(Original Caption) Dr. Harry L. Williams (left) administers LSD 25 (lysergic acid diethylamide) to Dr. Carl Pfeiffer, chairman of Emory University’s Pharmacological Department, to produce effects similar to those experienced by schizophrenics. The new drug is being used in experiments to find out more about the inner feelings of the mentally ill and to discover whether a chemical disorder is responsible for mental illnesses. The microphone (foreground) was used to interview Dr. Pfeiffer during his journey through lunacy.
