Calyampudi Radhakrishna Rao was born at Hadagali in Karnataka. In 1945 he put forward the "theory of estimation" in statistics. His formulae and therorems, for instance the "Cramer-Rao inequality", "The Fisher-Rao theorem" and "Rao-Black Wellistaion" are now part of any standard textbook of statistics. For his significant contributions, Rao received the S. S. Bhatnagar Award, the Meghnad Saha Medal and the Guy medal.
