He entered Harrow School age 14 and won the school's Neeld Medal in mathematics. In 1909, he won a scholarship to study Mathematics at Gonville and Caius College, Cambridge. In 1912, he gained a First in Astronomy."Sir Ronald Aylmer Fisher", Statistics Courses, University of Minnesota In 1915 he published a paper The evolution of sexual preferenceJOURNAL, Fisher, R. A., 1915, The evolution of sexual preference, Eugenic Review, 7, 3, 184â€“192, 2987134, 21259607, on sexual selection and mate choice.Career
During 1913â€“1919, Fisher worked for six years as a statistician in the City of London and taught physics and maths at a sequence of public schools, at the Thames Nautical Training College, and at Bradfield College. There he settled with his new bride, Eileen Guinness, with whom he had two sons and six daughters.Box, R. A. Fisher, pp 35â€“50In 1918 he published "The Correlation Between Relatives on the Supposition of Mendelian Inheritance", in which he introduced the term variance and proposed its formal analysis. He put forward a genetics conceptual model showing that continuous variation amongst phenotypic traits measured by biostatisticians could be produced by the combined action of many discrete genes and thus be the result of Mendelian inheritance. This was the first step towards establishing population genetics and quantitative genetics, which demonstrated that natural selection could change allele frequencies in a population, resulting in reconciling its discontinuous nature with gradual evolution.Box, R. A. Fisher, pp 50â€“61 Joan Box, Fisher's biographer and daughter says that Fisher had resolved this problem already in 1911.R A Fisher: the life of a scientist Preface www-history.mcs.st-and.acRothamsted Experimental Station, 1919â€“1933
In 1919, he began working at the Rothamsted Experimental Station for 14 years, where he analysed its immense data from crop experiments since the 1840s, and developed the analysis of variance (ANOVA). In 1919, he was offered a position at the Galton Laboratory in University College London led by Karl Pearson, but instead accepted a temporary job at Rothamsted in Harpenden to investigate the possibility of analysing the vast amount of crop data accumulated since 1842 from the "Classical Field Experiments". He analysed the data recorded over many years and in 1921, published Studies in Crop Variation, and his first application of the analysis of variance ANOVA. In 1928, Joseph Oscar Irwin began a three-year stint at Rothamsted and became one of the first people to master Fisher's innovations.Between 1912 and 1922 Fisher recommended, analyzed (with flawed attempts at proofs) and vastly popularized Maximum likelihood.BOOK, Parametric statistical theory, Pfanzagl, Johann, R., HambÃ¶ker, 1994, Walter de Gruyter, Berlin, 978-3-11-013863-4, 207â€“208, (File:Ronald Fisher 1912 graduation Cambridge.JPG|thumb|upright|On graduating from Cambridge University, 1912)(File:Peacock Flying.jpg|thumb|The peacock tail in flight, the classic example of a Fisherian runaway)(File:Rothamstead_Research_Centre_-_geograph.org.uk_-_1724254.jpg|thumb|Rothamsted Research)Fisher's 1924 article On a distribution yielding the error functions of several well known statistics presented Pearson's chi-squared test and William Gosset's Student's t-distribution in the same framework as the Gaussian distribution and is where he developed Fisher's z-distribution a new statistical method, commonly used decades later as the F distribution. He pioneered the principles of the design of experiments and the statistics of small samples and the analysis of real data.In 1925 he published Statistical Methods for Research Workers, one of the 20th century's most influential books on statistical methods.JOURNAL, Conniffe, Denis, 1991, R.A. Fisher and the development of statisticsâ€”a view in his centenary year, Journal of the Statistical and Social Inquiry Society of Ireland, 26, 3, 55â€“108, Fisher's methodBOOK, Fisher, R.A., 1925, Statistical Methods for Research Workers, Oliver and Boyd (Edinburgh),weblink 978-0-05-002170-5, JOURNAL, 10.2307/2681650, Fisher, R.A., Fisher, R. A, Questions and answers #14, The American Statistician, 1948, 2, 30â€“31, 5, 2681650, is a technique for data fusion or "meta-analysis" (analysis of analyses). This book also popularized the p-value, and plays a central role in his approach. Fisher proposes the level p=0.05, or a 1 in 20 chance of being exceeded by chance, as a limit for statistical significance, and applies this to a normal distribution (as a two-tailed test), thus yielding the rule of two standard deviations (on a normal distribution) for statistical significance. The 1.96, the approximate value of the 97.5 percentile point of the normal distribution used in probability and statistics, also originated in this book."The value for which P=.05, or 1 in 20, is 1.96 or nearly 2 ; it is convenient to take this point as a limit in judging whether a deviation is to be considered significant or not."BOOK, Ronald, Fisher, Ronald Fisher, Statistical Methods for Research Workers, 1925, 978-0-05-002170-5, 47, Oliver and Boyd, Edinburgh, In Table 1 of the work, he gave the more precise value 1.959964.BOOK, Ronald, Fisher, Ronald Fisher, Statistical Methods for Research Workers, 1925, 978-0-05-002170-5, Oliver and Boyd, Edinburgh, Statistical Methods for Research Workers, , Table 1In 1928, Fisher was the first to use diffusion equations to attempt to calculate the distribution of allele frequencies and the estimation of genetic linkage by maximum likelihood methods among populations.JOURNAL, R.

