The oldest child of former US President Theodore Roosevelt, she was an American socialite who famously quipped, "If you haven't got anything nice to say about anybody, come sit next to me."
She became a fashion icon and instant celebrity at age seventeen due to her father's assumption of office.
During the Kennedy and Johnson administrations she became a Democrat, and she identified herself as a hedonist during a 60 Minutes interview.
Her parents were President Theodore Roosevelt and Alice Hathaway Lee.
Her fifth cousin Franklin D. Roosevelt served as the 32nd President of the United States.
