Naomi Mary Margaret Mitchison, Baroness Mitchison (; 1 November 1897 – 11 January 1999) was a Scottish novelist and poet. Often called a doyenne of Scottish literature, she wrote over 90 books of historical and science fiction, travel writing and autobiography. Her husband Dick Mitchison's life peerage in 1964 entitled her to call herself Lady Mitchison, but she never did. Her 1931 work, The Corn King and the Spring Queen, is seen by some as the prime 20th-century historical novel. Childhood and family background Naomi Mary Margaret Haldane was born in Edinburgh, the daughter and younger child of the physiologist John Scott Haldane and his wife (Louisa) Kathleen Trotter. Naomi's parents came from different political backgrounds, her father being a Liberal and her mother from a Conservative, pro-imperialist family. However, both were of landed stock; the Haldane family had been feudal barons of Gleneagles since the 13th century. Today the best-known member of the family is probably Naomi's elder brother, the biologist J. B. S. Haldane (1892–1964), but in her youth her paternal uncle Richard Burdon Haldane, 1st Viscount Haldane, twice Lord Chancellor (from 1912 to 1915 under H. H. Asquith, and in 1924 during the first Labour government of Ramsay MacDonald), was better known. Naomi followed her brother to the Oxford Preparatory School (later Dragon School) in 1904–1911, as the only girl there. From 1911, she was tutored at home by a governess. She qualified for the University of Oxford in 1914, via the Oxford higher local examination and entered the Society of Oxford Home Students (later St Anne's College) to pursue a degree course in science. However, she chose before completing the course to become a nurse, as the First World War had broken out. After a course in first aid and home nursing in 1915, she joined a Voluntary Aid Detachment at St Thomas's Hospital, London. Her service was much curtailed after she caught scarlet fever. The Haldanes were known for their self-styled domestic experiments. She and her brother John started investigating Mendelian genetics in 1908. They initially used guinea pigs as experimental models, but changed to mice as they were more convenient to handle. Their findings were published as "Reduplication in Mice" in 1915. This was in fact the first demonstration of genetic linkage in mammals. Early career Like her father John Scott Haldane and elder brother J. B. S. Haldane, Naomi Haldane initially pursued a
