Albert Hofmann was a Swiss chemist known for being the first to synthesize, ingest, and learn of the psychedelic effects of lysergic acid diethylamide (LSD). Hofmann's team also isolated, named and synthesized the principal psychedelic mushroom compounds psilocybin and psilocin. He authored more than 100 scientific articles and numerous books, including LSD: Mein Sorgenkind. In 2007, he shared first place with Tim Berners-Lee on a list of the 100 greatest living geniuses published by The Daily Telegraph newspaper.

Psilocybin mushrooms, commonly known as magic mushrooms or shrooms, are a polyphyletic informal group of fungi that contain psilocybin, which turns into psilocin upon ingestion. Biological genera containing psilocybin mushrooms include Psilocybe, Panaeolus, Inocybe, Pluteus, Gymnopilus, and Pholiotina.
