Albert Hofmann
Swiss chemist, 1906-2008
"Albert Hofmann was a Swiss scientist known best for being the first known person to synthesize, ingest, and learn of the psychedelic effects of lysergic acid diethylamide (LSD). Hofmann was also the first person to isolate, synthesize, and name the principal psychedelic mushroom compounds psilocybin and psilocin. He authored more than 100 scientific articles and numerous books, including ""LSD: Mein Sorgenkind"" (""LSD: My Problem Child""). His main interest was the chemistry of plants and animals, and he conducted important research on the chemical structure of the common animal substance chitin, for which he received his doctorate with distinction in 1929."
