The Nobel Prize in Physics 1930 was awarded to Sir Venkata Raman. The citation read "for his work on the scattering of light and for the discovery of the effect named after him". Here is a link where you can find the presentation speech delivered by Professor H. Pleijel, Chairman of the Nobel Committee for Physics of the Royal Swedish Academy of Sciences, on December 10, 1930 before felicitating Sir Raman.
Also, a brief history around Sir Raman's discovery clarifies many questions and doubts. So, here is an article which briefly describes the scientific research activities which was going on around that period, across the globe and corresponding events that could probably have lead to what we call "Raman Effect".
