Theodore Roosevelt

By the 26th President of the United States, popularly known as T.R. or Teddy. He was also a widely respected historian, naturalist and explorer of the Amazon Basin; his 35 books include works on outdoor life, natural history, U.S. Western and political history, an autobiography and a host of other topics.

Theodore Roosevelt, Jr., also known as T.R., and to the public (but never to friends and intimates) 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. Roosevelt is most famous for his personality: his energy, his vast range of interests and achievements, his model of masculinity, and his "cowboy" persona.

Roosevelt was mostly home schooled by tutors and his parents. Biographer H. W. Brands argues that "The most obvious drawback to the home schooling Roosevelt received was uneven coverage of the various areas of human knowledge." He was solid in geography (as a result of self study during travels), and bright in history, biology, French, and German; however, he struggled in mathematics and the classical languages. He entered Harvard College on September 27, 1876; his father told him "Take care of your morals first, your health next, and finally your studies".
