The first person to ever trip on acid wasn’t even aware of what it could do. Albert Hoffman was a Swiss chemist working to create a stimulant for the respiratory and circulatory systems, and he synthesized a drug called lysergic acid diethylamide. On April 19, 1943, Hoffman ingested 0.25 milligrams of what we now call LSD. With another mixture, this amount could have been irrelevant. But the LSD changed Hoffman’s life.
