The psychedelic drug (or entheogen) lysergic acid diethylamide (LSD) was first synthesized on November 16, 1938, by the Swiss chemist Albert Hofmann in the Sandoz laboratories in Basel, Switzerland.[1] It was not until five years later on April 19, 1943, that the psychedelic properties were found.[2] 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.[1]