A core work of the neo-Darwinian modern evolutionary synthesis,BOOK, Richard Dawkins: How A Scientist Changed the Way We Think, Grafen, Alan, Alan Grafen, Ridley, Mark, 2006, Oxford University Press, New York, New York, 978-0-19-929116-8, 69, it helped define population genetics, which Fisher founded alongside Sewall Wright and J. B. S. Haldane, and revived Darwins neglected idea of sexual selection.Sexual Selection and Summary of Population Genetics Accessed from uscs.edu 2-08-2015 One of Fisher's favorite aphorisms was "Natural selection is a mechanism for generating an exceedingly high degree of improbability."The Genetical Theory of Natural Selection. It was first reported in 1936 by Julian Huxley and often repeated in Huxley's work (e.g., 1942, 1954) until it finally passed into the language unattributed through the writings of C. H. Waddington, Gavin de Beer, Ernst Mayr, and Richard Dawkins.Fisher's fame grew and he began to travel and lecture widely. In 1931, he spent six weeks at the Statistical Laboratory at Iowa State College where he gave three lectures per week, and met many American statisticians, including George W. Snedecor. He returned there again in 1936.{{citation needed|date=July 2017}}University College London, 1933â€“39
In 1933, Fisher became the head of the Department of Eugenics at University College London.Department History, Department of Statistics, University College London. In 1935, he published The Design of Experiments, which was "also fundamental, [and promoted] statistical technique and application... The mathematical justification of the methods was not stressed and proofs were often barely sketched or omitted altogether .... [This] led H.B. Mann to fill the gaps with a rigorous mathematical treatment".BOOK, Mann, H.B., Analysis and design of experiments: Analysis of variance and analysis of variance designs, Dover, New York, N. Y., 1949, 32177, harv, In this book Fisher also outlined the Lady tasting tea, now a famous design of a statistical randomized experiment which uses Fisher's exact test and is the original exposition of Fisher's notion of a null hypothesis.Fisher, R. A. (1971) The Design of Experiments. Chapter II. The Principles of Experimentation, Illustrated by a Psycho-physical Experiment, Section 8. The Null HypothesisOED quote: 1935 R. A. Fisher, The Design of Experiments ii. 19, "We may speak of this hypothesis as the 'null hypothesis', and it should be noted that the null hypothesis is never proved or established, but is possibly disproved, in the course of experimentation."The same year he also published a paper on fiducial inferenceJOURNAL, Fisher, R. A., 1935, The fiducial argument in statistical inference, Annals of Eugenics, 8, 4, 391â€“398, 10.1111/j.1469-1809.1935.tb02120.x, R. A. Fisher's Fiducial Argument and Bayes' Theorem by Teddy Seidenfeld and applied it to the Behrensâ€“Fisher problem, the solution to which, proposed first by Walter Behrens and a few years later by Fisher, is the Behrensâ€“Fisher distribution.In 1936 he introduced the Iris flower data set as an example of discriminant analysis.JOURNAL, R.

Out of this also came the Fisherâ€“Kolmogorov equation.Fisher 2In 1937, he visited the Indian Statistical Institute in Calcutta, and its one part-time employee, P. C. Mahalanobis, often returning to encourage its development. He was the guest of honour at its 25th anniversary in 1957, when it had 2000 employees.Box, R. A. Fisher, p 337In 1938, Fisher and Frank Yates described the Fisherâ€“Yates shuffle in their book Statistical tables for biological, agricultural and medical research.BOOK, Fisher, Ronald A., Ronald A.

