He went to Harvard University and later became a rancher, New York City police commissioner, Assistant Secretary of the Navy, and fought in the Spanish-American War. Roosevelt became the 26th President of the United States in 1901 and was the first president to be a conservationist, establishing many national parks and forests and wildlife refuges. He won the Nobel Peace Prize in 1906 for helping end the Russo-Japanese War and his legacy includes being featured on Mount Rushmore.
