Srinivasa Ramanujan Biography :  Srinivasa Ramanujan was born on (December 22, 1887, in Erode town, Tamil Nadu India). And he was an Indian greatest mathematician given contributions to number theory, functions, and infinite series.
National Mathematics Day is observed on 22 December annually to commemorate the birth anniversary of the great Indian Mathematician Srinivasa Ramanujan.
In 2012, Dr Manmohan Singh, then Prime Minister, declared December 22 as National Mathematics Day. December 22nd was the 134th birth anniversary of Srinivasa Ramanujan. Let us have a look at his childhood, early life, education, contributions and major works, awards and achievements, etc.

Srinivasa Ramanujan: Childhood, and Early Life
He was born on 22nd December 1887 into a Tamil Brahmin Iyengar family in Erode, Madras Presidency (now Tamil Nadu, India) at his maternal grandparent's residence. His father was K. Srinivasa Iyengar, an accounting clerk for a clothing merchant, and his mother was Komalatammal, a housewife and sang at a local temple.
The family was of high caste and was very poor. Srinivasa Ramanujan's parents moved around a lot, and so he attended a variety of different elementary schools.
In November 1897, he passed his primary examinations in English, Tamil, geography, and arithmetic, and gained vast scores in the district. He entered Town Higher Secondary School in the same year and encountered formal mathematics for the first time.
Srinivasa Ramanujan: Discovery as a Mathematician of Genius
At the age of 11, he had taken the mathematics knowledge of two college students who were lodgers at his home. Later, he borrowed a book written by SL Loney on advanced trigonometry. By the age of 13, he had mastered it and discovered theorems on his own.
At 14 years of age, he received merit certificates and academic awards that continued all through his school career. Also, he completed an exam in mathematics in half of the allotted time and showed familiarity with geometry and infinite series.
In 1902, he showed how to solve cubic equations. He also developed his own methods.
At the age of 15, he obtained a copy of George Shoobridge Carr’s Synopsis of Elementary Results in Pure and Applied Mathematics, 2 vol. It consists of thousands of theorems. He studied the contents of the book in detail and went beyond and developed his own theorems and ideas. This book acts as a key element in awakening his genius. It is said that he independently developed and investigated the Bernoulli numbers and calculated the Euler-Mascheroni constant up to 15 decimal places.
He secured a scholarship in 1903 to the University of Madras but lost it in the following years due to the negligence of all other studies in pursuit of mathematics. He met with the founder of the Indian Mathematical Society, V Ramaswamy Aiyer in 1910 and began to gain recognition in Madras mathematical circles and leading to his inclusion as a researcher at the University of Madras.
Srinivasa Ramanujan: Marriage and Career in Mathematics
In July 1909, he married Janakiammal. He became ill and went for surgery around 1910. After his successful surgery, he searched for a job. He also tutored students at Presidency College in Madras who were preparing for their Fellow of Arts exam. In 1910, he met V. Ramaswamy Aiyer, who founded the Indian Mathematical Society. He convinced him and luck favoured. And as a result, with the help of Aiyer, his work had been published in the Journal of the Indian Mathematical Society.
He got the job in 1912 as an accounting clerk with the Madras Port Trust and his financial condition improved.
His intelligence and genius slowly gained recognition and he began a correspondence in 1913 with the British mathematician Godfrey H. Hardy that led to a special scholarship from the University of Madras and a grant from Trinity College, Cambridge.
Srinivasa Ramanujan: Life in England
He travelled to England in 1914, where Hardy tutored him. He collaborated with him on some research work.
