The code name for a covert mind-control and chemical interrogation research programme, run by the Office of Scientific Intelligence. The programme began in the early 1950s, continuing at least through the late 1960s, using US citizens as test subjects. Project MK-ULTRA was brought first to wide public attention in 1975 by Congress and by the Rockefeller Commission. Investigative efforts were hampered by the fact that CIA Director Richard Helms ordered all MK-ULTRA files destroyed in 1973. Although the CIA insisted that MK-ULTRA-type experiments were abandoned, CIA veteran Victor Marchetti has stated in various interviews that the agency routinely conducts disinformation campaigns and that CIA mind control research continued. In a 1977 interview, Marchetti specifically called the CIA claim that MK-ULTRA was abandoned a “cover story”.
Conspiracy theorists believe that MK-ULTRA was behind many so-called black-ops: Lawrence Teeter, the attorney for Sirhan Sirhan, the man convicted of the assassination of Robert Kennedy, pictured, believed Sirhan was operating under MK-ULTRA mind control techniques. Furthermore, Jonestown, the location in Guyana where members of the Jim Jones cult and Peoples Temple committed mass suicide, was thought to be a test site for MK-ULTRA medical experiments.
