Historian and author Garry Wills. He looks at leadership in his new book "Certain Trumpets: The Call of Leaders" (Simon & Shuster). Wills chooses a broad spectrum of leaders--FDR, Harriet Tubman, Socrates, Martha Graham and others--and examines their leadership qualities and the bases of their success.
