William St Clair (1937–2021) worked as a civil servant in the Treasury for many years before proceeding to Fellowships at All Souls, Oxford, then Trinity College, Cambridge, and finally the Institute of English Studies at the School of Advanced Study, University of London. His passion for history motivated him to publish Lord Elgin and the Marbles in 1967, a pioneering study of the controversial acquisition of the Parthenon Marbles. In the book’s third edition (1998), St Clair exposed how attempts to whiten the Greek relics by the British Museum led to their damage. Equally invested in the world of literature, St Clair published books and articles on the genre of British biography, on writers of the Romantic period, most notably Byron, and in his massive study, The Reading Nation, on the history of books. He was elected a Fellow of the British Academy in 1992. His belief in open-access publishing led him to co-found Open Book Publishers in 2008; he acted as its Chairman until his death.
