Charles Warren Fairbanks was an American politician who served as a senator from Indiana from 1897 to 1905 and the 26th vice president of the United States from 1905 to 1909. He was also the Republican vice presidential nominee in the 1916 presidential election. Had the Republican ticket been elected, Fairbanks would have become the third vice president to multiple presidents, after George Clinton and John C. Calhoun.
Born in Unionville Center, Ohio, Fairbanks moved to Indianapolis after graduating from Ohio Wesleyan University. He became an attorney and railroad financier, working under railroad magnate Jay Gould. Fairbanks delivered the keynote address at the 1896 Republican National Convention and won election to the Senate the following year. In the Senate, he became an advisor to President William McKinley and served on a commission that helped settle the Alaska boundary dispute.
The 1904 Republican National Convention selected Fairbanks as the running mate for President Theodore Roosevelt. As vice president, Fairbanks worked against Roosevelt's progressive policies.
