Dr Stephen Skinner is an expert in 15th and 16th-century manuscripts, having edited Dr John Dee’s Spiritual Diaries. He has written more than 40 books on Western esoteric traditions, as well as academic studies of medieval grimoires and Graeco-Egyptian papyri. His knowledge of the Voynich Manuscript period qualifies him to fill in the gaps in our knowledge of this amazing artefact. Dr Rafał T. Prinke is a historian and an assistant professor at Eugeniusz Piasecki University in Poznań, Poland. He recently published a 900-page book on alchemical writings from the earliest times until the end of the 18th century. He is also, along with Stephen Skinner, one of the contributors to the Watkins edition of The Voynich Manuscript. Dr Georgiana (Jo) Hedesan specializes in the history of alchemy, with a particular focus on medical alchemy, and the early modern movements of Paracelsianism and Helmontianism. Her first book, entitled An Alchemical Quest for Universal Knowledge: The ‘Christian Philosophy’ of Jan Baptist Van Helmont (1579-1644) was published in 2016 by Routledge. She has recently concluded a Wellcome Trust Research Postdoctoral Fellowship in Medical History and Humanities at the University of Oxford, researching the topic of universal medicine and radical prolongation of life in early modern alchemy. She acquired a PhD in History from the University of Exeter in 2012 with a dissertation on Flemish alchemist Jan Baptist Van Helmont (1579-1644). Georgiana is lecturing in two undergraduate history courses at Oxford and working as an editor to the Oxford’s Cabinet Digital Platform.
