1938 – Albert Hofmann accidentally discovers LSD

Albert Hoffman was a chemist working for Sandoz Laboratories in Basel when he discovered LSD-25. He had been researching lysergic acid derivatives, hoping to find a stimulant for the respiratory and circulatory systems with fewer birth defects than existing drugs. On the day, he was disappointed in the substance he had created, and moved on to other work.

It would be five years until he returned to it and, accidentally absorbing some of it via his fingertips, had the world’s first acid trip.
