Nelson Rockefeller
When Richard Nixon resigned (quit) as president on August 9, 1974, Vice President Gerald Ford became the president. On August 20, Ford chose Rockefeller to be the next vice president of the United States. He was chosen out of three other people; the other two were Donald Rumsfeld, the then-United States Ambassador to NATO, and George H.W. Bush, the then-chairman of the Republican National Convention (RNC). Bush would later become vice president from 1981 to 1989, and president from 1989 to 1993.
