Born Aug. 18, 1774, in Albemarle County not far from Charlottesville, Lewis was a boyhood neighbor of Thomas Jefferson. In 1794, Lewis joined the U.S. Army and eventually rose to the rank of captain. During his time in the army he was attached to a sublegion of General "Mad Anthony" Wayne which Lt. William Clark commanded. The two men became fast friends during their adventures on a Northwest Campaign against the British and Indians. In 1801, Lewis became a private secretary to President Jefferson. Under Jefferson's direction, and with Clark by his side, Lewis planned the famous exploration for a route west to the Pacific coast. After the expedition Lewis was appointed Governor of the Louisiana Territory in 1807. He died tragically Oct. 11, 1809, at the age of 35, under ambiguous circumstances. It is speculated that personal and professional problems may have driven him to suicide, but some people believe the great western explorer was murdered.
