"Francis Crick, the Nobel Prize-winning father of modern genetics, was under the influence of LSD when he first deduced thedouble-helix structure of DNA nearly 50 years ago.

Crick told a fellow scientist that he often used small doses of LSD then an experimental drug used in psychotherapy to boost his powers of thought. He said it was LSD, not the Eagle's warm beer, that helped him to unravel the structure of DNA, the discovery that won him the Nobel Prize."
