There is a Web of Stories video series of Brian Aldiss remembering his life.
It consists of several pages - each containing an index of ten short videos. They are episodic but are not in strict chronological order - as he jumps about in his reminiscences. One video did clarify that an apparently improbable part of the plot in "The Hand-Reared Boy" was autobiographical.
His childhood was quite miserable - with both parents lacking affection for him. His mother's brother was a major positive influence on him during a short stay at his grandmother's house - just before was packed off to boarding school at the age of 5.
