India : Nobel Laureate Physicist

Birth :1888        Death : 1970

Dr.Chandra Shekhar Venkat Raman is one of the most distinguished scientists of the 20th century. His discovery known as the `Raman Effect’ made a very distinctive contribution to physics. For this discovery, he was awarded the Nobel Prize in Physics in 1930. He was the first Indian Scientist and also the first Asian to receive a Nobel Prize in Physics. This discovery of Raman is significant for one more reason. C.V. Raman studied and conducted his scientific researches living in India while there was the widely shared notion that no great scientific discovery could be made under the then existing scientific facilities in India. The scientific talent of Raman appeared at a very young age. His first Research paper, “The unsymmetrical diffraction bands due to a rectangular aperture” was published in London’s Philosophical Magazine when he was only 18. This research made Raman famous in world’s scientific circles. Later on, he made many important discoveries in light, sound and magnetism.

Dr. C.V. Raman was born on 7th November, 1888 in Tirchurappalli (Tamil Nadu). His father’s name was Chandra Shekhar Aiyer who had special interest in science and mathematics. His mother Parvati was a cultured lady. Raman was very intelligent since his early childhood. lie passed his matriculation when he was only 12. In 1904, when he was only 16, he passed his B.A. from the Presidency College, Madras, and was the only student to get a first class.

Then he appeared a competitive examination of the Finance Department (Accountant General) in Calcutta, but he was interested in scientific researches. Prof. Ashutosh Mukherjee, then Vice Chancellor of Calcutta University offered him a teaching post. Raman left his highly paid government job to become a Professor of science. In 1914, a science college was established in Calcutta and Raman was appointed its Principal. In 1921, he was awarded the degree of ‘Doctor of Science’ by the Calcutta University and in 1924, he was elected a Fellow of the Royal Society of London. In 1928, Raman was elected President of the Indian Science Congress and in 1929, the British government in India conferred on him the title of ‘Sir’. From 1933 to 1948, he was the Director of Indian  Institute of Science, Bangalore.

Meanwhile he continued to carry out different types of experiments and researches on the sun rays passing through water, transparent ice blocks and other media. For these experiments, Raman used a mercury arc and a spectograph. Raman obtained some new lines in the; spectrum on passing the sun rays through different substances. These lines were later called ‘Raman Lines’ and this discovery the ‘Raman Effect’. For this discovery he was awarded the Nobel Prize in Physics in help in the industrial development of the world. The government of India the same discovery. This discovery of Raman rendered the most valuable 1930. The Royal Society of London also awarded him `Hume Medal’ for also honoured him with the highest honour of the country ‘Bharat Ratna’ in 1954. Dr. C.V. Raman led a simple life.
