 Srinivasa Ramanujan Iyengar (December 22, 1887 –
April 26, 1920) was an Indian mathematician.
 He is an Indian mathematician who lived during
the British Rule in India. He is considered to be one of
the most talented mathematicians in recent history.
 His father's name was K.Srinivasa iyengar and mother's
name was Komalatammal.
 He was married to Janakiammal and did not have
children.
 He died at the age of 32 due to tuberculosis.

Nadu, India.
• His father Srinivas Iyengar was an accountant in a sari shop.

His mother, Komalatammal, was a domestic housewife as well
as a local temple singer.
• He was very fond of his mother.
• He lived in Kumbakonam village initially with his family.

LIFE BEFORE EUROPE
 Ramanujan was married but unemployed and was searching for a job. He
stayed at a friend's house while he went from door to door around Madras
looking for a clerical position.
 He was hired as a clerk for the accountant named Narayan Iyer whose interest
was sparked on seeing Ramanujans notebooks.He worked there from 1912 to
1914 and lived with his mother and wife.
 In 1913 he secured a research position at Madras University, and moved with
his family to Triplicane.
 In the spring of 1913, Narayana Iyer, Ramachandra Rao and E. W.

Middlemast tried to present Ramanujan's work to British mathematicians.
 On 16 January 1913, Ramanujan wrote to G. H. Hardy who helped plan his

trip to Cambridge University in Europe.
Miserable times
• Upon arrival at Cambridge, Ramanujan encounters various forms of
racial prejudice and finds his adjustment to life in England more difficult
than expected.
• Hardy, though much impressed by Ramanujan's abilities, remains
concerned about Ramanujan's ability to communicate effectively due to
his lack of experience in writing proofs, but with perseverance, he
manages to get Ramanujan published in a major journal.
• In the meantime, Ramanujan is diagnosed with tuberculosis and his
frequent letters home to his wife remain unanswered after many months.
• Hardy continues to see much more promise in Ramanujan.
• However, he remains unaware of the personal difficulties his student is
having with his housing and with his lack of contact with his family
back home in India.
• Ramanujan's health worsens while he continues delving into deeper and
more profound research interests in mathematics under the guidance of
Hardy and others at Cambridge.
Success…
• Janaki, after much elapsed time, wonders why she has not heard from
Ramanujan and eventually discovers that his mother has been
intercepting his letters, and withholding hers to him.
• Hardy makes special efforts to get Ramanujan's now recognizably
exceptional mathematical skills accepted by the university, by
nominating Ramanujan for a fellowship of Trinity College.
• At first, Hardy fails for reasons related to college politics and racial
prejudice.
• By gaining the support of key members of the college, Hardy again
successfully nominates Ramanujan as a Fellow of the Royal Society,
thereby forcing his acceptance as a fellow of Trinity.
• Ramanujan is eventually reunited with his family in India, though his
declining health, exacerbated by poor housing and harsh winter weather
in England, ultimately takes its toll and leads to his death aged 32, soon
after his recognition as a mathematician of international merit and
importance.
HARDSHIPS FACED AS A BRAHMIN
 Crossing the seas was forbidden.
 Being a pure vegetarian in

Cambridge Europe he had to cook
his own meals rather than have
meals from the hall.
 Experienced racism.
FACT : THE HARDY-RAMANUJAN NUMBER
1729
Thank you…Hope you all are inspired by the story of this great personality !!
