Who was the only man to hold the nations top two offices without being elected either?

Gerald Ford is the only man to hold the nation's top two offices—the presidency and the vice presidency—without being elected to either position. He became vice president in 1973 after Spiro Agnew resigned, and then he ascended to the presidency in 1974 following Richard Nixon's resignation. Ford was appointed to both roles, making him unique in American political history.
