Mary Trevelyan (1881-1966) was heavily involved in charitable works and an influential commentator on British culture and society, perhaps best known for single-mindedly bringing about the establishment of International Students House in Regent's Park, London, the charity for which she was Warden for much of her working life. From 1938 to 1957 she was a close friend and companion of T.S. Eliot, a period which she wrote of in the form of an unpublished manuscript titled The Pope of Russell Square.
