The CIA's covert mind control program. LSD experiments on unwitting citizens. Hypnosis. Torture. And the 20,000 documents they failed to destroy.
From 1953 to 1973, the CIA conducted illegal experiments on American and Canadian citizens without their knowledge or consent. Project MKUltra used LSD, electroshock therapy, hypnosis, sensory deprivation, and psychological torture to develop mind control techniques. Subjects included mental patients, prisoners, drug addicts, and sex workers — people unlikely to be believed if they talked. In 1973, CIA Director Richard Helms ordered all MKUltra files destroyed. He missed 20,000 documents that were misfiled in the financial records. Those files exposed everything in 1977.

nytimes.comCIA set up brothels in San Francisco and New York. Unwitting johns were drugged with LSD while agents watched through one-way mirrors. Purpose: study the effects of LSD for interrogation. Ran from 1954-1966.
Dr. Donald Ewen Cameron at McGill University subjected patients to "psychic driving" — playing recorded messages for 16-20 hours a day, drug-induced comas lasting weeks, and up to 360 electroshocks. Many patients left with permanent amnesia. Canadian government later paid $100,000 settlements to survivors.
Army scientist Frank Olson was secretly dosed with LSD by Sidney Gottlieb. Days later, he "fell" from a 13th floor window. Ruled suicide. In 1994, his body was exhumed — forensic evidence showed he was likely struck in the head before the fall. Olson knew too much about CIA biological weapons testing.
44 universities participated in MKUltra research. Harvard, Stanford, Columbia, MIT, and many others accepted CIA funding through front organizations. Researchers often didn't know their true sponsor. Ted Kaczynski (the Unabomber) was a subject of Harvard's MKUltra experiments as a teenager.

Frank Olson's body exhumed. Forensic evidence suggests homicide. Manhattan DA investigates but case goes cold.
Only 20,000 of an estimated 150,000+ documents survived. What secrets did Richard Helms succeed in destroying?
MKUltra "officially" ended in 1973. But successor programs with different names may have continued. MKNAOMI, MKSEARCH, and others are poorly documented.
Records of individual subjects were destroyed. Thousands of people may never know they were experimented on.
The CIA claims the program failed to produce reliable mind control. But would they tell us if it succeeded?
