http://www.cnn.com/2008/US/04/29/hofmann.obit.ap/index.html Albert Hofmann, father of the mind-altering drug LSD whose medical discovery grew into a notorious "problem child," died Tuesday. He was 102 "I produced the substance as a medicine. ... It's not my fault if people abused it," he said. The Swiss chemist 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 onto his finger during a repeat of the laboratory experiment 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 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." Three days later, Hofmann experimented with a larger dose. The result was a horror trip.
