Louisiana Purchase and Lewis & Clark
William Clark in Louisiana Purchase and Lewis & Clark
William Clark (1770-1838), a lifelong military man, was asked by his friend Meriwether Lewis to serve as co-leader of the Corps of Discovery on its 1804-1806 round-trip journey across the continent of the Pacific.
Clark lacked formal education but nevertheless became the expedition's primary mapmaker and journal-keeper. Clark, a steady character, provided a perfect balance for Lewis's brilliant but more erratic (and possibly bipolar) personality.
