Gerald Rudolph Ford Jr. (born Leslie Lynch King Jr.; July 14, 1913 – December 26, 2006) was an American politician who served as the 38th president of the United States from August 1974 to January 1977. Before his accession to the presidency, Ford served as the 40th vice president of the United States from December 1973 to August 1974. Ford is the only person to have served as both vice president and president without being elected to either office by the Electoral College. Ford's transition chairman and first Chief of Staff was former congressman and ambassador Donald Rumsfeld. In 1975, Rumsfeld was named by Ford as the youngest-ever Secretary of Defense. Ford chose a young Wyoming politician, Richard Cheney, to replace Rumsfeld as his new Chief of Staff; Cheney became the campaign manager for Ford's 1976 presidential campaign.
