Srinivasa Iyengar Ramanujan FRS (pronunciation: Listeni/ˈʃrniˌvɑːsə ˈrɑːmɑːˌnʊən/; 22 December 1887 – 26 April 1920) was an Indian mathematician and autodidact who lived during the British Raj. Though he had almost no formal training in pure mathematics, he made substantial contributions to mathematical analysis, number theory, infinite series, and continued fractions. Ramanujan initially developed his own mathematical research in isolation; it was quickly recognized by Indian mathematicians. When his skills became obvious and known to the wider mathematical community, centred in Europe at the time, he began a partnership with the English mathematician G. H. Hardy. The Cambridge professor realized that Srinivasa Ramanujan had produced new theorems in addition to rediscovering previously known ones.
