Being one of the first members of the first Planning Commission of free India, Mahalanobis was born in Kolkata on 29 June 1893. Schooled and brought up in the city, he joined Kolkata's Presidency College in 1908 where he was taught by the likes of Jagadish Chandra Bose and Prafulla Chandra Ray. Mahalanobis soon moved to England after his graduation and went on to study further at King's College, Cambridge. He soon discovered the utility of statistics to problems in meteorology and anthropology, beginning to work on problems on his journey back to India.

In 1939, he invented what came to be known as the Mahalanobis distance, which soon became key in cluster analysis and classification techniques in statistics. He introduced the concept of pilot surveys and acquainted many with the system of sampling. The statistician also contributed by introducing a method for estimation of crop yields using statistical sampling.

Mahalanobis also founded the Indian Statistical Institute along with three others in 1932 and contributed to the design of large-scale surveys. The Institute was initially in the Physics Department of the Presidency College, the college where Mahalanobis was a guest lecturer. It grew gradually but consistently to be declared an institute of national importance and a deemed university in 1959.

Mahalanobis died on 28 June 1972, a day before his seventy-ninth birthday.

Many would have called it quits at his age but not Mahalanobis. Even at that time he was still actively continuing his research work and serving his duties as the Secretary and Director of the Indian Statistical Institute alongside being the Honorary Statistical Advisor to the Cabinet of the Government of India.
