## Body

### Early Life and Career
Meriwether Lewis was born on August 18, 1774, in Ivy, Virginia. Orphaned at a young age, he was raised by relatives, including his mother's cousin, William Lewis. He joined the U.S. Army in 1792, serving in the Legion of the United States and participating in the Northwest Indian War. By 1801, he became a captain and was appointed private secretary to President Thomas Jefferson, who entrusted him with leading the expedition to explore the Louisiana Purchase.

### Lewis and Clark Expedition
From 1804 to 1806, Lewis and co-leader William Clark traversed over 7,000 miles, mapping the Missouri River, crossing the Rocky Mountains, and reaching the Pacific Ocean. The expedition documented over 100 plant species, 122 animal species, and encountered numerous Indigenous nations, producing detailed journals that became foundational to American ethnography and natural history.

### Later Life and Death
After the expedition, Lewis was appointed governor of the Louisiana Territory in 1806. He struggled with the demands of governance and personal debt. On October 11, 1809, Lewis died from gunshot wounds near Grinder's Stand, Tennessee. The official ruling of suicide has been contested, with some attributing his death to murder or accidental discharge. He was buried in Nashville, Tennessee.

### Legacy
Lewis's expedition journals, published posthumously, remain a seminal work in American exploration literature. His contributions to botany, geography, and Indigenous studies are recognized through namesakes such as Lewis County in multiple U.S. states, the *Lewisia* plant genus, and the USS *Lewis and Clark*. The 1997 NASA Earth observation satellite "Lewis" was named in his honor, commemorating his legacy in scientific exploration.
