Sir Ronald Aylmer Fisher FRS (17 February 1890 – 29 July 1962), who published as R. A. Fisher, was a British statistician and geneticist.
He lived at 56 Kempshott Road, Streatham.
Ronald Fisher FRS, born, was "a genius who almost single-handedly created the foundations for modern statistical science". He also brought together the work of Mendel and Darwin and has been called "the greatest of Darwin’s successors" ( Source Royal Society)
Fisher was born in East Finchley in London, England, into a middle class household; his father, George, was a successful partner in Robinson & Fisher, auctioneers and fine art dealers. He was one of twins with the other being still-born and grew up the youngest with three sisters and one brother. From 1896 until 1904 they lived at Inverforth House in London, where English Heritage installed a blue plaque in 2002, before moving to 56 Kempshott Rd, Streatham. His mother, Kate, died from acute peritonitis when he was 14, and his father lost his business 18 months later.
He married Eileen Guinness, with whom he had two sons and six daughters. His marriage disintegrated during World War II, and his oldest son George, an aviator, was killed in combat. His daughter Joan, who wrote a biography of her father, married the noted statistician George E. P. Box
