Françoise Viénot

Trained as a physicist, Professor Francoise Vienot was introduced to the mysteries of colour science by Yves Le Grand and she has carried forward his distinguished tradition. Her early work was on colorimetry: she was especially concerned with individual differences in colour matches, before the topic had become as fashionable as it later became. Her mastery of colorimetry led her to the work for which she is best known in the wider world: she developed an algorithm for simulating for the normal eye the appearance of scenes for the dichromat. This algorithm has found many practical applications, including an application for the iPhone that allows the user in real time to inspect the world as it appears to a protanope or deuteranope. Professor Vienot has contributed to many other aspects of colour science. She has published historical research on the colour system of Chevreul. She has published a textbook on colour science, as well as important papers on Maxwell's spot and macular pigment, on mesopic photometry, on the perception of gloss, and on the Benham-Fechner colours. She has a talent to take applied problems and use them to inspire fundamental research. For most of her career, Francoise Vienot has been based at the Museum National d'Histoire Naturelle; and this has had interesting influences on her science. She is an expert on plant pigments and is an authority on horticultural colours. The Museum brought her into contact with ecologists, a collaboration that led to the first experimental paper on the fruit signals that trees present to their disseminators. For nearly 20 years, she has marshalled all her considerable tact, patience and precision to bring to its conclusion CIE Technical Committee 1-36, which has prepared a physiologically based system of colorimetry. To our own Society, and to the IRGCVD from which it evolved, she has been an active and loyal contributor since 1974.              


Jack Werner

Professor Werner received his Ph.D. from Brown University under the supervision of Professor Billy Wooten in the Walter S. Hunter Laboratory of Psychology. He conducted postdoctoral research with Professor Jan Walraven at the Institute for Perception - TNO in Soesterberg, The Netherlands. He was a member of the Psychology faculty at the University of Colorado, Boulder and is presently a Distinguished Professor of Ophthalmology at the University of California Davis where also holds appointments in Vision Science, and Neurobiology, Physiology & Behavior.

An active member of ICVS and of it predecessor, IRGCVD, he is also a fellow of the American Association for the Advancement of Science, American Psychological Association, American Psychological Society, Association for Research in Vision and Ophthalmology, the Gerontological Society of America and the Optical Society of America. He received the Pisart Vision Award from Lighthouse International and he presented the University of Colorado, Boulder distinguished research lecture and the Optical Society of America Robert M. Boynton lecture.

He has made important contributions to our knowledge of the development and aging of color mechanisms using psychophysics, VEP's and most recently optical imaging techniques, OCT and adaptive optics. He has contributed to our understanding of the processes of aging in perception particularly as they relate to plasticity and potential clinical applications. Throughout his career he has maintained an active interest in opponent color mechanisms, color in art and color illusions.

A generation of vision scientists has enjoyed the benefits of reading the many books he has coedited. These include, Visual Perception: The Neurophysiological Foundations, Color Vision: Perspectives from Different Disciplines, The Visual Neurosciences , and The New Visual Neurosciences, which like Professor Werner's own research have brought together discoveries from anatomy, physiology and psychophysics to illuminate fundamental mechanisms underlying human perception.              


David Foster

Prof. Foster’s distinguished career epitomizes the multidisciplinary nature of vision research. It began at Imperial College, London where he studied physics and went on to do a Ph.D. in vision with W. D. Wright in the Applied Optics Section. He subsequently held posts at Imperial College (Department of Physics), Keele University (Department of Communication and Neuroscience), Aston University (Department of Vision Sciences), and the University of Manchester (initially in the Institute of Science and Technology, Department of Optometry and Neuroscience). He is currently Professor of Vision Systems and Director of Research in the School of Electrical and Electronic Engineering at the University of Manchester.He is a fellow of the Institute of Physics and the Optical Society of America.

Prof. Foster’s research has advanced our understanding of colour vision for over 35 years. His studies of colour constancy report landmark discoveries. The breadth of his contributions includes work on rod-cone interactions, colour vision deficiency, colour perception of natural scenes and hyperspectral imaging. In addition to his own research, he has tirelessly nurtured the entire field of visual science, most notably as a co-founder and longtime editor-in-chief of Spatial Vision and as an editor, senior editor and since 2013 the editor-in-chief of Vision Research.
