Sir Chandrasekhara Venkata Raman[2] (7 November 1888 – 21 November 1970) was an Indian physicist born in the former Madras Province in India presently called as Tamil Nadu, who carried out ground-breaking work in the field of light scattering, which 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, subsequently known as Raman scattering, results from the Raman effect.[3] In 1954, India honoured him with its highest civilian award, the Bharat Ratna.[4][5]

Raman's father initially taught in a school in Thiruvanaikaval, became a lecturer of mathematics and physics in Mrs. A.V. Narasimha Rao College, Visakhapatnam (then Vishakapatnam) in the Indian state of Andhra Pradesh, and later joined Presidency College in Madras (now Chennai).[
