The Keller Machine was a device created by the Master under the alias of Emil Keller. In the machine's core was a living organism, a psychic parasite. It was designed to extract from human brains the negative impulses that caused anti-social behaviour, and was therefore a more humane alternative to executing criminals. It could also be used to kill by turning the victim's worst fears against them.
After being used to process 112 cases in Switzerland, Professor Keller, with the assistance of Professor Kettering, had it installed in Stangmoor Prison. Its subsequent use on George Patrick Barnham was witnessed by several people, including the Third Doctor, Jo Grant, Arthur Linwood, (as featured in the Doctor Who story The Mind of Evil)
