Naomi Mary Margaret Haldane entered the world on the 1st of November 1897 in Edinburgh. Her father was John Scott Haldane, a prominent physiologist who conducted dangerous experiments with gases and respiration.
Her findings appeared in a paper titled Reduplication in Mice published in 1915. This work represented the first demonstration of genetic linkage in mammals according to historical records.
The Corn King and the Spring Queen appeared in 1931 and is considered by some critics to be the prime 20th-century historical novel. Literary critic Geoffrey Sadler stated that on the basis of her early writings she was unquestionably one of the great historical novelists.
Naomi married Gilbert Richard Mitchison on the 11th of February 1916 while he was on leave from the Western Front. After several years they agreed to an open marriage in which they entered into other relationships conducted with dignity and humor.
She received the Commander of the Order of the British Empire honor in the 1985 New Year Honours list. In old age she expressed anxiety about nuclear arms misuse and stated that experiencing two world wars in one lifetime felt excessive.
