THEODORE ROOSEVELT, 26TH PRESIDENT - As Vice President under President McKinley, Theodore Roosevelt assumed the office of the President upon the death of McKinley. He went on to be elected to a second term, and becoming one of our greatest presidents. He is perhaps best known for his nickname of "Teddy," his role as a "Rough Rider" in Cuba during the Spanish-American war, his construction of the Panama Canal, and his slogan "Speak softly, but carry a big stick." He supported progressive issues, environmental conservation, and the expansion of U.S. influence throughout the World. For those visiting Washington, D.C., be sure to visit Roosevelt Island which can be accessed via the Virginia side of the Potomac River, which includes a monument in its center to Theodore Roosevelt.
