Srinivasa Ramanujan Iyengar (best know as S. Ramanujan) is hailed as an all-time great mathematician, like Euler, Gauss or Jacobi, for his natural genius. Despite his lack of formal education, hardship, poverty and a short life-span, he rose to such a scientific standing and reputation that no Indian has enjoyed before. Probably Ramanujan’s life has no parallel in the history of human thought. He was an autodidact mathematical genius not only of the twentieth century but for all time to come.
