Gerry Anderson, who devised 'Thunderbirds' and 'Captain Scarlet', decided to donate his brain to dementia research after telling his son that the drugs he was taking were having little effect.
The television director, pictured, died on St Stephen's Day, aged 83, a little over a year after being diagnosed with Alzheimer's.
He came to the decision after discussing the matter with his wife Mary and their son Jamie. Jamie (27) said: "He was very keen that he should not be buried. He saw it as a waste of space."
Jamie raised the possibility of his father's organs being donated for research when he died.
The family looked into the matter with the Alzheimer's Society, which put them in touch with a project called Brains for Dementia Research.
His brain would be used to help develop a new generation of Alzheimer's drugs, doctors said. (© Daily Telegraph, London)
