Katharine Marjory Stewart-Murray, Duchess of Atholl, DBE (née Ramsay; 6 November 1874 – 21 October 1960), known as the Marchioness of Tullibardine from 1899 to 1917, was a British noblewoman and Scottish Unionist Party politician whose views were often unpopular in her party.
Naomi Mary Margaret Mitchison, Baroness Mitchison (née Haldane; 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.
John Henry Mackay (February 6, 1864 – May 16, 1933) was a Scottish-German egoist anarchist, thinker and writer. Born in Scotland and raised in Germany, Mackay was the author of Die Anarchisten (The Anarchists, 1891) and Der Freiheitsucher (The Searcher for Freedom, 1921).
Later in life, under the pseudonym Sagitta, he became an advocate for homosexual love between men and boys.
John Anderson (1 November 1893 – 6 July 1962) was a Scottish philosopher who occupied the post of Challis Professor of Philosophy at Sydney University from 1927 to 1958. He founded the empirical brand of philosophy known as Australian realism.
Anderson's promotion of 'freethought' in all subjects, including politics and morality, was controversial and brought him into constant conflict with the august senate of the university. However, he is credited with educating a generation of influential 'Andersonian' thinkers and activists—some of whom helped to place Sydney in the forefront of the 'sexual revolution' of the 1950s and 1960s.
To Anderson, an acceptable philosophy must have significant 'sweep' and be capable of challenging and moulding ideas in every aspect of intellect and society.
