Meriwether Lewis (August 18, 1774 – October 11, 1809) was an American explorer, soldier, politician, and public administrator, best known for his role as the leader of the Lewis and Clark Expedition, also known as the Corps of Discovery, with William Clark. Their mission was to explore the territory of the Louisiana Purchase, establish trade with, and sovereignty over the natives near the Missouri River, and claim the Pacific Northwest and Oregon Country for the United States before European nations. They also collected scientific data, and information on indigenous nations. President Thomas Jefferson appointed him Governor of Upper Louisiana in 1806. He died of gunshot wounds in what was either a murder or suicide, in 1809.
Life and work
Meriwether Lewis was born August 18, 1774, on Locust Hill Plantation in Albemarle County, Colony of Virginia, in the present-day community of Ivy. He was the son of William Lewis, of Welsh ancestry, and Lucy Meriwether, of English ancestry. After his father died of pneumonia in November 1779, he moved with his mother and stepfather Captain John Marks to Georgia. They settled along the Broad River in the Goosepond Community within the Broad River Valley in Wilkes County (now Oglethorpe County). He was also the great-great-grandson of David Crawford, a prominent Virginia Burgess and militia colonel.
Lewis had no formal education until he was 13 years of age, but during his time in Georgia he enhanced his skills as a hunter and an outdoorsman. He would often venture out in the middle of the night in the dead of winter with only his dog to go hunting. Even at an early age, he was interested in natural history, which would develop into a lifelong passion. His mother taught him how to gather wild herbs for medicinal purposes.
In the Broad River Valley, Lewis first dealt with Native Americans. This was the traditional territory of the Cherokee, who resented encroachment by the colonists. Lewis seems to have been a champion for them among his own people. While in Georgia, he met Eric Parker, who encouraged him to travel. At age 13, Lewis was sent back to Virginia for education by private tutors. His father's older brother Nicholas Lewis became his guardian. One of his tutors was Parson Matthew Maury, an uncle of Matthew Fontaine Maury.
He joined the Virginia militia, and in 1794 he was sent as part of a detachment that was involved in putting down the Whiskey Rebellion. In 1795, Lewis joined the United States Army, commissioned as an ensign—an army rank that was later abolished and was equivalent to a modern-day second lieutenant. By 1800 he rose to captain, and ended his service there in 1801. Among his commanding officers was William Clark, who would later become his companion in the Corps of Discovery.
On April 1, 1801, Lewis was appointed as Secretary to the President by President Thomas Jefferson, whom he knew through Virginia society in Albemarle County. Lewis resided in the presidential mansion, and frequently conversed with various prominent figures in politics, the arts and other circles. He compiled information on the personnel and politics of the United States Army, which had seen an influx of Federalist officers as a result of "midnight appointments" made by outgoing president John Adams in 1801. Meriwether was elected a member of the American Philosophical Society in 1802.
When Jefferson began to plan for an expedition across the continent, he chose Lewis to lead the expedition. Meriwether Lewis recruited Clark, then aged 33, to share command of the expedition.
Expedition west
After the Louisiana Purchase in 1803, Thomas Jefferson wanted to get an accurate sense of the new land and its resources. The president also hoped to find a "direct and practicable water communication across this continent, for the purposes of commerce with Asia". In addition, Jefferson placed special importance on declaring U.S. sovereignty over the Native Americans along the Missouri River.
The two-year exploration by Lewis and Clark was the first transcontinental expedition to the Pacific Coast by the United States. They reached the Pacific twelve years after Sir Alexander Mackenzie did overland in Canada. When they left Fort Mandan in April 1805 they were accompanied by the 16-year-old Shoshone woman, Sacagawea, the wife of the French-Canadian fur trader, Toussaint Charbonneau. The Corps of Discovery made contact with many Native Americans in the Trans-Mississippi West and found them accustomed to dealing with European traders and already connected to global markets.
