President George W. Bush provides the into to this 2-part look at one of America's most beloved presidents. As President, Teddy Roosevelt tested and extended the limits of the White House like no other before him or since.

He was 42 when he took office--the youngest man ever to become President. And there is a strong case to be made that he did more with the office than anyone else in history. Had he only served one term, Theodore Roosevelt would have left an indelible mark on America.
