Christopher Hutton
Christopher William Clayton Hutton (1893–1965) a soldier, airman, journalist and inventor, was recruited as an intelligence officer to work for MI9, a branch of the British Military Intelligence, during the Second World War. Known as 'Clutty' to his friends, he was engaged towards the end of 1939 by the War Office to work under Major (later Brigadier) Norman Crockatt, in order to set up and run operations to create and distribute escape and evasion aids for Allied servicemen. Hutton's small team identified suitable manufacturers, ensured supplies and devised methods by which the concealed aids could be sent to prisoner of war camps.
List of Doctor Who henchmen
Once Lytton's treachery to the Cybermen was exposed, the Cyber Controller ordered that Lytton undergo the cyber-conversion process. When the Doctor tried to free Lytton from his fate as a Cyberman, a partially converted Lytton died fighting the Cyber Controller, who snapped his neck. The Doctor later admitted that he had badly misjudged Lytton, though their encounters had been severely limited.