R. Rao. Their description of the algorithm used pencil and paper; a table of random numbers provided the randomness.University of Cambridge, 1940â€“1956
In 1943, along with A.S. Corbet and C.B. Williams he published a paper on relative species abundance where he developed the logseries to fit two different abundance data setsJOURNAL, Fisher, R. A., Corbet, A. S., Williams, C. B., 1943, The relation between the number of species and the number of individuals in a random sample of an animal population, Journal of Animal Ecology, 12, 1, 42â€“58, 10.2307/1411, 1411, In the same year he took the Balfour Chair of Genetics where the Italian researcher Luigi Luca Cavalli-Sforza was recruited in 1948, establishing a one-man unit of bacterial genetics.In 1936, Fisher used a Pearson's chi-squared test to analyze Mendel's data and concluded that Mendel's results with the predicted ratios were far too perfect, suggesting that adjustments (intentional or unconscious) had been made to the data to make the observations fit the hypothesis.JOURNAL, R. A., Has Mendel's work been rediscovered?, Annals of Science, Fisher, 1, 2, 115â€“126, 1936, 10.1080/00033793600200111, Later authors have claimed Fisher's analysis was flawed, proposing various statistical and botanical explanations for Mendel's numbers.BOOK, Franklin, Allan, Edwards, A.

A. Fisher, pp 93â€“166 with various editions and translations, becoming a standard reference work for scientists in many disciplines. In ecological genetics he and E. B. Ford showed how the force of natural selection was much stronger than had been assumed, with many ecogenetic situations (such as polymorphism) being maintained by the force of selection.During this time he also worked on mouse chromosome mapping; breeding the mice in laboratories in his own house.JOURNAL, D.

This is to misjudge the man. He was not above accepting financial reward for his labours, but the reason for his interest was undoubtedly his dislike and mistrust of puritanical tendencies of all kinds; and perhaps also the personal solace he had always found in tobacco."He gave the 1953 Croonian lecture on population genetics.Croonian Lecture: Population Genetics by Ronald Fisher, published by The Royal Society PublishingIn the winter of 1954â€“1955 Fisher met Debabrata Basu, the Indian statistician who wrote in 1988, "With his reference set argument, Sir Ronald was trying to find a via media between the two poles of Statistics â€“ Berkeley and Bayes.The term "Berkeley" has several meanings, here. Basu refers to the leadership of Jerzy Neyman's department of statistics at the University of California at Berkeley in the world of frequentist statistics. Secondly, Basu alludes to the British philosopher George Berkeley who criticized the use of infinitesimals in mathematical analysis; Berkeley's criticisms were answered by Thomas Bayes in a pamphlet. My efforts to understand this Fisher compromise led me to the likelihood principle".Page xvii in Ghosh (ed.)Adelaide, 1957â€“1962
(File:Ronald Aylmer Fisher.jpg|thumb|Memorial plaque over his mortal remains, lectern-side aisle of St Peter's Cathedral, Adelaide)In 1957, a retired Fisher emigrated to Australia, where he spent time as a senior research fellow at the Australian Commonwealth Scientific and Industrial Research Organisation (CSIRO) in Adelaide.

Fisher was noted for being loyal, and was seen as a patriot, a member of the Church of England, politically conservative, as well as a scientific rationalist. He developed a reputation for carelessness in his dress and was the archetype of the absent-minded professor. H. Allen Orr describes him in the Boston Review as a "deeply devout Anglican who, between founding modern statistics and population genetics, penned articles for church magazines".Gould on God: Can religion and science be happily reconciled? bostonreview.net In a 1955 broadcast on Science and Christianity, he said:{{cquote|The custom of making abstract dogmatic assertions is not, certainly, derived from the teaching of Jesus, but has been a widespread weakness among religious teachers in subsequent centuries. I do not think that the word for the Christian virtue of faith should be prostituted to mean the credulous acceptance of all such piously intended assertions. Much self-deception in the young believer is needed to convince himself that he knows that of which in reality he knows himself to be ignorant.

File:RonaldFisher1912.jpg|thumb|upright|As a steward at the First International Eugenics ConferenceInternational Eugenics ConferenceIn 1910 Fisher joined the Eugenics Society (UK) at University of Cambridge, whose members included John Maynard Keynes, R. C. Punnett, and Horace Darwin. He saw eugenics as addressing pressing social and scientific issues that encompassed and drove his interest in both genetics and statistics. During World War I Fisher started writing book reviews for the Eugenic Review and volunteered to undertake all such reviews for the journal, being hired for a part-time position.The last third of The Genetical Theory of Natural Selection focussed on eugenics, attributing the fall of civilizations to the fertility of their upper classes being diminished, and used British 1911 census data to show an inverse relationship between fertility and social class, partly due, he claimed, to the lower financial costs and hence increasing social status of families with fewer children. He proposed the abolition of extra allowances to large families, with the allowances proportional to the earnings of the father. He served in several official committees to promote eugenics. In 1934, he resigned from the Eugenics Society over a dispute about increasing the power of scientists within the movement.WEB, Series 12.

