The Faculty History Project documents faculty members who have been associated with the University of Michigan since 1837. Key in this effort is to celebrate the intellectual life of the University. This Faculty History Website is intended as a component of the effort to document the extraordinary academic achievements of Michigan’s faculty in building and sustaining one of the world’s great universities. It provides access to a comprehensive database of information concerning the thousands of faculty members who have served the University of Michigan.

The Bentley Historical Library serves as the official archives for the University.


David Noel Williams
Regents' Proceedings 20

David N. Williams, Ph.D., professor of physics in the College of Literature, Science, and the Arts, retired from active faculty status on May 31, 1999.

Professor Williams received his B. A. degree in physics and philosophy in 1956 from Maryville College and his Ph.D. degree in 1964 from the University of California at Berkeley. He moved on to postdoctoral studies at the Eidgenossiche Technische Hochschule in Zurich, the Centre d’Etudes Nucleaires, in Saclay, France, and the Institute for Advanced Study in Princeton. He joined the University of Michigan as an assistant professor in 1980. He served on various departmental committees and was a graduate advisor from 1985-95.

His research interest have generally been in quantum field theory, with a mathematical physics orientation. In the earliest part of his career, he did important work on invariant scattering amplitudes free of kinematic singularities. He was a major author of the proof of Stapp’s Theorem on Lorentz covariant holomorphic functions. Later, her published work on the mathematical theory of unstable particles and Euclidean quantum field theory. In recent years, he has been interested in the triviality problem for quantum field theory. He has also focused recently on the development of software for algebraic manipulation, related to M. Veltman’s Schoonschip program. He plans to remain active in these areas for the next few years.

The Regents now salute this faculty member by naming David N. Williams professor emeritus of physics.
