Benjamin Louis Eulalie de Bonneville

Born in or near Paris in 1796, Benjamin Louis Eulalie de Bonneville came to the United States as a child and graduated from West Point in 1815. He built a long military career, but he is best remembered for the years when he pushed deep into the western interior, combining army discipline with the ambitions of a trader and explorer.

In 1832, he took leave from the Army and led an expedition into the Rocky Mountains and beyond. His travels reached the Green River country, the Great Basin, and parts of the Oregon Country, and he is often credited with helping blaze sections of what became the Oregon Trail. The journals and reports from those journeys later became the basis for Washington Irving's The Adventures of Captain Bonneville, the book that made his name widely known.

Bonneville later returned to regular military service and served in several major conflicts, including the Mexican-American War and the Civil War. He died in 1878, leaving behind a reputation shaped both by real exploration and by the powerful storytelling that carried his adventures to readers far from the frontier.
