Known as the “Happy Warrior,” Hubert Humphrey represented Minnesota in the Senate from 1949 to 1964, presided over the Senate as vice president from 1965 to 1969, and then returned to the Senate again in 1971. A powerful and influential advocate of civil rights, Humphrey served as floor manager for the Civil Rights Act of 1964. He was also the first to propose creation of a Peace Corps and to press for a nuclear test ban treaty with the Soviet Union. After he lost his race for president in 1968, Humphrey returned to the Senate, where he worked for enactment of the Humphrey-Hawkins Full Employment and National Growth bill, which Congress passed after his death. Humphrey died on January 13, 1978, and was accorded the honor of lying in state in the Capitol Rotunda on January 14-15. A poll of congressional staff ranked him as the most effective legislator of his generation. In 2011 the Senate passed a special resolution to commemorate the centennial of Humphrey’s birth.
