Although carefully balanced, your obituary of Albert Hoffmann still fails to give him his due as a scientist (May 10, 2008). He died a disappointed man because he was convinced that lysergic acid diethylamide or LSD, which he synthesized early in his career, had an enormous liberating potential left unexplored because of careless abuse. As witnessed by his LSD: My Problem Child (New York: McGraw-Hill, 1980), he considered it a scientific feat on a par with nuclear fission. Carefully administered, it could help millions discover and master a fabulous spiritual realm that is difficult to reach by other means. Besides, LSD is neither toxic nor addictive, and it is not known to have caused a single death by overdose. All this went awry because of incompetence and irresponsibility of early adepts, such as Timothy Leary. Ever a good scientist, Hoffmann made every effort to impart this message till the bitter end. Your obituary could have at least hinted at his unfulfilled mission.
