Naomi Mary Margaret Mitchison, Baroness Mitchison 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.

John Scott Haldane was a British physician physiologist and philosopher famous for intrepid self-experimentation which led to many important discoveries about the human body and the nature of gases. He also experimented on his son, the celebrated and polymathic biologist J. B. S. Haldane, even when he was quite young. Haldane locked himself in sealed chambers breathing potentially lethal cocktails of gases while recording their effect on his mind and body.
