Francis Crick reportedly discovered the double-helix model for DNA while high on LSD. But don't let that fool you, he was dropping acid with the full intention of having a great time; the discovery was just a nice bonus for the PhD. At Cambridge, Crick was THE guy to go to for a crazy party. According to author Matt Ridley, "a typical party, organised on the slightest pretext, would fill all four floors of the Golden Helix (the Crick household) with friends, music (Mike Oldfield's Tubular Bells was a favourite), punchbowls of drink and the scent of the odd joint in the air. Through all this, Crick, although married, flirted with breathtaking candour but 'in such a gallant and open way that few were offended and most were charmed.'" Crick campaigned for the legalization of drugs, and probably egged the stuffy James Watson's house on several occasions.
