and even a crater on Mars. His legacy lives on through the trails he helped map and the stories he shared.
