As I understand it after winning two (un-shared) Nobel prizes Linus Pauling began work which eventually had him recommending large amounts of vitamin C to all and sundry.
When another scientist was unable to repeat the results a scandal began. Linus Pauling and/or his people made savage professional attacks on the poor researcher who just wanted to know how to get the same results in an experiment. Once the smoke settled it became clear that Pauling's conclusions were wrong after all and he should be ashamed of himself for treating another scientist so shabbily. Much was made about how far the mighty have fallen, a lesson to us all etc.
What I never hear about was What was Pauling's original claim in this regard and how did he reach it? By what error or series of errors did he make such mistakes. I can imagine based on the severity of his defense he might have been long passed the rational portion of his life. But what was the primary claim, and for that matter, why do we seem to still act as if it were all true, that vitamin C is the answer; scurvy notwithstanding.
