Looks like Clockwork Orange author Anthony Burgess was involved with the CIA’s MK-ULTRA project:

According to the anonymous source, Burgess became involved with the CIA while working as a Colonial Service education officer in Malaya in the 1950s.

There he became a party to trials for a mind-control process designed to trigger emotional responses in the brain using pain and pleasure ? the inspiration, it is claimed, for the chilling Ludovico Technique in A Clockwork Orange.
