Bicycle Day is the anniversary of the first recorded LSD trip by Albert Hofmann, April 19, 1943: While researching lysergic acid derivatives, Hofmann first synthesized LSD on November 16, 1938. The main intention of the synthesis was to obtain a respiratory and circulatory stimulant. On April 19, 1943, Hofmann ingested 0.25 milligrams (250 micrograms) of the substance. Less than one hour later, Hofmann experienced sudden and intense changes in perception. He asked his laboratory assistant to escort him home. As was customary in Basel, they made the journey by bicycle. The events of the first LSD trip, now known as “Bicycle Day”, after the bicycle ride home, proved to Hofmann that he had indeed made a significant discovery: a psychoactive substance with extraordinary potency, capable of causing significant shifts of consciousness in incredibly low doses
