One of the youngest of America's first ladies, Jackie became an icon of the era. Her beauty, fashion, beguiling family, and the cultural and historical sense she brought to the White House -- at a time when television began to shape politics -- changed how America and the world viewed the role of the first lady. "Everything about her seemed different," said Kennedy biographer Barbara Perry.
The tragedy of Dallas and the days that followed also changed how the world viewed the former Jacqueline Bouvier and her family's tragic loss.
