Few presidents have embodied the American spirit as fully as Thomas Jefferson. He was the originator of so many of the founding principles of American democracy. Politically, he shuffled off the centralized authority of the Federalists, working toward a more diffuse and minimalist leadership. He introduced the bills separating church and state and mandating free public education. He departed from the strict etiquette of his European counterparts, appearing at state dinners in casual attire and dispensing with hierarchical seating arrangements. Jefferson initiated the Lewis and Clark expedition and seized on the crucial moment when Napoleon decided to sell the Louisiana Territory, thus extending the national development. In this compelling examination, distinguished historian Joyce Appleby captures all of the richness of Jefferson's character and accomplishments.
