August 18

Explorer Meriwether Lewis, who joined William...

Clark to blaze a trail across the continent to the Pacific Ocean, was born on August 18, 1774 near Charlottesville, Virginia. Lewis grew up roaming the woods of Albemarle County, near Monticello, the home of Thomas Jefferson. When Jefferson assumed the presidency in 1801, he selected Lewis as his private secretary. Two years later, Jefferson appointed Lewis to lead an exploration of the Louisiana Purchase--the vast territory the U.S. acquired from France in 1803.

Lewis and Clark set out from St. Louis on May 14, 1803, heading northwest on the Missouri River. They hoped to discover a Northwest Passage--a water route to the Pacific Ocean. The expedition wintered in present-day North Dakota, traveled to what is now Montana, and reached the mouth of the Columbia River in present-day Washington before returning to St. Louis on Sept. 23, 1806.

Lewis and Clark kept a detailed journal of their three-year journey. Published in 1809, the journals generated excitement about the unknown region and diminished Easterners' fears about venturing beyond the Mississippi. York, a slave and childhood companion of William Clark, also participated in the expedition. In the process of compiling a short history of African Americans in Omaha, Nebraska for the WPA interview "Arthur Goodlet," Fred D. Dixon remembered the "Negro slave named York, the property of Clark, [who] was with Lewis and Clark when they came to the place where Omaha now stands, in 1805." At the successful completion of the expedition, York tried to persuade Clark to grant his freedom in return for the service he had rendered to the nation. Although Clark refused at first, about ten years later he did free York.

For their part in the three-year adventure, Lewis and Clark each received 1,600 acres of public land. Popular acclaim led to Lewis's assumption of the governorship of the Louisiana Territory and Clark's appointment as governor of the Missouri Territory. Meriwether Lewis died Oct. 11, 1809.
