Friends and colleagues remembered Elizabeth Taylor not only as a Hollywood icon and screen legend, but for her revered generosity.
"Elizabeth, on every level, was a mensch. Kind, generous, brave," Taylor's Blue Bird co-star Jane Fonda said.
Eva Marie Saint said she has "wonderful memories" of working with Taylor in 1957's Raintree County and 1965's The Sandpiper.
"I'll always have a soft spot in my heart for Elizabeth Taylor," Saint said. "She was an incredible talent, and yes, she had those unforgettable eyes. I greatly admire her humanitarian efforts which have touched so many lives. Elizabeth was a very dear, generous and loving lady."
Taylor's legacy in film is perhaps only surpassed by her activism. The actress formed an AIDS research project following the death of her friend Rock Hudson in the 1980s. She later joined forces with Dr. Mathilde Krim to create The American Foundation for Aids Research (amfAR). In 1991, she created her own foundation, the Elizabeth Taylor AIDS Foundation (ETAF).
"Dame Elizabeth was without doubt one of the most inspirational figures in the fight against AIDS. She was among the first to speak out on behalf of people living with HIV when others reacted with fear and often outright hostility," amfAR said in a statement. "For 25 years, Dame Elizabeth has been a passionate advocate of AIDS research, treatment and care. She has testified eloquently on Capitol Hill, while raising millions of dollars for amfAR. Dame Elizabeth's compassion, radiance, and generosity of spirit will be greatly missed by us all. She leaves a monumental legacy that has improved and extended millions of lives and will enrich countless more for generations to come."
Larry King and George Michael were among the stars who paid tribute to Taylor's AIDS advocacy.
"Elizabeth Taylor was a great friend, a great star and one gutsy woman," King tweeted. "She was so special.You won't see the likes of her again ... She was first major celeb in the AIDS battle and she made it her cause ..."
"Such a sad day, Elizabeth Taylor was the last of the Hollywood greats, and a fantastically charming woman," Michael tweeted. "She also did a great deal in the last 25 years to help the world deal with the HIV epidemic. I am proud to have known her if only a little. She was also the only person I've ever met that had violet eyes. They were genuinely violet. So beautiful."
Kim Kardashian, with whom Taylor conducted her final interview in February's Harper's Bazaar, tweeted that she was saddened by Taylor's death.
"She will always be my idol!" Kardashian tweeted.
Martin Landau (Taylor's Cleopatra co-star) said: "It's a terrible loss. A unique talent and a singularly spectacular individual."
Simpsons executive producer Al Jean (Taylor appeared twice on the show — once as herself and once as the voice of Maggie) said: "The Simpsons were greatly saddened to learn of the passing of their legendary friend Elizabeth Taylor. In particular, Maggie is speechless."
Debbie Reynolds (whose husband Eddie Fisher left her for Taylor) said: "It was a long productive career, and she was the most glamorous and sexual star of our generation. No one else could equal Elizabeth's beauty and sexuality. Women liked her and men adored her, and her love for her children is enduring. She was a symbol of stardom. Her legacy will last."
Barbra Streisand said: "It's the end of an era. It wasn't just her beauty or her stardom. It was her humanitarianism. She put a face on HIV/AIDS. She was funny. She was generous. She made her life count."
Elton John said: "We have just lost a Hollywood giant. More importantly, we have lost an incredible human being."
Whoopi Goldberg said: "Today my friend Elizabeth Taylor passed away. Oddly, we all knew this day was coming but still her passing took my breath away. She was a funny, loud, joke-tellin', diamond-loving, fantastic woman. She played a big role in shaping my life as Whoopi Goldberg. It really is the end of an era."
