Late Superman star Christopher Reeve's children have pledged to continue their father's search for a cure to paralysis. The actor died in 2005, nine years after he was left paralysed by a horse-riding accident. Before his death he established the Christopher Reeve Paralysis Foundation to fund research for therapies and a cure. His three children from two relationships, ALEXANDRA, 24, MATTHEW, 27 and WILL, 14, all serve on the foundation's board. Alexandra - Reeve's daughter with former partner GAE EXTON - says, "Our dad's accident really did connect us to this community: four million people in the US who are suffering from paralysis. We understand how important it is not only to find a cure but also to improve quality of life." Reeve's widow, Will's mother, DANA REEVE died from lung cancer earlier this year (06).
