<P> Srinivasa Ramanujan FRS ( / ˈʃriːniˌvɑːsə rɑːˈmɑːnʊdʒən / ; listen ( help info ) ; 22 December 1887 -- 26 April 1920 ) was an Indian mathematician who lived during the British Rule in India . Though he had almost no formal training in pure mathematics , he made substantial contributions to mathematical analysis , number theory , infinite series , and continued fractions , including solutions to mathematical problems considered to be unsolvable . Ramanujan initially developed his own mathematical research in isolation ; it was quickly recognized by Indian mathematicians . Seeking mathematicians who could better understand his work , in 1913 he began a postal partnership with the English mathematician G.H. Hardy at the University of Cambridge , England . Recognizing the extraordinary work sent to him as samples , Hardy arranged travel for Ramanujan to Cambridge . In his notes , Ramanujan had produced groundbreaking new theorems , including some that Hardy stated had `` defeated ( him and his colleagues ) completely '' , in addition to rediscovering recently proven but highly advanced results . </P>
