Ray was noted throughout his life for his generosity. To family, to friends and to a broad array of noble causes that touched his heart - spanning environmental, medical, social and political issues.

Many people have asked if they could make a charitable donation as a salute to Ray.

Ray's widow Philippa has chosen an under-funded cause that she would like to benefit from the generosity of those who wish to salute Ray. The Dementia Research Fund at University College London's Dementia Research Centre. It shares its discoveries with fellow researchers and medical centres worldwide.

If you make a donation in Ray's name we have arranged that it will be channeled specifically to fund research into PPA (Primary Progressive Aphasia) - the rare and dreadful neurological condition that afflicted Ray in his final years - and eventually robbed him of his life.
