Mary Trevelyan (1881–1966) spent a lifetime committed to the promotion of internationalism and peaceful cooperation, especially between young people and students. All her life she remained deeply involved in charitable endeavours and her published works are two remarkable memoirs: From the Ends of the Earth and I’ll Walk Beside You: Letters from Belgium, September 1944–May 1945. From 1938 to 1957 she was a close friend and companion of T.S. Eliot, a period about which she wrote in her unpublished manuscript, The Pope of Russell Square.
