'''Kollagunta Gopalaiyer Ramanathan''' (13 November 1920 – 10 May 1992) was an [[India]]n [[mathematician]] known for his work in [[number theory]]. His contributions are also to the general development of mathematical research and teaching in India.<br />
<br />
==K. G. Ramanathan's early life and his family==<br />
K. G. Ramanathan was born in [[Hyderabad, India|Hyderabad]] in South India. He completed his B.A. and M.A. in mathematics at [[Osmania University]] and the [[University of Madras]] respectively before going to [[Princeton University|Princeton]] to earn his Ph.D; his advisor was [[Emil Artin]]. At Princeton, Ramanathan also worked with [[Hermann Weyl]] and [[Carl Siegel]]. Thereafter he returned to India to team up with [[K. S. Chandrasekharan]] at the [[Tata Institute of Fundamental Research]] (TIFR) at [[Colaba]] in 1951. At Princeton, for about two years, Ramanathan's neighbour was [[Albert Einstein]], the legendary physicist. He used to sing Carnatic songs of [[Tyagaraja]] to Einstein for entertainment.<br />
