Why should we know the name William Clark of the Lewis and Clark Expedition and not know the name George Rogers Clark older brother of William? It was through the elder brother's recommendation that Thomas Jefferson assigned William Clark to explore the northern portion of the Louisiana Purchase. George Rogers Clark was the genius of that enterprising Clark family. He was the Clark of another Northwest who won all the area from Pittsburgh to the source of the Mississippi. But for George Clark the borders of Canada might be on the Ohio and Allegheny Rivers. He was also a brilliant officer in Washington's Army. This is the story of George Rogers Clark, a most fascinating and brilliant man. Illustrated. Contents: Background; Formative Years; Into His Own; High Action; Vision Fulfilled; Maps.
