The first volume of Edmund Morris's biography of Theodore Roosevelt won the Pulitzer Prize. This second volume covers Roosevelt's years as American President. Theodore Roosevelt was one of the most vibrant presidents of the USA. A naturalist, adventurer, soldier and politician, Theodore Roosevelt became president in 1901, when he was not quite 43 - the youngest president in the nation's history. He built himself from a frail, asthmatic boy to become one of the most charismatic presidents in history. Responsible for radical reform, and for ensuring the construction of the Panama Canal, Roosevelt steered the US more actively into world politics, and crusaded for conservation - adding enormously to the national forests in the West.
