Hubert Horatio Humphrey Jr. (May 27, 1911 - January 13, 1978) was an American politician who served as the 38th Vice President of the United States from 1965 to 1969. He twice served in the United States Senate, representing Minnesota from 1949 to 1964 and 1971 to 1978. He was the Democratic Party's nominee in the 1968 presidential election, losing to Republican nominee Richard Nixon.
Humphrey and his running mate, Ed Muskie, who had not entered any of the 13 state primary elections, went on to win the Democratic nomination at the party convention in Chicago, Illinois even though 80 percent of the primary voters had been for anti-war candidates, the delegates had defeated the peace plank by 1,567 3/4  to 1,041 1/4 . Unfortunately for Humphrey and his campaign, in Grant Park, just five miles south of International Amphitheater convention hall (closed 1999), and at other sites near downtown Chicago, there were gatherings and protests by the thousands of antiwar demonstrators, many of whom favored McCarthy, George McGovern, or other "anti-war" candidates. These protesters - most of them young college students - were attacked and beaten on live television by Chicago police, actions which merely amplified the growing feelings of unrest in the general public.  Humphrey's inaction during these activities along with President Johnson and Chicago Mayor Richard Daley's behind the scenes convention influencing, public backlash from securing the presidential nomination without entering a single primary, as well as Humphrey refusal to meet McCarthy half way on his demands, resulting in McCarthy's lack of full endorsement of Humphrey, highlighted turmoil in the Democratic party's base that proved to be too much for Humphrey to overcome in time for the general election. The combination of the unpopularity of Johnson, the Chicago demonstrations, and the discouragement of liberals and African-Americans when both Robert F. Kennedy and Martin Luther King Jr. were assassinated during the election year, were all contributing factors that caused him to eventually lose the election to former Vice President Nixon.  Although he lost the election by less than 1% of the popular vote, 43.4% for Nixon (31,783,783 votes) to 42.7% (31,271,839 votes) for Humphrey, with 13.5% (9,901,118 votes) for George Wallace, Humphrey carried just 13 states with 191 electoral college votes. Richard Nixon carried 32 states and 301 electoral votes, and Wallace carried 5 states in the South and 46 electoral votes (270 were needed to win). In his concession speech, Humphrey said: "I have done my best. I have lost, Mr. Nixon has won. The democratic process has worked its will."

who were the protesters?

antiwar demonstrators,

IN: Spielberg was born on December 18, 1946 in Cincinnati, Ohio. His mother, Leah (nee Posner, later Adler; January 12, 1920 - February 21, 2017), was a restaurateur and concert pianist, and his father, Arnold Spielberg (born 1917), was an electrical engineer involved in the development of computers. His family was Orthodox Jewish. Spielberg's paternal grandparents were Jewish Ukrainian immigrants who settled in Cincinnati in the 1900s; his grandmother was from Sudylkiv, while his grandfather was from Kamianets-Podilskyi.

A collector of film memorabilia, Spielberg purchased a balsa Rosebud sled from Citizen Kane (1941) in 1982. He bought Orson Welles's own directorial copy of the script for the radio broadcast The War of the Worlds (1938) in 1994. Spielberg has purchased Academy Award statuettes being sold on the open market and donated them to the Academy of Motion Picture Arts and Sciences, to prevent their further commercial exploitation. His donations include the Oscars that Bette Davis received for Dangerous (1935) and Jezebel (1938), and Clark Gable's Oscar for It Happened One Night (1934).  Spielberg is a major collector of the work of American illustrator and painter Norman Rockwell. A collection of 57 Rockwell paintings and drawings owned by Spielberg and fellow Rockwell collector and film director George Lucas were displayed at the Smithsonian American Art Museum July 2, 2010 - January 2, 2011, in an exhibition titled Telling Stories.  Spielberg is an avid film buff, and, when not shooting a picture, he will watch many films in a single weekend. He sees almost every major summer blockbuster in theaters if not preoccupied and enjoys most of them.  Since playing Pong while filming Jaws in 1974, Spielberg has been an avid video gamer. Spielberg played many of LucasArts adventure games, including the first Monkey Island games. He owns a Wii, a PlayStation 3, a PSP and Xbox 360, and enjoys playing first-person shooters such as the Medal of Honor series and Call of Duty 4: Modern Warfare. He has also criticized the use of cutscenes in games, calling them intrusive, and feels making story flow naturally into the gameplay is a challenge for future game developers.

Did he purchase any other film relics?
