C. V. Raman

Sir Chandrasekhara Venkata Raman, FRS (Tamil: சந்திரசேகர வெங்கடராமன்) (7 November 1888 – 21 November 1970) was an Indian physicist whose work was influential in the growth of science in the world. He was the recipient of the Nobel Prize for Physics in 1930 for the discovery that when light traverses a transparent material, some of the light that is deflected changes in wavelength. This phenomenon is now called Raman scattering and is the result of the Raman effect.

Venkata Raman was born at Thiruvanaikaval, near Tiruchirappalli, Madras Presidency to R. Chandrasekhara Iyer (b. 1866) and Parvati Ammal (Saptarshi Parvati).^[1] He was the second of their eight children. At an early age, Raman moved to the city of Vizag, Andhra Pradesh. Studied in St.Aloysius Anglo-Indian High School. His father was a lecturer in Mathematics and physics.
Raman entered Presidency College, Chennai in 1902. In 1904, he gained his B.Sc., winning the first place and the gold medal in physics. In 1907, he gained his M.Sc., obtaining the highest distinctions. He joined the Indian Finance Department as an Assistant Accountant General.

Career

In 1917, Raman resigned from his government service and took up the newly created Palit Professorship in Physics at the University of Calcutta. At the same time, he continued doing research at the Indian Association for the Cultivation of Science, Calcutta, where he became the Honorary Secretary. 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.

Personal life

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 with whom he had two sons, Chandrasekhar and Radhakrishnan.
C.V. Raman was the paternal uncle of Subrahmanyan Chandrasekhar, who later won the Nobel Prize in Physics (1983) for his discovery of the Chandrasekhar limit in 1931 and for his subsequent work on the nuclear reactions necessary for stellar evolution.

Honours and awards

Raman was honoured with a large number of honorary doctorates and memberships of scientific societies. He was elected a Fellow of the Royal Society early in his career (1924) and knighted in 1929. In 1930 he won the Nobel Prize in Physics. In 1941 he was awarded the Franklin Medal. In 1954 he was awarded the Bharat Ratna.^[2] He was also awarded the Lenin Peace Prize in 1957.
India celebrates National Science Day on 28 February of every year to commemorate the discovery of the Raman effect in 1928.
