Srinivasa Ramanujan(1887-1920)
  • He was born on 22, December 1887 in a village of Tamilnadu (Erode).

  • He got his taste in mathematics during his studies in Town high school of Kumbakonam. From the childhood, he showed his interest in mathematics. His life took a turn when he read the book “A Synopsis of Elementary Results in Pure and Applied Mathematics” which he had borrowed from his friend. He studied all the 5000 theorems contained in the book thoroughly.
  • He took admission in the Government Arts College, Kumbakonam.  He used to receive scholarship for his studies. But he was so much involved in mathematics that he neglected all the other subjects and lost his scholarship. Later he enrolled in the Pachaiyappa’s College. He faced similar problem there and left the college without any degree.
  • He faced many problems in his professional life and spent many days in poverty. In the beginning, he published his work in the Journal the Indian mathematical society. He also sent his work to many English mathematicians. But few showed interest. Among them he worked with professor G.H. Hardy and J.E. Littlewood. They invited him to the Cambridge. Initially he was reluctant but at last he left Madras in 1914. He spent about five years in England. There he published many papers with G.H. Hardy and J.E. Littlewood.
