In the late 1950s and early 1960s, numerous men followed sex workers into the apartment at 225 Chestnut Street in San Francisco’s Telegraph Hill neighborhood. The johns were the unwitting subjects in a CIA experiment focused on how drugs and sex might be used to obtain secrets from foreign adversaries. Part of MKUltra, the agency’s broader and highly controversial mind control research program, Operation Midnight Climax began in 1953. The experiments involved luring men into a heavily surveilled bordello, dosing them with LSD, and filming their reactions to probing questions and subliminal messaging. The goal of Midnight Climax was to understand what roles, if any, sex and drugs could play in getting a target to reveal sensitive or classified information. To run the operation, Gottlieb hired George Hunter White, a federal narcotics agent, who got to work renovating the apartment. Microphones disguised as electrical wall outlets were hooked up to tape recorders, and a large two-way mirror allowed CIA agents to monitor, film, and photograph the encounters. Behind the mirror, a makeshift control room featured a portable toilet and a refrigerator full of adult beverages. Sex workers were given $100 for each man they lured to the bordello, and they would then dose their client with LSD-laced cocktails. Eventually these efforts revealed that a man became increasingly talkative if the sex worker asked him to stay awhile—even after the sexual transaction was complete.
Note: Midnight Climax was supervised by George Hunter White, who wrote this in a letter about the program: "Where else could a red-blooded American boy lie, kill, cheat, steal, rape, and pillage with the sanction and blessing of the All-Highest?" Former CIA officer and Iran-Contra whistleblower Bruce Hemmings put it best: "They do not give a damn about the law or the Constitution or the Congress or the Oversight committees except as something to be subverted and manipulated and lied to. If they can, they will blackmail you. Sex, drugs, deals, whatever it takes."
