Krishnan was not nominated for the Nobel Prize even though he was the main researcher in the discovery of Raman effect. It was he alone who first noted the new scattering. Krishnan co-authored all the scientific papers on the discovery in 1928 except two. He alone wrote all the follow-up studies. Krishnan himself never claimed himself worthy of the prize. But Raman admitted later that Krishnan was the co-discoverer. He however remained openly antagonistic towards Krishnan, which the latter described as "the greatest tragedy of my life." After Krishnans death, Raman said to a correspondent from The Times of India, "Krishnan was the greatest charlatan I have known, and all his life he masqueraded in the cloak of another mans discovery."
