Ramanujan mainly worked in analytical number theory and is famous for many summation formulas involving constants such as π, prime numbers and partition function. Often, his formulas were stated without proof and were only later proven to be true.

February 3 Th letter to G. H. HardyGodfrey Harold Hardy ( February 7, 1877 December 1, 1947) was a prominent British mathematician, known for his achievements in number theory and mathematical analysis. Non-mathematicians know him for two things: A Mathematician's Apology his essay from 19 contained a long list of theorems without proof. After some initial skepticism, Hardy replied and invited Ramanujan to England. As an orthodox Brahmin, Ramanujan consulted the astrological data for his journey, because his mother was horrified that he would lose his caste by traveling to foreign shores.
A fruitful collaboration, which Hardy described as "the one romantic incident in my life", soon developed. Hardy said of some of Ramanujan's formulas, which he could not understand, that "a single look at them is enough to show that they could only be written down by a mathematician of the highest class. They must be true, for if they were not true, no one would have had the imagination to invent them." Hardy, a prominent mathematician in his own right, stated in an interview by Paul Erdos that his greatest contribution to mathematics was the discovery of Ramanujan.
Plagued by health problems all his life, Ramanujan's condition worsened in England, perhaps exacerbated the scarcity of vegetarian food during the First World War. He was also diagnosed with tuberculosis (Henderson, 1996) and a severe vitamin deficiency, though a 1994 analysis of Ramanujan's medical records and symptoms by Dr. D.A.B Young concluded that it was much more likely he had hepatic amoebiasis, a parasitic infection of the liver. This is also supported by the fact that Ramanujan spent time in Madras, a coastal city where the disease was widespread. It was a difficult disease to diagnose, but once diagnosed was readily curable (Berndt, 1998). He returned to India in 1919 and died soon after in Kumbakonam. His wife S. Janaki Ammal lived outside Chennai (formerly Madras) until her death in 1994. Janaki had been nine when they were married, a fairly common practice in India at the time. (Henderson, 1996)
