Ronald Fisher
Sir Ronald Aylmer FisherFRS (17 February 1890 – 29 July 1962) was an Englishstatistician, evolutionary biologist, and geneticist. He was described as "a genius who almost single-handedly created the foundations for modern statistical science".Richard Dawkins described him as "the greatest of Darwin's successors".
Professional years
[change | change source]In 1915, he invented the infinitesimal model. This is also known as the polygenic model. It is named this because it says traits are influenced by many genes. He defined the term "variance" for the first time in his paper, published in 1918.
In 1919 Fisher started work at Rothamsted Experimental Station at Harpenden, Hertfordshire. Here he started a major study of the extensive collections of data recorded over many years. This resulted in a series of reports under the general title Studies in crop variation.
This began a period of great productivity. Over the next seven years, he pioneered the principles of the design of experiments and elaborated his studies of the analysis of variance. He studied the statistics of small samples. Perhaps even more important, he began his systematic approach of the analysis of real data as the springboard for the development of new statistical methods.
He began to pay particular attention to the labour involved in the necessary computations, and developed practical methods. In 1925, his first book was published: Statistical methods for research workers. This went into many editions and translations in later years, and became a standard reference work for scientists in many disciplines. In 1935, this was followed by The design of experiments, which also became a standard.
His work on the theory of population genetics made him one of the three great figures of that field, together with Sewall Wright and J.B.S. Haldane. He was one of the founders of the neo-Darwinian modern evolutionary synthesis. In addi

Biography
R A Fisher's parents were Katie Heath, the daughter of a solicitor, and George Fisher, of Robinson and Fisher a firm of auctioneers in King Street, St James, London. 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.
Although he studied mathematics and astronomy at Cambridge, he was also interested in biology. In his second year as an undergraduate he began consulting senior members of the university about the possibility of forming a Cambridge University Eugenics Society. He graduated with distinction in the mathematical tripos of 1912. His tutor, however, believed he could have done better, writing [3]:-
... if he had stuck to the ropes he would have made a first class mathematician, but he would not.Awarded a Wollaston studentship, he continued his studies at Cambridge under Stratton on the theory of errors reading Airy's manual the
Ronald Fisher
British polymath (1890–1962)

Sir Ronald Aylmer FisherFRS (17 February 1890 – 29 July 1962) was a British polymath who was active as a mathematician, statistician, biologist, geneticist, and academic. For his work in statistics, he has been described as "a genius who almost single-handedly created the foundations for modern statistical science" and "the single most important figure in 20th century statistics". In genetics, Fisher was the one to most comprehensively combine the ideas of Gregor Mendel and Charles Darwin, as his work used mathematics to combine Mendelian genetics and natural selection; this contributed to the revival of Darwinism in the early 20th-century revision of the theory of evolution known as the modern synthesis. For his contributions to biology, Richard Dawkins declared Fisher to be the greatest of Darwin's successors. He is also considered one of the founding fathers of Neo-Darwinism. According to statistician Jeffrey T. Leek, Fisher is the most influential scientist of all time based on the number of citations of his contributions.
From 1919, he worked at the Rothamsted Experimental Station for 14 years; there, he analyzed its immense body of data from crop experiments since the 1840s, and developed the analysis of variance (ANOVA). He established his reputation there in the following years as a biostatistician. Fisher also made fundamental contributions to multivariate statistics.
Fisher founded quantitative genetics, and together with J. B. S. Haldane and Sewall Wright, is known as one of the three principal founders of population genetics. Fisher outlined Fisher's principle, the Fisherian runaway, the sexy son hypothesis theories of sexual selection, parental i
