John T. Young received an MA in Translation Studies from Warwick University in 1990 and a PhD in History from Sheffield University in 1996. While studying for the latter, he transcribed almost all the German material in the archive of Samuel Hartlib for The Hartlib Papers on CD-ROM (Ann Arbor, 1995; second edition HROnline, Sheffield, 2002). His thesis was reworked into book form as Faith, Medical Alchemy and Natural Philosophy: Johann Moriaen, Reformed Intelligencer, and the Hartlib Circle (Aldershot: Ashgate, 1998), and he is co-editor and co-translator (with William Hitchens and Adam Matuszewski) of The Letters of Jan Jonston to Samuel Hartlib, transcribed and translated into English and Polish with an introduction, notes and bibliography (Warsaw: Retro-Art, 2000).
After some years working as a transcriber and encoder with the John Foxe Project in Sheffield, Young became Transcription and Tagging Manager of the Newton Project in 2000. In this role, he was co-author (with Rob Iliffe and Peter Spargo) of the online catalogue of Isaac Newton's theological, alchemical and personal papers, and either transcribed or oversaw the transcription of nearly four million words (for the most part previously unpublished) of Newton's corpus.
He also worked as research assistant, proofreader and indexer for Blair Worden on the posthumous publication of Hugh Trevor-Roper’s unfinished Europe’s Physician: the various life of Sir Theodore de Mayerne (New Haven and London: Yale University Press, 2006). He has published a number of scholarly articles and contributed to various biographical dictionaries including the Oxford Dictionary of National Biography and the Literary Encyclopedia.
As of March 2010, he is research associate with the Casebooks Project, helping to produce an online edition of the astrological-medical casebooks of Simon Forman and Richard Napier, while retaining a consultancy role on the Newton Project.
