Ramanujan, Srinivasa (shrēˌnĭväˈsə rämäˈnŏjən) [key], 1889–1920, Indian mathematician. He was a self-taught genius in pure mathematics who made original contributions to function theory, power series, and number theory with the training gained from a single textbook. He was invited to Cambridge by G. H. Hardy, with whom he collaborated, and continued there his work in number theory. He died of tuberculosis.
