The Swiss chemist, Albert Hofmann, discovered lysergic acid diethylamide-25 in 1938 while studying the medicinal uses of a fungus found on wheat and other grains at the Sandoz pharmaceuticals firm in Basel. He became the first human guinea pig of the drug when a tiny amount of the substance seeped on to his finger during a repeat of the laboratory experiment on April 16, 1943.
"I had to leave work for home because I was suddenly hit by a sudden feeling of unease and mild dizziness," he subsequently wrote in a memo to company bosses.
"Everything I saw was distorted as in a warped mirror," he said, describing his bicycle ride home. "I had the impression I was rooted to the spot. But my assistant told me we were actually going very fast."
