Sir Srinivasa Ramanujam

(1887 – 1920):

Great Indian Mathematician, whose interest from academics at Trinity, College, Cambridge, led him to collaborate there and postulate and prove well over 3,542 theorems

**Ramanujan was among greatest mathematical geniuses. He made substantial contributions to the analytical theory of numbers and worked on elliptic functions, continued fractions, and infinite series.**

**Born in poor family in pre-independent India, Ramanujan discovers the power of number theory. ****He gave many theorems & proofs, some of them are still problem to present mathematicians. **

**Srīnivāsa Aiyangār Rāmānujan ****FRS****, known as Srinivasa Iyengar Ramanujan ****(22 December 1887 – 26 April 1920) was an Indian ****mathematician**** who, with almost no formal training in ****pure mathematics****, made substantial contributions to ****mathematical analysis****, ****number theory****, ****infinite series**** and ****continued fractions****.**

**Born and raised in ****Erode****, ****Tamil Nadu****, ****India****, Ramanujan first encountered formal mathematics at age 10. He demonstrated a natural ability, and was given books on advanced ****trigonometry**** written by ****S L Loney****. He had mastered them by age 12, and even discovered ****theorems**** of his own. He demonstrated unusual mathematical skills at school, winning accolades and awards. By 17, Ramanujan conducted his own mathematical research on ****Bernoulli numbers**** and the ****Euler–Mascheroni constant****. **

**He received a scholarship to study at Government College in ****Kumbakonam****, but lost it when he failed his non-mathematical coursework. He joined another college to pursue independent mathematical research, working as a clerk in the Accountant-General's office at the Madras Port Trust Office to support himself. **

**In 1912–1913, he sent samples of his theorems to three academics at the ****University of Cambridge****. Only ****G. H. Hardy**** recognized the brilliance of his work, subsequently inviting Ramanujan to visit and work with him at Cambridge. He became a ****Fellow of the Royal Society**** and a Fellow of ****Trinity College, Cambridge****, dying of illness, malnutrition and possibly liver infection in 1920 at the age of 32.**
