Frank Rudolph Olson (July 17, 1910 – November 28, 1953) was an American bacteriologist, biological warfare scientist, and Central Intelligence Agency (CIA) employee who worked at Camp Detrick (now Fort Detrick) in Maryland.
At a meeting in rural Maryland, he was covertly dosed with LSD by his CIA supervisor and, nine days later, plunged to his death from the window of a 10th-story New York City hotel room.
The U.S.
government first described his death as a suicide, and then as misadventure, while others allege murder.
The Rockefeller Commission report on the CIA in 1975 acknowledged their having conducted drug studies.
