Srinivasa Ramanujam Iyengar (22 December 1887 – 26 April 1920) was an Indian self-educated mathematician who had no formal training in mathematics. During his time when India was a British colony and when Indians where deprived of even basics under British rule, Srinivasan Ramanujam Iyenger shined as true genius. Even though he lived a short life of 32 years, he made substantial contributions to mathematical analysis, number theory, infinite series, and continued fractions. Initially in isolation, Ramanujam developed his own mathematical research, which was very soon recognized by other Indian mathematicians. As soon as the mathematical community centered in Europe sensed his skills, G.H. Hardy an English Mathematician partnered with him. The Cambridge professor realized that Ramanujan had produced new theorems in addition to rediscovering previously known ones. Ramanujam independently compiled nearly 3,900 results of identities and equations.
1.He was born in Erode, Tamil Nadu. His father worked as clerk with a cloth merchant and his mother primarily a homemaker use to sing at local temple.
2.His family had moved to Kumbakonam after his birth and the house where he lived is Srinivasa Ramanujam International Monument now.
3.His wife Janaki Ammal was 9 years old when they got married in 1909.
4.In spite of no formal training in mathematics he was considered as one of the greatest mathematician of his time.
6.He at the age of 31 in 1918 was inducted as a Fellow of the Royal Society, considered as Fellowship of some of the world’s most eminent scientist. He was the youngest to be inducted in the history of the society and the second Indian.
7.His infinite series for pi was his most celebrated one.
9.He quoted “An equation for me has no meaning, unless it represent a thought of god.”
10.Every year, December 22, his birth anniversary is celebrated as the National Mathematics Day.
