Susan B. Edgington is a teaching and research fellow at Queen Mary University of London. She has written extensively on many aspects of the crusades, but it is her close familiarity with the Latin sources for the period in question, 1095-1118, that uniquely qualifies her to write this biography. She is the editor and translator of Albert of Aachen’s Historia Ierosolimitana (Oxford, 2007); translator (with Thomas S. Asbridge) of Walter the Chancellor’s The Antiochene Wars (Aldershot, 1999); (with Carol Sweetenham) of The Chanson d’Antioche (Farnham, 2011); and (with Steven Biddlecombe) of Badric of Bourgueil’s History of the Jerusalemites (Woodbridge, forthcoming). Her critical comparison of the relationship of Bartolf of Nangis’ Gesta Francorum Iherusalem expugnantium with the chronicle of Fulcher of Chartres (Crusades 13, 2014) will lead to a new edition and translation of this important source.
