Elizabeth Taylor, one of the 20th Century's biggest movie stars, has died in Los Angeles at the age of 79. The double Oscar-winning actress had a long history of ill health and was being treated for symptoms of congestive heart failure. Her four children were with her when she died at Cedars-Sinai Medical Center. In a statement, her son Michael Wilding called her an extraordinary woman who lived life to the fullest. He said her legacy will never fade. Elizabeth Taylor's most famous films included National Velvet, Cleopatra and Who's Afraid of Virginia Woolf? She was equally well-known for her glamour and film partnership with Richard Burton, one of her seven husbands. In her prime, she was one of the world's greatest actresses and most beautiful women. Her colourful private life, screen success and Aids charity work ensured she was never far from the spotlight since finding fame at the age of 12. The peak of her film career came in the 1950s and 1960s, with four Oscar nominations in a row from 1958 to 1961. Her second Oscar came in 1967 for Who's Afraid of Virginia Woolf?, one of 12 films with Burton. She met the actor while filming 1963's Cleopatra. Her health problems began with a fall while filming her first hit film, National Velvet, which led to a lifetime of back problems. But she continued to campaign for her Aids charity, which she set up in 1991 after the death of her friend and co-star Rock Hudson.
