Field
Scientists & Thinkers
“Nature reveals her secrets to the patient — the laboratory is the temple of the physicist.”
— The spirit of K.S. Krishnan
The Story
Born in 1898 in Watrap, Krishnan studied physics at Madras and joined the Indian Association for the Cultivation of Science in Calcutta, where he worked beside C.V. Raman. It was in this collaboration that the famous experiment was performed that revealed the Raman Effect — the scattering of light that earned Raman the Nobel Prize — and Krishnan was the co-discoverer of the phenomenon.
He went on to do pioneering work in crystal physics and magnetism, establishing himself as one of the founders of solid-state physics in Bhārat. He built the physics department at Allahabad University and then served as the director of the National Physical Laboratory, building it into a great centre of research.
He died in 1961, honoured as one of the architects of modern physics research in Bhārat. His precision, his integrity, and his devotion to research made him the model of the scientist, and his name stands beside Raman's in the history of the discovery that made Bhārat's science world-famous.
