The Accidental Creation of LSD (The Origin of Bicycle Day)

Swiss chemist Albert Hofmann deliberately took LSD for the first time. Less than an hour later, he experienced changes in perception. He asked his laboratory assistant to escort him home and, as a use of motor vehicles was prohibited because of wartime restrictions, they had to make the journey on a bicycle. Therefore, LSD users call April 19 the Bicycle day.