In 1950, Fisher opposed UNESCO's The Race Question, believing that evidence and everyday experience showed that human groups differ profoundly "in their innate capacity for intellectual and emotional development" and concluded that the "practical international problem is that of learning to share the resources of this planet amicably with persons of materially different nature", and that "this problem is being obscured by entirely well-intentioned efforts to minimize the real differences that exist". The revised statement titled "The Race Concept: Results of an Inquiry" (1951) was accompanied by Fisher's dissenting commentary.Legacy

- Fisherâ€“Tippett distribution
- Von Misesâ€“Fisher distribution
- Inverse probability, a term Fisher used in 1922, referring to "the fundamental paradox of inverse probability" as the source of the confusion between statistical terms which refer to the true value to be estimated, with the actual value arrived at by estimation, which is subject to error.JOURNAL, Fisher, R. A., On the Mathematical Foundations of Theoretical Statistics, Philos. Trans. R. Soc. London A, 1922, 222A, 309â€“368,

Recognition
Fisher was elected to the Royal Society in 1929. He was made a Knight Bachelor by Queen Elizabeth II in 1952 and awarded the Linnean Society of London Darwinâ€“Wallace Medal in 1958.He won Copley Medal and the Royal Medal. He was an Invited Speaker of the ICM in 1924 in Toronto and in 1928 in Bologna.BOOK, Fisher, R. A., On a property connecting the Ï‡2 measure of discrepancy with the method of maximum likelihood, In: Atti del Congresso Internazionale dei Matematici: Bologna del 3 al 10 de settembre di 1928, vol. 6, 95â€“100, In 1950, Maurice Wilkes and David Wheeler used the Electronic Delay Storage Automatic Calculator to solve a differential equation relating to gene frequencies in a paper by Ronald Fisher.Gene Frequencies in a Cline Determined by Selection and Diffusion, R. A. Fisher, Biometrics, Vol. 6, No. 4 (Dec., 1950), pp. 353â€“361 This represents the first use of a computer for a problem in the field of biology. The Kent distribution (also known as the Fisherâ€“Bingham distribution) was named after him and Christopher Bingham in 1982 while Fisher kernel was named after Fisher in 1998.Tommi Jaakkola and David Haussler (1998), Exploiting Generative Models in Discriminative Classifiers. In Advances in Neural Information Processing Systems 11, pages 487–493. MIT Press. {{isbn|978-0-262-11245-1}} PS, CiteseerThe R. A. Fisher Lectureship is a North American annual lecture prize, established in 1963. On 28 April 1998 a minor planet, 21451 Fisher, was named after him.JPL Small-Body Database Browser Source is NASAAnders Hald called Fisher "a genius who almost single-handedly created the foundations for modern statistical science",BOOK, Hald, Anders, Anders Hald, 1998, A History of Mathematical Statistics, Wiley, New York, 978-0-471-17912-2, while Richard Dawkins named him "the greatest biologist since Darwin": Not only was he the most original and constructive of the architects of the neo-Darwinian synthesis, Fisher also was the father of modern statistics and experimental design. He therefore could be said to have provided researchers in biology and medicine with their most important research tools, as well as with the modern version of biology's central theorem.WEB, Dawkins, Richard, Richard Dawkins, 2010, Who is the Greatest Biologist Since Darwin? Why?,weblink Edge, Who is the greatest biologist since Darwin? That's far less obvious, and no doubt many good candidates will be put forward. My own nominee would be Ronald Fisher. Not only was he the most original and constructive of the architects of the neo-Darwinian synthesis. Fisher also was the father of modern statistics and experimental design. He therefore could be said to have provided researchers in biology and medicine with their most important research tools, as well as with the modern version of biology's central theorem., Geoffrey Miller said of him:To biologists, he was an architect of the "modern synthesis" that used mathematical models to integrate Mendelian genetics with Darwin's selection theories. To psychologists, Fisher was the inventor of various statistical tests that are still supposed to be used whenever possible in psychology journals. To farmers, Fisher was the founder of experimental agricultural research, saving millions from starvation through rational crop breeding programs.Miller, Geoffrey (2000).
