LOS ANGELES -- Elizabeth Taylor, the violet-eyed film goddess whose sultry screen persona, stormy personal life and enduring fame and glamour made her one of the last of the classic movie stars and a template for the modern celebrity, died Wednesday at age 79.

She was surrounded by her four children when she died of congestive heart failure at Cedars-Sinai Medical Center, where she had been hospitalized for about six weeks, said publicist Sally Morrison.

"My mother was an extraordinary woman who lived life to the fullest, with great passion, humor, and love," her son, Michael Wilding, said in a statement.

"We know, quite simply, that the world is a better place for Mom having lived in it. Her legacy will never fade, her spirit will always be with us, and her love will live forever in our hearts."

"We have just lost a Hollywood giant," said Elton John, a longtime friend of Taylor. "More importantly, we have lost an incredible human being."

Taylor won three Academy Awards, including a special one for her humanitarian work.

One of those Oscars came for her performance in "Who's Afraid of Virginia Woolf?" She played an alcoholic shrew in an emotionally sadomasochistic marriage opposite real-life husband Richard Burton.

For all the ferocity of her screen roles and the turmoil of her life, Taylor was remembered by "Virginia Woolf" director Mike Nichols for her gentler, life-affirming side.

"The shock of Elizabeth was not only her beauty. It was her generosity. Her giant laugh. Her vitality, whether tackling a complex scene on film or where we would all have dinner until dawn," Nichols said in a statement. "She is singular and indelible on film and in our hearts."

Taylor was the most loyal of friends and a defender of gays in Hollywood when AIDS was new to the industry and beyond. But she was afflicted by ill health, failed romances (eight marriages, seven husbands) and personal tragedy.

"I think I'm becoming fatalistic," she said in 1989. "Too much has happened in my life for me not to be fatalistic."

Her more than 50 movies included portraits of innocence and of decadence, from the children's classic "National Velvet" and the sentimental family comedy "Father of the Bride" to Oscar-winning transgressions in "Who's Afraid of Virginia Woolf?" and "Butterfield 8." The historical epic "Cleopatra" is among Hollywood's greatest on-screen fiascos and a landmark of off-screen monkey business, the meeting ground of Taylor and Burton, the "Brangelina" of their day.

She played enough bawdy women on film for critic Pauline Kael to deem her "Chaucerian Beverly Hills."

A Hollywood icon

But her defining role, one that lasted past her moviemaking days, was "Elizabeth Taylor," ever marrying and divorcing, in and out of hospitals, gaining and losing weight, standing by Michael Jackson, Rock Hudson and other troubled friends, acquiring a jewelry collection that seemed to rival Tiffany's.

The London-born actress was a star at age 12, a bride and a divorcee at 18, a superstar at 19 and a widow at 26. She was a screen sweetheart and martyr later reviled for stealing Eddie Fisher from Debbie Reynolds, then for dumping Fisher to bed Burton, a relationship of epic passion and turbulence, lasting through two marriages and countless attempted reconciliations.

She was also forgiven. Reynolds would acknowledge voting for Taylor when she was nominated for "Butterfield 8" and decades later co-starred with her old rival in "These Old Broads," co-written by Carrie Fisher, the daughter of Reynolds and Eddie Fisher.

Taylor's ailments wore down the grudges. She underwent at least 20 major operations and she nearly died from a bout with pneumonia in 1990. In 1994 and 1995, she had both hip joints replaced, and in February 1997, she underwent surgery to remove a benign brain tumor. In 1983, she acknowledged a 35-year addiction to sleeping pills and pain killers. Taylor was treated for alcohol and drug abuse problems at the Betty Ford Clinic in Rancho Mirage, Calif.

Her troubles bonded her to her peers and the public and deepened her compassion. Her advocacy for AIDS research and for other causes earned her a special Oscar.

Survivors include her daughters Maria Burton-Carson and Liza Todd-Tivey, sons Christopher and Michael Wilding, 10 grandchildren and four great-grandchildren.

A private family funeral is planned later this week.
