Theodore Roosevelt

Born in New York City in 1858, Theodore Roosevelt grew up with poor health but pushed himself into a life of intense activity and study. He graduated from Harvard, wrote history and political works at a young age, and built a public career that included service in the New York legislature, the U.S. Civil Service Commission, and as assistant secretary of the navy.

Roosevelt became nationally famous after serving with the Rough Riders in the Spanish-American War. He then served as governor of New York, vice president, and, after the assassination of William McKinley in 1901, became the 26th president of the United States. In office he became known for trust-busting, a more active presidency, and major conservation efforts that helped expand the national forests, parks, and wildlife protections.

He was also an unusually productive author, publishing many books and articles on politics, history, travel, nature, and outdoor life. After leaving the White House, he continued writing, campaigning, and traveling on major expeditions, including in Africa and South America. He died in 1919, but his reputation as an energetic reformer and champion of the strenuous life has kept him a vivid figure in American history.
