The year 1950 can be considered as an important year in the history of Statistics at Banaras Hindu University when the teaching of the subject began for the first time at undergraduate and diploma levels. Another important activity took place in the history of the subject in the year 1962 when the teaching of Statistics was introduced at the post graduate level. Then teaching of Applied Statistics in the Section at undergraduate level started in the year 1970. Initially, Statistics was a section of the Department of Mathematics and Dr. Pran Nath was given the responsibility of teaching of the subject. Professor S. S. Shrikhande, a renowned name in the subject, later on became the In- charge of the Statistics Section, who was succeeded by Professor M. N. Ghosh in the year 1963. After Prof. Ghosh, all the responsibility went into the hands of Professor S. N. Singh. The faculty members of those days worked diligently under the noble guidance of Professor Singh towards the development of the Section and it was because of their untiring efforts that a full-fledged Statistics Department came into existence in January 1984. Professor S. N. Singh was appointed the first Head of the newly created Department of Statistics.
