Lysergic acid diethylamide (LSD) was first synthesised by Swiss chemist Albert Hofmann in 1938 at Sandoz Laboratories in Basel, Switzerland.
LSD (also known colloquially as acid) and other psychedelics became synonymous with the 1960s counterculture movement due to their perceived ability to expand consciousness. The drugs’ influence on literature, art, film and, in particular, music cannot be overstated.
Harvard University clinical psychologist Dr. Timothy Leary was a great advocate of LSD. In 1966, Leary urged everyone to “Turn on, tune in, drop out.”
Footnote: ‘The Doors of Perception’ was written by English author, Aldous Huxley. The book recalls his psychedelic experiences under the influence of mescaline in 1953. No prizes for guessing which American rock band took their name from the book’s title.
