It would be another 24 years until Jimi Hendrix would release “Are You Experienced,” but Albert Hofmann became the first person in history who could conceivably answer in the affirmative to that when he discovered LSD’s hallucinogenic effects after accidentally dosing himself on April 16, 1943.
The Swiss chemist stumbled across the drug while testing the medicinal value of lysergic acid compounds and, after consuming it accidentally and experiencing “an intoxicated-like condition characterized by an extremely stimulated imagination,” Hofmann took it again three days later.
Now known as “Bicycle Day” because of the mode of transportation Hofmann used to get home, April 19, 1943, was the date of the first intentional trip – but the first overall trip in history marks its 75th anniversary today.
To help mark 75 years of “fantastic pictures” and “extraordinary shapes with intense, kaleidoscopic play of color,” we’ve tabbed up a list of 75 times lysergic acid diethylamide worked its magic or impacted history, for better or worse.
