What is the answer for the question: What is the full name of the person who served in the Senate from his appointment in 1964 until becoming Vice President in 1977? from the following article ?  Hubert Humphrey was a Minnesotan who became a nationally prominent politician. He first ran for mayor of Minneapolis in 1943, but lost the election to the Republican candidate by just a few thousand votes.

Other members of the Farmer-Labor Party had been considering the idea, as encouraged by Franklin D.

In 1963, President John F. Kennedy sent a comprehensive civil rights bill to Congress, based largely on the ideas that Humphrey had been placing before the Senate for the previous fifteen years.  The bill passed the House in early 1964, but passage through the Senate was more difficult, due to southern segregationists who filibustered for 75 days.  Finally, in June 1964, the Civil Rights Act of 1964 became law.  Humphrey called this his greatest achievement. Lyndon B. Johnson recruited Humphrey for his running mate in the 1964...
