Sir Chandrasekhara Venkata Raman
(7 November 1888 – 21 November 1970) was an Indian physicist, born in the former Madras Province, whose ground breaking work in the field of light scattering earned him the 1930 Nobel Prize for Physics. He discovered that, when light traverses a transparent material, some of the deflected light changes in wavelength. This phenomenon is now called Raman scattering and is the result of the Raman effect. In 1954, he was honoured with the highest civilian award in India, the Bharat Ratna.
C.V.Raman was born to a Tamil Brahmin Iyer family in Thiruvanaikaval, Trichinopoly, (present-day Tiruchirapalli), Madras Presidency Tamil Nadu, in British India to Parvati Amma.
Raman's father initially taught in a school in Thiruvanaikaval, became a lecturer of mathematics and physics in Mrs. A.V. Narasimha Rao College, Vishakapatnam (then Vishakapatnam) in the Indian state of Andhra Pradesh, and later joined Presidency College in Madras (now Chennai).
