Theodore Roosevelt

He was the youngest President of the United States, [5] but he is most remembered for his energy, his range of interests and achievements, his model of masculinity, and his "cowboy" image. He was a leader of the Republican Party and founder of the short-lived Bull Moose Party. Before becoming the 26th President (1901–1909) he held offices at the municipal, state, and federal level of government. Roosevelt's achievements as a naturalist, explorer, hunter, author, and soldier are as much a part of his fame as any office he held as a politician.
