What Was Project MK Ultra?

Project MK Ultra was a real, CIA-run mind control program that ran from 1953 to 1973 under chemist Sidney Gottlieb. Approved by CIA Director Allen Dulles, it tested LSD on prisoners, patients and unwitting citizens. Declassified records confirmed it in the 1970s. It is not a theory. It happened.

The CIA does not dispute that MK Ultra happened. Director Richard Helms destroyed most of the paperwork in 1973, and what survived only surfaced because it had been misfiled. What is still argued is how far it went, who it hurt, and whether one scientist’s death was ever explained.

What was Project MK Ultra?

Project MK Ultra was a covert CIA program approved by Director Allen Dulles in 1953 and run by chemist Sidney Gottlieb until roughly 1973. It funded more than 150 documented experiments, testing LSD, hypnosis and sensory deprivation on subjects who often did not know they were part of a study.

The program grew out of Cold War paranoia. After the Korean War, US officials feared Soviet, Chinese and North Korean interrogators had learned to brainwash American prisoners of war, and wanted the same capability in reverse. Two earlier CIA programs, Bluebird and Artichoke, tested hypnosis and drugs on a smaller scale before folding into MK Ultra in 1953. Dulles handed daily control to Gottlieb, a chemist and poison specialist, and kept the operation deliberately compartmentalized: by the hosts’ count, only around a dozen people ever had the full picture. The origin story is covered start to finish in the MK Ultra origin episode.

MK Ultra was never one experiment. It was an umbrella for dozens of individually run subprojects, some handled directly by CIA staff and others funneled through outside researchers who did not always know where the money came from. Two of the most extreme, covered below, were Operation Midnight Climax and the Canadian experiments at Montreal’s Allan Memorial Institute. The CIA wound the program down around 1973, the same year most of its paperwork was destroyed, just as the Watergate scandal made Washington nervous about what else might surface. That is why nobody has ever put a hard number on how many people were dosed.

Was MK Ultra real?

Yes. Project MK Ultra is documented fact, not a theory. Declassified CIA records, the 1975 Rockefeller Commission and Church Committee reports, and 1977 Senate testimony about a surviving cache of files all confirm it. On this question, the record and the theory are the same thing.

The paperwork nearly vanished: the 1973 order wiped out most of MK Ultra’s records, and the program stayed buried for a year. That changed in 1974, when the New York Times reported the CIA had illegally spied on and experimented on American citizens, pushing Congress and the Ford administration to open the Church Committee and Rockefeller Commission investigations. Their 1975 findings confirmed the CIA and Department of Defense had run drug experiments on both consenting and unwitting subjects. In 1977, CIA Director Stansfield Turner testified that about 20,000 pages of MK Ultra material had survived, misfiled with financial records and found through a Freedom of Information Act request.

That confirmation matters more here than on almost any other case this podcast covers. Most entries in our famous conspiracy theories roundup start with a gap in the record that gets filled with speculation. MK Ultra runs the other way: the government’s own surviving files describe the program in its own words. Gottlieb testified before Congress in the 1970s under a grant of immunity and claimed little memory of the specifics, but the paper trail no longer depended on his memory by then. In 1976, President Gerald Ford issued an executive order banning drug experiments on human subjects without signed, witnessed consent.

These are all declassified documents, meaning it’s all documented, like all this stuff happened, they got the receipts.

the guys, on the record

What did the CIA actually do to people?

The CIA dosed prisoners, mental patients, prostitutes, its own employees and members of the public with LSD, often without consent. Documented cases include a Kentucky patient kept on LSD for 174 days and a Canadian doctor using electroshock at up to 40 times normal power.

Senator Ted Kennedy read the scope into the Congressional record in 1977: more than 30 universities and institutions took part in a testing program that reached unwitting subjects at every social level, high and low. Most sessions ran between 1953 and 1964, inside universities, hospitals and prisons across the United States and Canada. Military personnel who received the drug were reportedly warned they would face a court martial if they told anyone what had happened to them. The agency also dosed its own case officers and doctors without warning, partly to study how someone behaves with no idea a drug is coming their way.

Operation Midnight Climax ran CIA safe houses in San Francisco, Mill Valley and New York from 1954 into the mid 1960s, where prostitutes on the payroll lured men in and dosed them with LSD while officers watched through one way glass. In Montreal, psychiatrist Donald Ewen Cameron ran a CIA funded program at the Allan Memorial Institute that put patients into weeks-long drug induced comas, played looping tape messages at them, and used electroshock far above normal power. Patients came out with amnesia, some no longer able to recognize their own families. Canada later settled with 127 of Cameron’s victims for about 100,000 dollars each.

Who was Sidney Gottlieb?

Sidney Gottlieb was the CIA chemist who ran Project MK Ultra from 1953 under Director Allen Dulles. He personally oversaw the LSD testing, approved the drugging of unwitting subjects, and later testified to Congress under immunity. He was never charged with a crime and died in 1999.

Gottlieb joined the CIA in 1951 and headed its Technical Services division, the unit that built the agency’s poisons, disguises and interrogation tools. Journalist Stephen Kinzer profiled him in a 2019 book titled Poisoner in Chief, drawing on declassified records to trace his role in the program. Gottlieb recruited outside researchers and personally approved specific tests. In November 1953, at a retreat with colleagues at a cabin on Deep Creek Lake in Maryland, he spiked the group’s after dinner drinks with LSD without telling them. One of the men at that retreat was Frank Olson, whose story is covered in detail below.

Gottlieb had already retired from the CIA by the time investigators caught up with him. He testified before Congress in the 1970s under a grant of immunity and said he had little memory of the specifics, despite having run the program himself. No criminal charges were ever filed against him, and he died in 1999 at age 80. Unlike most figures this podcast covers, there is little dispute about what Gottlieb’s job actually was. What still gets argued is the man behind it: a Cold War patriot in his own telling, or, as the hosts put it, something closer to the villain of the story.

What happened to Frank Olson?

Frank Olson was an Army scientist secretly dosed with LSD by Sidney Gottlieb at a 1953 CIA retreat. Nine days later, he fell to his death from a tenth floor window at New York’s Statler Hotel. It was ruled a suicide. His family was not told for 22 years and has disputed it since.

Olson was a biological warfare scientist at Fort Detrick in Maryland who also worked for the CIA. By late 1953 he was having serious doubts about his work. At the Deep Creek Lake retreat that November, Gottlieb spiked the group’s drinks with LSD without warning, and Olson had a rough reaction. He told his wife he had made a terrible mistake and tried to resign days later. Colleagues flew him to New York with Robert Lashbrook, Gottlieb’s deputy, to see a doctor. In the early hours of November 28, 1953, he went through the closed, curtained window of their tenth floor room and died on the sidewalk below.

The CIA called it a suicide and did not tell Olson’s family about the secret LSD dosing. That only became public in 1975, through the Rockefeller Commission’s investigation. President Ford apologized, and Congress approved a 750,000 dollar settlement in 1976. Unsatisfied, the family had Olson’s body exhumed in 1994, and forensic scientist James Starrs found a skull injury he called more consistent with a blow than a fall. A 1996 homicide investigation followed and found insufficient evidence to bring charges, and no one has ever been prosecuted. The hosts land on their own theory, that Olson was killed rather than driven to jump, in part two of the investigation.
