Gerald D. Klee, a retired psychiatrist and LSD expert who participated in experiments with the hallucinogenic drug on volunteer servicemen at U.S. military installations in the 1950s, has died. He was 86.
Klee died Sunday of complications after surgery at the University of Maryland St. Joseph Medical Center in Towson, Md., his family said.
In 1975, Klee made headlines when he confirmed reports that the University of Maryland School of Medicine’s Psychiatric Institute had been involved in secret research between 1956 and 1959, when hundreds of soldiers were given LSD, or lysergic acid diethylamide.
He said that in addition to LSD, the Army was experimenting with other hallucinogens as part of its chemical weapons research program.
