Hamilton Bertie Gibson, generally known as Tony Gibson, was a British psychologist, anarchist, and model. He became known for his objection to Great Britain's involvement in World War II and his subsequent imprisonment for being an unregistered conscientious objector.
In 1939, while working as a life model for art students, he was selected to model for Brylcreem advertisements. During the Battle of Britain he was depicted wearing an RAF uniform, despite the fact that by then he was in prison as a conscientious objector. After serving three sentences he agreed to work as an ambulance driver and then as an agricultural labourer.
After the war he worked at Burgess Hill School teaching woodwork and biology. In the 1950s he studied sociology at the London School of Economics and psychology at the Institute of Psychiatry, following which he undertook research at the Institute of Criminology at the University of Cambridge.
During the period at Cambridge, he developed the Spiral Maze, a psychomotor test that was able to distinguish between normal boys and those who were maladjusted or delinquent. This test has also been found to be useful in assessing psychomotor impairment due to drugs.
