"Experiments were often conducted without the subjects' knowledge or consent. In some cases, academic researchers being funded through grants from CIA front organizations were unaware that their work was being used for these purposes.
A precursor of the MK-ULTRA program began in 1945 when the Joint Intelligence Objectives Agency was established and given direct responsibility for Operation Paperclip. Operation Paperclip was a program to recruit former Nazi scientists. Some of these scientists studied torture and brainwashing, and several had just been identified and prosecuted as war criminals during the Nuremberg Trials.
Several secret U.S. government projects grew out of Operation Paperclip. These projects included Project CHATTER (established 1947), and Project BLUEBIRD (established 1950), which was later renamed to Project ARTICHOKE in 1951. Their purpose was to study mind-control, interrogation, behavior modification and related topics."
This sounds like the X-Files but the Federal Govt of the USA actually sponsored such experiments on it's own citizens...
