'''Sharadchandra Shankar Shrikhande''' (19 October 1917 – 21 April 2020) was an Indian mathematician with notable achievements in [[combinatorial mathematics]]. He was notable for his breakthrough work along with [[R. C. Bose]] and [[E. T. Parker]] in their disproof of the famous conjecture made by [[Leonhard Euler]] dated 1782 that there do not exist two mutually [[orthogonal]] [[latin square]]s of order 4n + 2 for any n.<ref>{{citation|title=Major Mathematical Conjecture Propounded 177 Years Ago Is Disproved|work=[[New York Times]]|date=26 April 1959|last=Osmundsen|first=John A.|url=https://www.nytimes.com/1959/04/26/archives/major-mathematical-conjecture-propounded-177-years-ago-is-disproved.html}}.

[[Shrikhande graph]]<ref>[http://www.win.tue.nl/~aeb/drg/graphs/Shrikhande.html Shrikhande graph ]</ref> is used in statistical designs.<br />
<br />
Shrikhande received a Ph.D. in the year 1950 from the [[University of North Carolina]] at Chapel Hill under the direction of R. C. Bose. Shrikhande taught at various universities in the USA and in India.<ref>{{citation|url=http://mospi.nic.in/mospi_stat_news_letter.htm|journal=Statistical Newsletter|date=July–September 2003|volume=XXVIII|issue=3|title=Prof. S.

Shrikhande was a professor of mathematics at [[Banaras Hindu University]], Banaras, and the founding head of the department of mathematics, [[University of Mumbai]] and the founding director of the Center of Advanced Study in Mathematics, Mumbai until he retired in 1978. He was a fellow of the [[Indian National Science Academy]], the [[Indian Academy of Sciences]] and the Institute of Mathematical Statistics, USA.<br />
