Operation Midnight Climax was an operation initially established by Sidney Gottlieb and placed under the direction of Federal Narcotics Bureau in Boston, Massachusetts with the officer George Hunter White under the pseudonym of Morgan Hall for the CIA as a sub-project of Project MKULTRA, the CIA mind-control research program that began in the 1950s. Before the programs were shut down, hundreds of scientists would work on them.
The project consisted of a web of CIA-run safehouses in San Francisco, Marin, and New York City. It was established in order to study the effects of LSD on unconsenting individuals. Prostitutes on the CIA payroll were instructed to lure clients back to the safehouses, where they were surreptitiously plied with a wide range of substances, including LSD, and monitored behind one-way glass. Every one of these acts was blatantly illegal and several significant operational techniques were developed in this theater, including extensive research into sexual blackmail, surveillance technology, and the possible use of mind-altering drugs in field operations.
The Operation Midnight Climax soon expanded and CIA operatives began dosing people in restaurants, bars and beaches.
