Sharadchandra Shankar Shrikhande was born on October 19, 1917 in Sagar, Madhya Pradesh, India. He is notable for his work along with R. C. Bose and E. T. Parker in their disproof of the famous conjecture made by Leonhard Euler in 1782.

Biography

Shrikhande taught at various universities in the US and in India. [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. S. Shrikhande – An Outstanding Statistician|page=3.] Currently (2008), he resides in Michigan, US. He is father of four children, and has five grandchildren, and three great grandchildren.

Shrikande served as a Professor of Mathematics at Banaras Hindu University, Banaras. He was Head of the Department of Mathematics, University of Mumbai and the Director of the Center of Advanced Study in Mathematics, Mumbai since its inception in 1963 until he retired in 1978.

Shrikhande's Ph.D. students were S. Bhagavan Das, Vasanti N. Bhat-Nayak and Navin M. Singhi.mathgenealogy|name=Shartchandra S. Shrikhande|id=47278.]

Contributions to mathematics

His specialty was combinatorics and statistical designs. He is notable for his 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 squares of order 4n + 2 for every n.

One of his children, [http://www.cst.cmich.edu/units/mth/gradinfo/pp/MTHShrikhande.html Mohan Shrikhande] , is a Professor of Combinatorial Mathematics at Central Michigan University in Mt. Pleasant, Michigan.
