ROCHESTER, N.Y., May 23, 2001-- Xerox Corporation's (NYSE: XRX) Charles B. Duke has been elected to The National Academy of Sciences, an organization chartered by Congress to enlist the nation's top scientists and engineers in service to the country. The Academy, which covers disciplines from anthropology to mathematics, this month chose 72 new members "in recognition of their distinguished and continuing achievements in original research." Duke, a physicist and vice president and senior research fellow in Xerox's Wilson Center for Research and Technology, was one of only three new members elected from private industry. He was recognized for furthering the understanding of the nature of surfaces and the interfaces between materials. His work on electron-solid interaction was instrumental in the evolution of surface science as a quantitative discipline. The Academy cited "his pioneering contributions to electron tunneling, surface science, and organic solids, which have profoundly influenced these fields, particularly his work on resonant tunneling, electron and positron solid scattering, semiconductor surface structure, and the electronic properties of organic solids, especially polymers." "This well-deserved election to the Academy recognizes Charlie Duke's extraordinarily distinguished and productive work as a scientist, active participant in professional societies and manager of technology," said Herv/ Gallaire, senior vice president, Xerox Research and Technology. Duke is only the second scientist in the company's history to be elected to the Academy while an active Xerox employee. At Xerox, his theoretical work influenced the design rules for a new class of polymer-based photoconductors and dry inks that resulted in the introduction of the first flexible-belt photoreceptors. This technology, which was vital for Xerox's commercial success in the 1980s and 1990s, has been at the core of all Xerox copier products since the early 1980s. In 1993, he was elected to the National Academy of Engineering for this work. Beyond his corporate responsibilities, Duke has published more than 370 technical publications, including three books, and has been involved in supporting and leading several professional societies. He is a Fellow of the American Vacuum Society, the American Physical Society and the IEEE, and a life member of Sigma Xi. Since 1992, he has been editor of the scientific journal Surface Science, and he has served on the boards of editors of 11 scientific journals and advisory boards of 12 university and government organizations. Duke joined Xerox in 1972. He received a bachelor's degree in mathematics from Duke University in 1959 and a doctorate from Princeton University in 1963. The National Academy of Sciences is a private organization of scientists and engineers established by Congress in 1863. It has 1,874 active members representing 31 scientific disciplines. Only 182 are physicists.
