History of LSD

The psychedelic drug lysergic acid diethylamide (LSD) was first synthesized on November 16, 1938, by the Swiss chemist Albert Hofmann in the Sandoz laboratories in Basel, Switzerland. It was not until five years later on April 19, 1943, that the psychedelic properties were found. Today, the discovery of LSD is celebrated worldwide during the annual Bicycle Day holiday, serving also as the day celebrating the psychedelic revolution in general.
