CIA and Air Force coordinate on behavioral research

CIA document CIA-RDP80R01731R003500150016-5 is produced in September, cataloguing active psychological warfare research programs inside the U.S. Air Force. The document confirms formal CIA and Air Force coordination on behavioral research three years before MKUltra is authorized.

1950
ARTICHOKE
Project BLUEBIRD initiated

The CIA initiates Project BLUEBIRD in response to concerns about Soviet and Chinese advances in interrogation techniques. BLUEBIRD investigates hypnosis, drug administration, and their combination as tools for behavioral control. It is the first program in the chain that leads to ARTICHOKE and MKUltra.

1951
ARTICHOKE
Project ARTICHOKE begins

Project BLUEBIRD is reorganized and renamed Project ARTICHOKE under the CIA Office of Scientific Intelligence. The program expands its research scope to include the development of a courier capability and the systematic testing of combined hypnotic and pharmacological interrogation protocols.

1952
ARTICHOKE
ARTICHOKE Team conducts overseas hypnosis interrogations — total amnesia produced

Between June 4 and June 18, 1952, the I&SO Artichoke Team conducts special interrogations at a guarded overseas safehouse on two subjects. Both subjects are transported with eyes taped shut and wearing dark glasses. In Case 1, total amnesia is produced in the professional opinion of the team. In Case 2, total amnesia is produced on the second day following sodium pentothal and Desoxyn administration. The subjects' dispositions after the operations are described as outside the Artichoke Team's responsibility. The team recommends the subject in Case 1 be held in prison for up to two years before release. Confirmed in CIA FOIA document 12884836.

1952
ARTICHOKE
ARTICHOKE Team recommends windowless vehicle for future subject transport

The July 3, 1952 Artichoke Cases report recommends that CIA overseas offices maintain a windowless ambulance or delivery truck as standard equipment for transporting subjects without risk of observation from outside or by the subjects themselves. The recommendation follows the June 1952 operation in which subjects were transported with eyes taped shut and dark glasses to prevent recognition by local populations.

1953
Montauk AFS
Montauk AFS incorporated into SAGE network

On 1 December 1953 Montauk Air Force Station's site designation changes to LP-45. The installation is incorporated into the permanent Air Defense Command network and begins integration with the Semi-Automatic Ground Environment air defense system.

1953
MKUltra
MKUltra authorized

CIA Director Allen Dulles authorizes Project MKUltra on April 13, 1953. ARTICHOKE is formally subsumed. MKUltra expands to approximately 150 subprojects across more than 80 institutions, adding LSD, sensory deprivation, and electromagnetic signal research to the methods inherited from ARTICHOKE.

1953
MKUltra
Frank Olson administered LSD without consent

Frank Olson, a U.S. Army biological weapons researcher, is administered LSD without his knowledge at a CIA retreat in November. Nine days later he falls from a window of the Statler Hotel in New York City. His death is ruled a suicide.

1963
MKUltra
CIA Inspector General recommends termination of unwitting testing on U.S. citizens

Inspector General J.S. Earman delivers a Top Secret report to the Director of Central Intelligence recommending termination of the covert testing program. The report states that no effective cover story exists, that present practice is to maintain no records of the planning and approval of test programs, and that existing checks and balances do not afford senior CIA management adequate protection against the high risks involved. The report is prepared in one copy only.

1969
