Schoolchildren absorb at least one fact about Richard Milhous Nixon: He was the first and (so far) the only President of the United States to resign the office. Before the spectacular fall, there was an equally spectacular rise. In a half-dozen years, he went from obscurity to a heartbeat from the presidency, winning a congressional race (1946), national prominence in the Alger Hiss spy case (1948), a Senate seat (1950), and the vice presidency (1952). John F. Kennedy interrupted Nixon's assent in 1960, winning the presidency by the narrowest margin of the twentieth century.
