Katie and George had seven children, four boys and three girls. After the birth of Geoffrey in 1876 and Evelyn in 1877, they named their third child, who was born the following year, Alan. He died at a very young age and Katie, being superstitious, decided that all their children from that time on would have a "y" in their name. Ronald Aylmer Fisher was the second of twins, but the older twin was still-born. In 1904 Ronald entered Harrow, but this was a difficult time for the fourteen year old boy, for his mother died in that year of acute peritonitis. Despite this, he excelled at Harrow winning the Neeld Medal in 1906 in a mathematical essay competition open to the whole school. Fisher was awarded a 80 scholarship from Caius and Gonville College, Cambridge, which was necessary to finance his studies since his father had lost his fortune. In October 1909 he matriculated at Cambridge.

Sir Ronald Aylmer Fisher Ronald Fisher received a B.A. in astronomy from Cambridge in 1912. There he studied the theory of errors under Stratton using Airy's manual Theory of Errors . It was Fisher's interest in the theory of errors in astronomical observations that eventually led him to investigate statistical problems. Fisher gave up being a mathematics teacher in 1919 to work at the Rothamsted Agricultural Experiment Station where he worked as a biologist and made many contributions to both statistics and genetics. He had a long dispute with Pearson and he turned down a post under him, choosing to go to Rothamsted instead. There he studied the design of experiments by introducing the concept of randomisation and the analysis of variance, procedures now used throughout the world. Fisher is considered the founder of modern statistics because of his many important contributions to that field. In 1921, he introduced the concept of likelihood and the maximum likelihood estimator. He also developed methods suitable for small samples, like those of Gosset, discovered of the precise distributions of many sample statistics, invented of analysis of variance, and studied hypothesis testing. In 1922 he gave a new definition of statistics. Its purpose was the reduction of data and he identified 3 fundamental problems: specification of the kind of population that the data came from, parameter estimation, and distributional problems.

In 1921 he introduced the concept of likelihood. The likelihood of a parameter is proportional to the probability of the data and it gives a function which usually has a single maximum value, which he called the maximum likelihood.

Edwards Deming Walter A. Shewhart Bill Hunter George Box Sir Ronald Aylmer Fisher, (17 February 1890 - 29 July 1962) was an extraordinarily talented evolutionary biologist, geneticist and statistician. He has been described by Richard Dawkins as "The greatest of Darwin’s successors," and the historian of statistics Anders Hald said "Fisher was a genius who almost single-handedly created the foundations for modern statistical science." Contributions to Statistics Fisher invented the techniques of maximum likelihood and analysis of variance, was a pioneer in the design of experiments , and originated the concepts of sufficiency, ancillarity, and Fisher information, making him a major figure in 20th century statistics. His article "On a distribution yielding the error functions of several well known statistics" presented Karl Pearson's chi-squared and Student's t in the same framework as the normal distribution and his own analysis of variance distribution z. Fisher's book Statistical methods for research workers showed how to use these distributions. His work on the theory of population genetics also made him one of the three great figures of that field, together with Sewall Wright and J. B. S. Haldane, and as such one of the founders of the neodarwinian modern synthesis. See also Fisher's linear discriminator.

FISHER Sir Ronald Aylmer, anglais, 1890-1962 On ne le confondra pas avec le mathématicien autrichien Ernst Fischer Fisher étudia les mathématiques et l'astronomie à l'université de Cambridge (Angleterre). Il étudia également la biologie, la génétique selon Galton et les lois de Mendel (qui ne furent publiées qu'en 1900) , ce qui le conduisit aux statistiques et au calcul des probabilités. Fisher entretint, avec son compatriote Pearson , éminent statisticien, des relations orageuses dues à des désaccords sur les méthodes d'analyse. Il est l'auteur d'importants travaux novateurs sur la théorie des erreurs et la théorie de l'estimation : calculs de probabilités sur des échantillons de population.
