Hypomaniacs, all? The Boston Globe
In his book ''The Hypomanic Edge,'' psychologist John D. Gartner argues that many of the most prominent leaders in American history experienced a mild, benign form of mania that turned them into superachievers. What follow are some of his rough diagnoses.

John Winthrop
''John Winthrop organized the Great Migration in 1629, when he became convinced that England's sins had provoked God beyond his breaking point . . . . You have to be at least a little manic to be certain you know that the Apocalypse is now.''

Craig Venter
''Without his hypomanic temperament, Craig Venter wouldn't have pushed the field [of genetics] to new heights or pushed his colleagues' buttons.''

Alexander Hamilton
''Hamilton's hypomania was an essential ingredient in his accomplishments. And his accomplishments were an essential ingredient in the creation of America.''

Henry Ford
''His impatience was the secret to his success. The motor inside of him revved so quickly that the world around him seemed maddeningly slow, and he wanted the world to catch up.''
