AUTHOR INFORMATION

SARAH L. VALLANCE received her B.Sc. (Hons) in applied chemistry from the University of Northumbria at Newcastle in 1992. After a period in industry as a method development analytical chemist, she returned to the University of Northumbria at Newcastle in 1994 to begin Ph.D. studies in collaboration with the Tate Gallery, London. Her research focused on development and application of gas and high performance liquid chromatographic methods for identification of artists' proteinaceous and natural gum binding media, ultimate aim of project being study of late-18th- and early-19th-century works by artists such as William Blake, J.M.W. Turner, and D. G. Rossetti. She was awarded her Ph.D. in 1997 on “The Development and Application of Chromatographic Techniques in the Characterization of Artists' Media.” She has published a number of papers on work in conservation science. Currently, she is the assistant web editor at the Royal Society of Chemistry, London, U.K. Address: Royal Society of Chemistry, Burlington House, Piccadilly, London W1V OBN, U.K.

BRIAN SINGER obtained his Ph.D. in the field of synthetic organic chemistry at the University of Leeds, U.K. A lectureship at Gateshead Technical College, where he taught chemistry on a diploma course in Fine Art Conservation, established an interest in conservation science. He is currently a senior lecturer at the University of Northumbria at Newcastle teaching chemistry in the M.A. Conservation of Fine Art course. His research interests include the investigation of artists' techniques and materials and the effects of certain conservation treatments on paper supports. Address: Department of Chemical and Life Sciences, University of Northumbria at Newcastle, Ellison Building, Ellison Place, Newcastle upon Tyne, Tyne and Wear NE1 8ST, U.K.

STEPHEN M. HITCHEN graduated from the University of Manchester Institute of Science and Technology (UMIST) in 1976, with a B.Sc. (Hons) in chemistry. He obtained his Ph.D. in synthetic organic chemistry from UMIST in 1980 and is currently a senior lecturer in the Department of Chemical and Life Sciences at the University of Northumbria at Newcastle. His current research interests include aided method development in chromatography. Address as for Singer.

JOYCE H. TOWNSEND received her B.Sc. (Hons) in physics from the University of Glasgow in 1979. She was a conservation scientist at Glasgow Museums, 1979–87, specializing in accelerated aging and materials testing for conservation. From 1987 to 1991, she was a conservation scientist, and from 1991 to the present, senior conservation scientist, at the Tate Gallery, London. She received her Ph.D. from the Courtauld Institute of Art, University of London, 1991, on “The materials and Techniques of JMW Turner, RA 1775–1851.” She concentrates on the identification and aging of artists' materials used in the later 18th and 19th centuries and also works with conservators who are evaluating or developing conservation processes. She has published studies on J.M.W. Turner, James Abbott McNeil Whistler, and Edgar Degas and is currently working on Sir Joshua Reynolds. She has been editor and technical editor of several conference proceedings, most recently Turner's Painting Techniques in Context (UKIC, 1995) and Resins: Ancient and Modern (SSCR 1995).
