The life of Jacqueline Bouvier Kennedy Onassis was filled with drama, beauty, grace, and style. On the arm of the dashing young senator from Massachusetts-the man who would be President-she captured the nation's Imagination, and then its heart. LIFE magazine was there for every chapter in her thrilling journey; she made the magazine's cover years before she made It to the White House. Here, in a pictorial biography featuring the work of several of LIFE's most famous shooters, we re-visit not only the glorious years of Camelot in Washington, but also Jackie's later Life as a dedicated and proud mother to John Jr, and Caroline in New York City.
