He is often remembered as the genius who won the 1930 Nobel Prize for Physics, working with simple equipment barely worth Rs. 300.
Chandrasekhara Venkata Raman was one of the greatest experimental physicists of the century and the first Asian scientist to win the Nobel Prize. His spirit of inquiry and devotion to science laid the foundations for scientific research in India, for not only did he win honour as a scientist but also inspired several generations of students.
Even as a student he read far beyond his classroom level and when doubts arose, set down questions like 'How?' 'Why?' and 'Is this true?' in the margin of textbooks.
Raman frequently referred to this period at Calcutta University as the golden era in his career. Absorbed in experiments, it was not unusual for him to forget food and sometimes, working late through the night, he would sleep on one of the laboratory tables.
Raman was a great lover of music and used to say, I should live long, because I have not heard all the music I want to hear. Raman loved colour, beauty, form, and rhythm in nature.
The Raman effect, as it is more popularly known, had its origin in the wonderful blue colour of the Mediterranean Sea. In 1921, on his way to Oxford to attend the Universities’ Conference by ship, Raman was struck by the deep blue opalescence of the Mediterranean water. On board the ship itself, he conducted some experiments using a nicol prism. Soon after returning to Calcutta, he carried out more experiments at his IACS Laboratory, with waters collected from different seas. He came to the definite conclusion that it was the scattering of light molecules by the oceanic waters that made them look blue. For the next seven years, Raman and his students carried out several experiments and established the various laws of molecular scattering of light in diverse media and 56 original research papers were published from Raman’s laboratory. He continued his experiments on various materials.

On February 28,1928, Raman had announced the discovery to the press and the public. The Raman Effect was perceived as one of the greatest discoveries of the third decade of the twentieth century.
