David Thomas

David Thomas had a very challenging upbringing. His mother was an alcoholic and his stepfather was physically abusive to him. At the age of 16 he went off the rails. He got in trouble with the police, attempted suicide, tried to kill a policeman, received a court conviction and was expelled from school.

He joined the Fire Service at 20 and subsequently failed his promotion exams. He bought a book on memory in a desperate attempt to pass his exams and found he had a gift. Within 8 months of buying the book he went to The World Memory Championships and came 4th. He has since gone on to develop one of the most powerful memories in history.

He lives in Halifax, Yorkshire and also holds a US Green Card
