Theodore Roosevelt's Letters to His Children

According to Wikipedia: "Theodore Roosevelt (October 27, 1858 January 6, 1919), also known as T.R., and to the public (but never to friends and intimates) as Teddy, was the 26th President of the United States. A leader of the Republican Party and of the Progressive Party, he was a Governor of New York and a professional historian, naturalist, explorer, hunter, author, and soldier. He is most famous for his personality: his energy, his vast range of interests and achievements, his model of masculinity, and his "cowboy" image. Originating from a story from one of Roosevelt's hunting expeditions, teddy bears are named after him."
