Theodore Roosevelt, Jr., also known as T.R., and to the public (but never to friends and family) as Teddy, was the twenty-sixth President of the United States, and a leader of the Republican Party and of the Progressive Movement. He became the youngest President in United States history at the age of 42. He served in many roles including Governor of New York, historian, naturalist, explorer, author, and soldier (posthumously awarded the Medal of Honor in 2001 for his role at the Battle of San Juan Hill in the Spanish-American War). Roosevelt is most famous for his personality: his energy, his vast range of interests and achievements, his model of masculinity, and his "cowboy" persona.
