John Wallis (1618-1703) was a founder member of the Royal Society, a mathematician and pioneer of calculus, and a linguist whose work included the groundbreaking tract on phonetics, De Loquela (1653). David Cram is an Emeritus Fellow of Jesus College, formerly Senior Research Fellow and Lecturer in Linguistics. By background and training he is a theoretical linguist, but the bulk of his research has concerned the history of ideas about language in the seventeenth century, on topics ranging from philosophical languages to linguistic eschatology. He is co-editor, with Jaap Maat, of George Dalgarno on Universal Language: The Art of Signs (1661), The Deaf and Dumb Man's Tutor (1680), and the Unpublished Papers (OUP, 2001). Jaap Maat is Lecturer in Philosophy at the University of Amsterdam, and is a member of the Institute for Logic, Language and Computation (ILLC). He has published widely on the history of linguistic ideas and the history of logic. He is a founding editor of History of Humanities and co-editor, with David Cram, of George Dalgarno on Universal Language: The Art of Signs (1661), The Deaf and Dumb Man's Tutor (1680), and the Unpublished Papers (OUP, 2001).
The authors, David Cram and Jaap Maat, have done an excellent and thorough job in providing this text, not only for its historical value, but also for the theoretical issues touched on in teaching language to the deaf. * Marga Stander, LINGUIST List *
