Thomas Jefferson (1743-1826)
Through the achievements of early pioneers and settlers, of whom Daniel Boone is the type, the region lying between the Alleghany Mountains and the Mississippi River came into the possession of the United States. In a very different way did the territory lying between the Mississippi River and the Rocky Mountains become a part of the national domain. It was acquired not by exploration or settlement, but by purchase, and the man most intimately associated with this purchase was Thomas Jefferson.
