'''Kanakanahalli Ramachandra''' (18 August 1933 – 17 January 2011) was an Indian mathematician working in both [[analytic number theory]] and [[algebraic number theory]].<br />
<br />
==Early career==<br />
After his father's death at age 13, he had to look for a job. Ramachandra worked as a clerk at the Minerva Mills where Ramachandra's father had also worked. In spite of taking up a job quite remote from mathematics, Ramachandra studied number theory all by himself in his free time; especially the works of [[Ramanujan]].{{fact|date=November 2018}}<br />
<br />
Ramachandra completed his graduation and post graduation from [[Central College, Bangalore]].{{fact|date=November 2018}}<br />
<br />
Later, he worked as a lecturer in BMS College of Engineering. Ramachandra also served a very short stint of only six days as a teacher in the [[Indian Institute of Science]], Bangalore.{{fact|date=November 2018}}<br />
<br />
Ramachandra went to the [[Tata Institute of Fundamental Research]] (TIFR), [[Bombay]], for his graduate studies in 1958. He obtained his PhD from [[University of Mumbai]] in 1965; his doctorate was guided by [[K. G. Ramanathan]].<ref>http://genealogy.math.ndsu.nodak.edu/id.php?id=98044</ref><br />
<br />
==Later career==<br />
Between the years 1965 and 1995 he worked at the [[Tata Institute of Fundamental Research]] and after retirement joined the [[National Institute of Advanced Studies]], Bangalore where he worked till 2011, the year he died. During the course of his lifetime, he published over 200 articles, of which over 170 have been catalogued by [[Mathematical Reviews]].<br />
<br />
His work was primarily in the area of prime number theory, working on the [[Riemann zeta function]] and allied functions. Apart from prime number theory, he made substantial contributions to the theory of [[transcendental number theory]], in which he is known for his proof of the [[six exponentials theorem]], achieved independently of [[Serge Lang]]. He also contributed to many other areas of number theory.<br />
<br />
In 1978 he founded the [[Hardy–Ramanujan journal]], and published it on behalf of the Hardy–Ramanujan society until his death.<br />
