Srinivasa Ramanujan (1887-1920 )
When he was about five years old, Ramanujan admitted to the primary school in Kumbakonam although he would attend several different primary schools before entering the Town High School in Kumbakonam in January 1898. At the Town High School, Ramanujan was the scholar student and showed himself an able all round scholar. In 1990, he began to work on his own on mathematics summing geometric and arithmetic series. In December 1889, he contracted smallpox. Continuing his mathematical work Ramanujan studied continued fractions and divergent series in 1908. At this stage, he became seriously ill again and underwent an operation in April 1909 after which he took him some considerable time to recover. He married on July 14, 1909 when his mother arranged for him to marry a ten-year-old girl S. Janaki Ammal. Ramanujan did not live with his wife, however, until she was twelve year old.
Ramanujan could not complete his college education because of illness. He was so interested in mathematics that he learned on his own. He found out new formulas for solving mathematical problems and wrote articles about them. Professor Hardy a scientist in the Cambridge Univesity saw one his article and impressed by his knowledge, took Ramanujan to England. Ramanujan was considered as the master of theory of numbers. The most outstanding of his contributions was his formula for p(n), the number of ‘partitions’ of ‘n’. It was in 1914, while he was working in Trinity College, he developed the ‘Number Theory’ and for his valuable contribution, was elected the ‘fellow of Trinity College’ on October 18, 1917. He returned to India in 1919 and began Research.
Ramanujan continued to develop his mathematical ideas and began to pose problems and solve problems in the journal of the Indian Mathematical society. He developed relations between elliptic modular equations in 1910. After publication of a brilliant research paper on Bernoulli numbers in 1911 in the Journal of the Indian Mathematical Society he gained recognition for his work. Despite his lack of a University education, he was becoming a well-known personality in the Madras area as a mathematical genius. He was died on April 26, 1920.
