Meriwether Lewis (August 18, 1774–October 11, 1809) was an American explorer, soldier, and public administrator, best known for his role as the leader of the Lewis and Clark Expedition.
William Clark (August 1, 1770 – September 1, 1838) was an American explorer, soldier, Indian agent, and territorial governor. A native of Virginia, he would also grow up in pre-statehood Kentucky before later settling in what later became the state of Missouri. Along with Meriwether Lewis, Clark led the Lewis and Clark Expedition of 1803 to 1805.
The Lewis and Clark Expedition was the first American overland expedition to the Pacific coast and back. Originally intended to determine exactly what was obtained in the Louisiana Purchase, the expedition laid much of the groundwork for the Westward Expansion of the United States.
