Sir Ronald A Fisher, FRS (17 February 1890 – 29 July 1962) was an English statistician, biologist and geneticist who used statistical procedures in designing scientific experiments in biological sciences and genetics.
R A Fisher visited Indian Statistical Institute eight times. He made his first visit to India in the winter of 1937-38, at the initiative of P C Mahalanobis. Dr. Shyama Prasad Mukherjee, Vice-Chancellor of Calcutta University, wrote to R A Fisher, inviting him to come during December 1937 and January 1938 in Calcutta University. Fisher accepted this and asked for an honorarium of £ 200 and all other expenses.

Fisher’s last visit to the Institute took place in February 1962.
During his several visits Fisher met with the Viceroy and other British dignitaries and lent the weight of his prestige to spread appreciation of statistics in the service of India. He conducted a large number of seminar meetings on statistical research and delivered lectures in the Institute. He helped ISI to work with large scale random sampling for estimating yield and acreage of crops. In 1954-55 he delivered series of lectures on Logic of statistical inference at ISI. He was in Lahore Branch of the ISI and visited the Irrigation Research Laboratory with a view to advising the Govt. of the Punjab in regard to the difficult problem of the rising of water level in irrigated areas. Fisher acted as moderator for the first Statistician’s Diploma examination in 1937.Fisher was a close friend and collaborator of P C Mahalanobis. It was he who proposed the name of Mahalanobis for the Fellowship of the Royal Society. He also proposed Mahalanobis for the Weldon Medal. Fisher had compared the Institute to the ‘banyan tree’ in reference to its activities which in spite of their diversity had an underlying unity of purpose – the promotion of research and of knowledge. R A Fisher delivered the First Convocation Speech of the Institute held on 12 February 1962. He also delivered the Anniversary Speech on the occasion of the Silver Jubilee celebrations of the Statistical Institute. Fisher supported the journal Sankhya by contributing his writings to its publication. He termed the new concept of statistics ‘as a key technology of our age’.
