I think your off by a couple of years
Albert Hofmann, a chemist working for Sandoz Pharmaceutical, synthesized1 LSD for the first time in 1938, in Basel, Switzerland, while looking for a blood stimulant. However, its hallucinogenic effects were unknown until 1943 when Hofmann accidentally consumed some LSD. It was later found that an oral dose of as little as 25 micrograms (equal in weight to a few grains of salt) is capable of producing vivid hallucinations.
