NAME: Chandrasekhara Venkata Raman

BORN IN: 7th November, 1888

An Indian Physicist, whose work influenced the growth of science in the world. He was awarded Nobel Prize in Physics in 1930 for his discovery that when light traverse a transparent material, some of the deflected light changes its wavelength. This phenomenon is known as Raman scattering and the result of Raman Effect.

Education: Venkata Raman was born at Thiruvanaikaval, near Tiruchirappalli. He was the second child of his parents. At an early age he moved to Vizag. He studied in St.Aloysius Anglo-Indian High School. His father was a lecturer in Mathematics and physics, so he brought up in an academic ambience. He entered into Presidency College, Chennai in 1902. In 1904 he received Bachelor of Science degree, stood first and the received gold medal in physics. In 1907, he mastered in science with highest distinction. He then joined to Indian Finance Department as an Assistant Accountant General.

Career: In 1917, Raman resigned from his government service and joined in University of Calcutta as Palit Professorship.

He referred this period as the golden era of his career. There he had many students around him at the IACS and the University of Calcutta. C. V. Raman on laboratory

On February 28, 1928, through his experiments on the scattering of light, he discovered the Raman scattering. It gave further proof of the quantum theory of Light. In 1929 he was president of Indian Science Congress Association. He was conferred Knighthood. Several medals and honorary doctorates were given by several universities. In 1930 he received Nobel Prize. He was the first Asian to receive Nobel in science.

Later in 1932, he and Bhagavantam discovered the quantum photon spin, which confirmed the quantum nature of light. He also worked on acoustics of musical sound. He and his student gave correct explanation of acousto-optic effect i.e. light scattering by sound waves.

In 1934, he became the director of Indian Institute of Science, Bangalore. He continued two years as professor of physics. In 1943, he along with Dr. Krishnamurthy started a company named, Travancore Chemical and Manufacturing Co. Ltd. In 1947, after independence he was appointed as first National Professor.

Awards:
1. Honoured several honorary doctorates and memberships of scientific societies.
2. Fellow of the Royal Society in 1924.
