John F. Kennedy
Millions of Americans can never forget where they were or what they were doing when they heard that John F. Kennedy was shot and killed by Lee Harvey Oswald in Dallas, Texas, on November 22, 1963. Kennedy's death and the subsequent period of mourning transfixed the nation, in part because television brought the events clearly, immediately, and constantly into American homes.
Kennedy's death ended the optimism that emanated from the youth, idealism, and energy of his administration. As the nation mourned, the Kennedy family turned to the rituals and practices of official remembrance first practiced after the assassination of Abraham Lincoln.
