William Clark

William Clark (August 1, 1770 – September 1, 1838) was an American explorer, soldier, Indian agent, and territorial governor. A native of Virginia, he grew up in pre-statehood Kentucky before later settling in what became the state of Missouri. Along with Meriwether Lewis, Clark led the Lewis and Clark Expedition of 1804–1806 across the Louisiana Purchase to the Pacific Ocean, the first major effort to explore and map much of what is now the Western United States and to assert American claims to the Pacific Northwest. Before the expedition, he served in a militia and the United States Army. Afterward, he served in a militia and as governor of the Missouri Territory. From 1822 until his death in 1838, he served as Superintendent of Indian Affairs. Early life William Clark was born in Caroline County, Virginia, on August 1, 1770, the ninth of ten children of John and Ann Rogers Clark. His parents were natives of King and Queen County, and were of English and possibly Scots ancestry. The Clarks were planters in Virginia and owned several modest estates and a few slaves. They were members of the Anglican Church. Clark did not have any formal education; like many of his contemporaries, he was tutored at home. In later years, he was self-conscious about his convoluted grammar and inconsistent spelling—he spelled "Sioux" 27 different ways in his journals of the Lewis and Clark Expedition—and sought to have his journals corrected before publication. The spelling of American English was not standardized in Clark's youth, but his vocabulary suggests he was well read.
