On September 14th 1901, Theodore "Teddy" Roosevelt, vice president of the United States, become the country's 26th President, following the death of William McKinley, Jr. after the latter was shot on September 6th.
Teddy Roosevelt was one of the more interesting, and talented, of the later US Presidents. This is not a man who only served as a politician, although he also served as Governor of New York. Instead, he served in the military, helped form the Rough Riders, a volunteer cavalry regiment that fought in the Spanish-American War, and was a prolific author on many different subjects, due to the many subjects he was passionate about. He certainly wasn't as bland, or a purely political animal, as many political leaders are these days.
