Jonathan R. Topham is a Senior Lecturer in History of Science at the University of Leeds, UK. Among his co-publications are Science in the Nineteenth-Century Periodical: Reading the Magazine of Nature (Cambridge University Press, 2004), Science in the Nineteenth-Century Periodical: An Electronic Index (HRI Online, 2005), Culture and Science in the Nineteenth-Century Media (Ashgate, 2004), and two volumes of the Correspondence of Charles Darwin (CUP, 1985-). His research relates mainly to the cultural history of science in early nineteenth-century Britain, and to the history of the life and earth sciences. He has published extensively on science and religion in early nineteenth-century Britain-more especially on natural theology and theologies of nature-and intends to complete a monograph on the Bridgewater Treatises shortly. He has also helped to pioneer a new approach to the subject of science and its publics, drawing particularly on the historiography of the book, and is currently preparing a book-length study of science and print culture in Britain, 1789-1832.
