Kennedy, was assassinated at 46 on Nov. 22, 1963. But even in the midst of unimaginable tragedy, she had a key focus: to ensure that his legacy endured. And to do that, she spun a fantasy that has only grown in the five decades since. On Nov. 29, 1963, four days after her husband’s burial, the widowed mother of two invited Life magazine journalist Theodore H. White to the Kennedy family compound in Hyannis Port, Massachusetts. There, Jackie, then just 34, crafted a glittering fairytale about JFK’s 1,000 days in the White House that continues to captivate the nation. The inspiration? JFK’s favorite Broadway musical, Camelot — the story of mythical world, ruled by King Arthur, where goodness reigned supreme. “Don’t let it be forgot, that for one brief, shining moment there was Camelot,” Jackie told White, quoting from the musical. In PEOPLE’s Dec. 2016 cover story, those who knew the iconic First Lady offer insight into what she shrewdly viewed as an opportunity to ensure that her husband’s achievements would never be forgotten.
