Prasant Chandra Mahalanobis: The Architect of Indian Planning: Many distinguished thinkers contributed to the formulation of our five year plans. Among them, the name of statistician, Prasanta Chandra Mahalanobis stands out. Planning, in real sense of the term, began with the Second Five Year Plan. The Second Plan, a landmark contribution to development planning in general, laid down the basic ideas regarding goals of Indian planning; this plan was based on the ideas of Mahalonobis. In that sense he can be regarded as the architect of Indian Planning.Mahalanobis was born in \\\\(1893\\\\) in Kolkata. He was educated at the Presidency College in Kolkata and at Cambridge University in England. His contributions to the subject of statistics brought him international fame. In \\\\(1946\\\\), he was made a Fellow (member) of Britain's Royal Society, one of the most prestigious organisations of scientists; only the most outstanding scientists are made members of this society.Mahalanobis established the Indian Statistical Institute(ISI) in Kolkata and started a jorunal, Sankhye, which still serves as a respect forum for statisticians to their ideas.
