In 1937, Duff and Diana Cooper commissioned their friend Rex Whistler to design a bookplate. Diana is shown as her goddess namesake. Duff’s red parliamentary boxes and documents show his working life, while the twining grapevines and champagne bottles speak of his love of wine and company
After Duff’s death in 1954, a group of his friends formed a Trust – the Duff Cooper Memorial Fund – to endow a literary prize in his memory. Two of the five judges appointed by the Trust are ex-officio: the Warden of New College and a member of Duff Cooper’s family – originally Duff Cooper’s son, John Julius Norwich. He ran the prize for its first 33 years, and then passed it on to his daughter, Artemis.
The other judges serve for five years and appoint their own successors. The first were Maurice Bowra, Cyril Connolly and Raymond Mortimer. Those serving at present are the author and editor Mark Amory; Susan Brigden FBA, historian and retired Fellow and Tutor of Lincoln College, Oxford: and David Horspool, History editor at the Times Literary Supplement.
