Chanderasekhera Venkata Raman was born on 07 November 1888 Thiruvanailkol, Trichinapalli, Tamilnadu.


He was an Indian Physicist,  which get Nobel Prize for physics in 1930. He get prize for the invention of light  scattering.   He  invented that when light transverse a transparent material,  some of deflected light changes its wavelength .This is known as Raman Scattering as result of Raman effect.


In 1954 Raman get  honoured  by greatest civillian award Bharat Ratna.In the age of early 11 he passed matriculation and at the age of 13 he got the scholarship in 12th class.


In 1902 , he joined the presidency colege Madras, where his father was lecturer of mathematics and physics.He got gold medal in B.A.  in Physics and top the university in Master of Science.


Raman used to refer to this period as the golden era of his career. Many students gathered around him at the IACS and the University of Calcutta.


Raman Spectroacopy came to be based on this phenomenon, and Ernest Rutherford referred to it in his presidential address to the Royal Society in 1929. Raman was president of the 16th session of the Indian Science Congress in 1929. He was conferred a Knighthood, and medals and honorary doctorates by various universities.


He did eventually win the 1930 Nobel Prize in Physics "for his work on the scattering of light and for the discovery of the Raman effect"


Raman and Suri Bhagvantam discovered the quantum photon spin in 1932, which further confirmed the quantum nature of light.


Raman retired from the Indian Institute of Science in 1948 and established the Raman Research Institute in Bangalore, Karnataka, a year later. He served as its director and remained active there until his death in 1970, in Bangalore, at the age of 82.


He was married on 6 May 1907 to Lokasundari Ammal (1892–1980).They had two sons, Chandrasekhar and radio-astronomer Radhakrishnan.


During a voyage to Europe in 1921, Raman noticed the blue colour of glaciers and the Mediterranean sea. He was motivated to discover the reason for the blue colour. Raman carried out experiments regarding the scattering of light by water and transparent blocks of ice which explained the phenomenon.


The Raman Research Institute founded by Raman after his tenure at IISc, curates a collection of Raman's research papers, and articles on the web.


At the end of October 1970, Raman collapsed in his laboratory, the valves of his heart had given way. He was moved to the hospital and the doctors gave him four days to live. He survived and after a few days refused to stay in the hospital as he preferred to die in the gardens of his Institute surrounded by his followers.


Two days before Raman died, he told one of his former students, "Do not allow the journals of the Academy to die, for they are the sensitive indicators of the quality of science being done in the country and whether science is taking root in it or not." That same evening, Raman met with the Board of Management of his Institute and discussed (from his bed) with them any proceedings with regards to the Institute's management. Raman died from natural causes early next morning on 21 November 1970.
