Elizabeth Taylor, who passed away today from congestive heart failure at the age of 79, was a Hollywood legend known as much for her tireless humanitarian work as for her legendary screen roles. When it came to her work with HIV/AIDS-related charities, including the American Foundation for AIDS Research, better known as amfAR, and her own Elizabeth Taylor HIV/AIDS Foundation, the actress was an unstoppable force committed to doing all she could to see the public educated about the realities of the disease.

"Celebrity is not something that comes without responsibility," Taylor said. "I kept seeing all these news reports on this new disease and kept asking myself why no one was doing anything. And then I realized that I was just like them. I wasn't doing anything to help."
