Gerald Rudolph Ford, Jr. (July 14, 1913 – December 26, 2006) was the 38th President of the United States (1974–1977), and has been the only person to occupy that office who had been elected neither to the presidency nor the vice-presidency. Ford was the first person appointed to the vice presidency under the terms of the 25th Amendment, and, after serving as the 40th Vice President (1973–1974) of the United States for less than a year, became President upon Richard Nixon's resignation.
