LSD  My Problem Child

1. How LSD Originated

In the realm of scientific observation, luck

is granted only to those who are prepared.

Louis Pasteur



Time and again I hear or read that LSD was discovered by accident. This is only partly true. LSD came into being within a systematic research program, and the "accident" did not occur until much later: when LSD was already five years old, I happened to experience its unforeseeable effects in my own bodyor rather, in my own mind.

Looking back over my professional career to trace the influential events and decisions that eventually steered my work toward the synthesis of LSD, I realize that the most decisive step was my choice of employment upon completion of my chemistry studies. If that decision had been different, then this substance, which has become known the world over, might never have been created. In order to tell the story of the origin of LSD, then, I must also touch briefly on my career as a chemist, since the two developments are inextricably interrelated.

In the spring of 1929, on concluding my chemistry studies at the University of Zurich, I joined the Sandoz Company's pharmaceutical-chemical research laboratory in Basel, as a co-worker with Professor Arthur Stoll, founder and director of the pharmaceutical department. I chose this position because it afforded me the opportunity to work on natural products, whereas two other job offers from chemical firms in Basel had involved work in the field of synthetic chemistry.

Discovery of the Psychic Effects of LSD

Last Friday, April 16,1943, I was forced to interrupt my work in the laboratory in the middle of the afternoon and proceed home, being 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.
