Humphrey, Hubert Horatio (1911-1978), served as vice president of the United States under President Lyndon B. Johnson, and was the Democratic presidential nominee in 1968. Humphrey lost to former Vice President Richard M. Nixon. Before his election as vice president in 1964, Humphrey had been elected to the U.S. Senate three times. He was the first Democrat ever elected to the Senate from Minnesota. In 1970, he was again elected to the Senate, and he was reelected in 1976. In 1977, the Senate made Humphrey the deputy president pro tempore of the Senate, a new post. The title will be given to all former Presidents and vice presidents who later become members of the Senate.
