Roger Kennedy's most driving current interest is the long-term effects of long-term abuse of natural systems, and he means seriously long term. Kennedy knows politics. For decades a major player himself in Washington DC, he has written redefining biographies of Thomas Jefferson, Alexander Hamilton, and Aaron Burr. Kennedy knows history. Besides writing and hosting a number of television series on American history, he wrote Rediscovering America and Hidden Cities: The Discovery and Loss of Ancient North American Civilization.
