Srinivasa Ramanujan, an Indian mathematician.

Srinivasa Ramanujan (22 December 1887-26 April 1920) was an Indian mathematician. Who contributed to the analytical theory of numbers and worked on elliptic functions, continued fractions, and infinite series.


Srinivasa Ramanujan was born on 22 December 1887, in Tamil Nadu, India. His father K. Srinivasa Iyengar worked as an accountant for a clothing company. His mother Komalatammal was a singer at a local temple. He studied at the Kumbakonam Town High School, and he was a top student in his district.

He began working on geometry and arithmetic sums on his own in 1900. He had his own method of solving quadratic equations.

In 1903, his main source of inspiration and expertise came from a book written by George Shoobridge Carr. It presented a ton of mathematical results. He started developing his own thermos.

He graduated from Town Higher Secondary School in 1904. He received the K. Ranganatha Rao prize for mathematics. The Government Arts College awarded him a scholarship, but he spent most of his time focused on mathematics that he couldn’t concentrate on anything else.

Ramanujan had already started doing deep research by 1904. Based on the series, he calculated Euler’s constant to 15 decimals. Despite being entirely his own discovery, he started studying Bernoulli numbers.

In 1905, he attended Pachaiyappa’s College, but was again unsuccessful in his non-mathematical courses.

He started looking for a permanent job, which led to him interviewing a government official. Getting a job as a clerk at the Madras Port Trust improved his financial situation in March 1912.

The first papers he wrote were published in the Journal of the Indian Mathematical Society. Slowly, he was getting recognized for his work, and in 1913, he began correspondence with Godfrey Hardy, which led to a special scholarship from Madras University and a grant from Trinity College.


A few days later, he went to England to work with Hardy on some research. Littlewood and Hardy started working with him right away.

Littlewood and Hardy started looking through Ramanujan’s notebooks. Over the years 1903 – 1914, he devised thousands of identities, equations, and theorems for himself in the notebooks he brought from India.

Ramanujan became the first Indian mathematician to become a Royal Society Fellow in 1918. There are almost 4000 proofs, identities, conjectures, and equations he figured out in his short lifetime.


He died on 26 April 1920, in Madras, India.
