Arthur M. Schlesinger, Jr., (1917-2007) was the preeminent political historian of our time. For more than half a century, he was a cornerstone figure in the intellectual life of the nation and a fixture on the political scene. He won two Pulitzer prizes for "The Age of Jackson" (1946) and "A Thousand Days" (1966), and in 1988 received the National Humanities Medal. He published the first volume of his autobiography, "A Life in the Twentieth Century", in 2000.
