Meriwether Lewis  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. Meriwether Lewis was born 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). 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 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 American Indians. 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. In 1793, Lewis graduated from Liberty Hall (now Washington and Lee University). That year he joined the Virginia militia, and in 1794 he was sent as part of a detachment 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.
