Mathematician, born in Erode, India. The child of poor parents, he taught himself from an elementary English textbook. Although he attended college, he did not graduate. While working as a clerk, he was persuaded to send over 100 theorems that he had discovered to Godfrey Hardy at Cambridge, including results on elliptic integrals, partitions, and analytic number theory. Hardy was so impressed that he arranged for him to come to Cambridge in 1914. He was the first Indian to be elected a Fellow of the Royal Society.
