Millard Fillmore (January 7, 1800 - March 8, 1874) was the thirteenth President of the United States, serving from 1850 until 1853, and the last member of the Whig Party to hold that office. He was the second Vice President to assume the Presidency upon the death of a sitting President, succeeding Zachary Taylor who died of what is thought to be acute gastroenteritis or hypothermia (heat stroke). Fillmore was never elected President; after serving out Taylor's term, he failed to gain the nomination for the Presidency of the Whigs in the 1852 presidential election, and, four years later, in the 1856 presidential election, he again failed to win election as the Know Nothing Party and Whig candidate
