Later, he started doing experiments at the Indian Association for the Cultivation of Science (IACS). In 1917, Raman resigned from his government service and took up the newly created post of Palit Professorship in Physics at the University of Calcutta. At the same time, he continued with his research at IACS. He presided over the 16th session of the Indian Science Congress in 1929.
In addition to his Nobel prize winning work on the scattering of light, Raman worked on the acoustics of musical instruments. In 1934, he became the director of the newly established Indian Institute of Science in Bangalore and in 1947 was appointed as the first National Professor by the new government of free India.
He was awarded the Bharat Ratna in 1954 and received the Lenin Peace Prize in 1957. The government has honoured Sir CV Raman by declaring 28th February every year as National Science Day to commemorate Raman's discovery in 1928. Last Updated on : January 30, 2014
