Sir Ronald Fisher (1890-1962) was the uncompromising genius who single-handedly created the architecture of modern science. A brilliant mathematician and a fierce intellectual combatant, he simultaneously founded the discipline of mathematical statistics and provided the essential quantitative proof for the theory of evolution.This comprehensive biography maps the extraordinary journey of the "Unruly Genius" from his days as a struggling student in Edwardian England and his breakthroughs at the Rothamsted Experimental Station-where he invented ANOVA and formalized experimental design-to his influential tenure at Cambridge, where he unraveled the secrets of human genetics.Fisher gave the world the language of certainty, yet he spent his career engaged in furious intellectual battles. He championed the P-value and Maximum Likelihood while waging decades-long wars against his rivals over the soul of statistical philosophy. Later in life, his controversial defense of eugenics and his skepticism in the smoking and lung cancer debate cemented his reputation as a formidable, often isolated, figure.Discover the life of the scientist whose ideas-from randomization to genetic linkage-are now so fundamental they are invisible, and explore the complex legacy of the man who redefined how we find objective truth.
