Meriwether Lewis
Meriwether Lewis (1774–1809) was a key figure in early American exploration. As co-leader of the Lewis & Clark Expedition, and later Governor of the Louisiana Territory, his discoveries, administrative struggles, and mysterious death continue to fascinate historians.
Introduction
Meriwether Lewis (August 18, 1774 – October 11, 1809) was an American explorer, soldier, public administrator, and a central figure in the early period of U.S. westward expansion. He is best known for leading the Corps of Discovery with William Clark on the Lewis & Clark Expedition (1804–1806), a monumental journey to explore the lands acquired in the the Louisiana Purchase.
Beyond exploration, Lewis served as Governor of the Upper Louisiana Territory and acted for a time as Thomas Jefferson’s private secretary. Though his life ended prematurely and under controversial circumstances, his contributions to American geography, natural science, and the nation’s understanding of its western lands have left a lasting legacy.
Early Life and Family
Meriwether Lewis was born on August 18, 1774, at the Locust Hill Plantation in Albemarle County, Virginia (now near Ivy, Virginia).
When Meriwether was about five years old, his father died (of pneumonia) in November 1779.
During his youth in the frontier region of Georgia, Lewis developed skills in hunting, survival, and natural observation. His mother also taught him about gathering medicinal herbs from the wild, planting the seeds of his later scientific interests.
Because of the frontier setting and his family’s movements, Lewis did not have extensive formal schooling in early childhood. Around age 13, he returned to Virginia under private tutors and continued his education there.
He had a sister Jane and a brother Reuben.
Early Career: Military & Political Connections
In 1794, during the Whiskey Rebellion, Lewis joined a Virginia militia unit to help suppress the uprising.
He rose through the ranks, eventually becoming a captain. During this time, he came into contact with various senior figures, including William Clark (who would later co-lead the exploration mission) and Thomas Jefferson.
In 1801, Jefferson (already President) appointed Lewis as Private Secretary to the President—a role that provided him proximity to the executive office, influence, and access to resources.
While serving in that capacity, Jefferson began planning a major exploratory expedition westward into the newly acquired Louisiana Territory. He selected Lewis to lead the expedition.
Lewis & Clark Expedition (1804–1806)
Objectives & Commissioning
Following the Louisiana Purchase in 1803, there was much unknown about the vast swath of land the United States had acquired from France. Jefferson envisioned an expedition that would map the new territory, establish trade and diplomatic relations with Native American tribes, and seek a navigable water route (or routes) across the continent to the Pacific.
Jefferson’s criteria for the expedition’s leader were exacting. He wanted someone with scientific training in botany, natural history, astronomy, mineralogy, combined with good character, ability to adapt, and familiarity with the wilderness. He saw in Lewis the blend of scientific curiosity and personal qualities suited for the journey.
Lewis then recruited William Clark to be a co-commander of what would be called the Corps of Discovery.
The Journey & Discoveries
The expedition left in 1804 and traversed thousands of miles from the Missouri River across the continental interior to the Pacific Northwest and back.
They crossed the Rocky Mountains, reached the Columbia River, and arrived at the Pacific in late 1805.
On their return in 1806, they brought back invaluable scientific, geographic, and cultural data, and proved the feasibility of overland travel to the Pacific.
The mission is widely considered one of the most successful and significant exploratory undertakings in American history.
Risks and Incidents
Lewis faced numerous hazards on the journey: treacherous terrain, harsh weather, tension with tribes, disease, starvation, and dangerous wildlife. One vivid anecdote: at one point, Lewis found himself sliding down a cliff and barely saved himself with his long knife.
On one occasion near the Great Falls of the Missouri, Lewis nearly forgot to reload his rifle before a grizzly attack—only narrowly avoiding disaster.
Another incident: in August 1806, Lewis was shot in the thigh by a fellow expedition member, Pierre Cruzatte (though it’s disputed whether intentional or accidental). He endured significant pain but recovered enough to continue.
Post-Expedition Years & Governorship
Administrative Challenges
After the expedition, Lewis received a land grant of 1,600 acres and sought to publish the expedition journals.
In 1807, Jefferson appointed him Governor of the Upper Louisiana Territory (sometimes called the Louisiana Territory).
During his governance, Lewis attempted to implement infrastructure (roads, laws), mediate disputes among Native tribes, regulate trading licenses and land grants, and promote the fur trade.
However, his tenure was beset by difficulties. Communication with Washington was slow. He clashed with his territorial secretary Frederick Bates, who accused Lewis of mismanagement and seeking illegitimate gains. As debts piled up and critics questioned his decisions, Lewis grew increasingly stressed.
The expense claims that Lewis had made for the territory were delayed or denied by the War Department. This financial strain was a major pressure on his final years.
Final Journey & Death
In September 1809, Lewis embarked on a troubled return journey to Washington, D.C., to settle financial disputes and advance publication of the expedition accounts.
He traveled overland along the Natchez Trace, a route notorious for robberies and violence. He stopped at Grinder’s Stand, an inn about 70 miles southwest of Nashville, Tennessee.
In the early hours of October 11, 1809, gunshots rang out in his cabin. Lewis was discovered mortally wounded, with multiple gunshot wounds—one to the head and one to the abdomen (or gut). He died shortly after sunrise.
Whether his death was by suicide or murder remains unresolved. Thomas Jefferson and some contemporaries accepted suicide as the cause, citing Lewis’s emotional strain, debts, and possible substance abuse.
However, others—including his family and later historians—proposed the possibility of homicide by highway robbers (common along the Trace), or other foul play.
An 1811 letter from Lewis suggested he had attempted suicide earlier on the journey, though was restrained.
Because no eyewitnesses testified, and contemporary reports are inconsistent, scholars continue to debate the nature of his death.
Lewis was interred near the site of his death (in present-day Hohenwald, Tennessee). His grave was later marked with a monument and fenced.
