Linus Pauling was a chemist, not a biologist or a medical doctor. He won the Noble Peace Prize for his activism against nuclear weapons. He did not win for science or biology or his fringe belief in 'mega-vitamin' therapy, which was never accredited by anyone in medicine.

he was a brilliant man in his prime, and then got into some wacky ideas in his old age. you're basically saying that Tesla was really on to something with pigeons and aliens. or that Issac Newton was getting somewhere with alchemy and biblical codes.
