1890 – 1962
Sir Ronald Aylmer Fisher (1890–1962) was a British statistician and geneticist whose work laid the foundations of modern statistical inference and population genetics. He unified Mendelian genetics with Darwinian natural selection, pioneering the mathematical framework for evolutionary theory known as the Modern Synthesis.
Developed foundational methods in statistical inference, including maximum likelihood estimation and analysis of variance (ANOVA)
Authored The Genetical Theory of Natural Selection (1930), a cornerstone of the Modern Synthesis
Formulated Fisher's fundamental theorem of natural selection
Established the mathematical basis for population genetics alongside Wright and Haldane
Developed the concept of Fisher information and contributed to the theory of experimental design
