Samarendra Nath Roy or S. N. Roy (born 1906 in Dhaka, East Bengal – 1966) was an Indian mathematician. He was the first of two children. His father, Kali Nath Roy was a freedom fighter and the Chief Editor of the newspaper "TRIBUNE".
Roy came first in the M.Sc. examinations in applied mathematics at the University of Calcutta.
At that time Professor P. C. Mahalanobis was the director of the new (1931) Indian Statistical Institute. Several talented young scholars including J. M. Sengupta, H. C. Sinha, Raj Chandra Bose, S. N. Roy, K. R. Nair, K. Kishen and C. R. Rao, joined to form an active group of statisticians under Prof. Mahalanobis. S. N. Roy was one of the very early students of Prof. Prasanta Chandra Mahalanobis, who initiated some of the early works in Statistics. He was well known for his contribution to multivariate statistical analysis. His dissertation included the Post master's work at the Indian Statistical Institute where he worked under Mahalanobis.
It was Bose who first went to the United States as a visiting professor at Columbia University and the University of North Carolina, Chapel Hill in 1947. Roy later joined him at the University of North Carolina Chapel Hill and later became Professor of Statistics. S. N. Roy had 15 doctorate students there from 1951 till 1963.
