Reeve, a singer-actress who gave up some of her own career to be one of the nations best-known caregivers, died late Monday at Memorial Sloan-Kettering Medical Center, said Kathy Lewis, president of the Christopher Reeve Foundation. Reeve had succeeded her husband as chair of the foundation, which funded research into spinal-cord paralysis cures. She announced in August that, while she wasnt a smoker, she had been diagnosed with lung cancer. Lewis visited Reeve in the hospital Friday and said Reeve was tired but with her typical sense of humor and smile, always trying to make other people feel good, her characteristic personality. She was a woman with an incredible heart who really put herself out there to help people with disabilities and especially those who are caregivers something she knew a lot about, Lewis said. Reeves' grace and courage under the most difficult of circumstances was a source of comfort and inspiration to all of us, Lewis added in a statement. Four months ago, at a fundraising gala for the foundation, Reeve looked healthy in a long, formal gown and said she was responding well to treatment and her tumor was shrinking. Im beating the odds and defying every statistic the doctors can throw at me, Reeve said then. My prognosis looks better all the time.
