Raffi Khatchadourian, Operation Delirium. The New Yorker, 17 December 2012. “Military doctors who helped conduct the [psychochemical] experiments [during the 1950s and ’60s] have long since moved on, or passed away, and the soldiers who served as their test subjects—in all, nearly five thousand of them—are scattered throughout the country, if they are still alive. Within the Army, and in the world of medical research, the secret clinical trials are a faint memory. But for some of the surviving test subjects, and for the doctors who tested them, what happened at Edgewood remains deeply unresolved. Were the human experiments there a Dachau-like horror, or were they sound and necessary science?” Companion piece to Operation Delirium: High Anxiety: LSD in the Cold War by Raffi Khatchadourian, The New Yorker, 16 December 2012. “For decades, the U.S. Army conducted secret clinical experiments with psychochemicals at Edgewood Arsenal. In the nineteen-sixties, Army Intelligence expanded the arsenal’s work on LSD, testing the drug as an enhanced-interrogation [torture] technique in Europe and Asia. This companion piece to “Operation Delirium”…documents the people who were involved and what they did.” Primary Sources : Operation Delirium, The New Yorker, 26 December 2012.
