Nobel Prize Winner Sir Chandrashekhara Venkata Raman

Sir Chandrashekhara Venkata Raman was born on 7 November 1888 and died on 21 November 1970. He was an Indian physicist born in the former Madras Province in India. He carried out ground-breaking work in the field of light scattering, which earned him the 1930 Nobel Prize for Physics, and was the first person in Asia to obtain the said award for achievements in science.

C.V. Raman discovered the Raman effect, which occurs when light that shines through a material is scattered and its wavelength changes from that of the original incident light because of its interactions with the molecules in the material.

Raman was knighted in 1929, and in 1933 he moved to the Indian Institute of Science, at Bangalore, as head of the department of physics. In 1947 he was named director of the Raman Research Institute there and in 1961 became a member of the Pontifical Academy of Science. 

He contributed to the building up of nearly every Indian research institution in his time, founded the Indian Journal of Physics and the Indian Academy of Sciences, and trained hundreds of students who found important posts in universities and government in India and Myanmar (Burma).

He discovered that when light traverses a transparent material, some of the deflected light changes wavelength and amplitude. This phenomenon, subsequently known as Raman scattering, results from the Raman effect. In the year 1954, the Indian government honored him with India’s highest civilian award, the Bharat Ratna.
