Albert Hofmann, a Swiss scientist, takes the first intentional LSD "trip." Hofmann had accidentally absorbed some of the chemical three days ago and is intentionally taking it today to confirm his suspicions about it.
Albert Hofmann described the experience:
"... affected by a remarkable restlessness, combined with a slight dizziness. At home I lay down and sank into a not unpleasant intoxicated-like condition, characterized by an extremely stimulated imagination.
In a dreamlike state, with eyes closed (I found the daylight to be unpleasantly glaring), I perceived an uninterrupted stream of fantastic pictures, extraordinary shapes with intense, kaleidoscopic play of colors. After some two hours this condition faded away"
