Wolfgang Eberhardt completed his Ph.D. thesis at the University of Hamburg, Germany in 1978.  He came to work with me that same year as a postdoctoral fellow at the University of Pennsylvania.  He was promoted to a research assistant professor in 1980.  Wolfgang was responsible for the synchrotron radiation studies of the group at the Tantalus Synchrotron in Stoughton, Wisconsin.  The picture shows Wolfgang on our beam line at Tantalus.  Together we made many significant discoveries. Some of the most cited papers are:

“Angle-Resolved Photoemission Determination of the Band Structure and Multi-Electron Excitations in Ni,” W. Eberhardt and E. W. Plummer, Phys. Rev. B 21, 3245 (1980).

“The Bonding of H to Ni, Pd, and Pt Surfaces,” W. Eberhardt, F. Greuter, and E. W. Plummer, Phys. Rev. Lett. 46, 1085 (1981).

“Charge Transfer and Non-Rigid Band Effects in the Graphite Compound LiC6,” W. Eberhardt, I. T. McGovern, E. W. Plummer, and J. E. Fischer, Phys. Rev. Lett. 44, 200 (1980).

“The Adsorption of N2: Chemisorbed on Ni(110)/and Physisorbed on Pd(111),” K. Horn, J. DiNardo, W. Eberhardt, H. J. Freund, and E. W. Plummer, Surf. Sci. 118, 465 (1982).

“Auger Electron Ion Coincidence Studies in Soft X-Ray Induced Fragmentation of N2,” W. Eberhardt, E. W. Plummer, I. W. Lyo, R. Carr, and W. K. Ford, Phys. Rev. Lett. 58, 207 (1987).

In 1982, Eberhardt and I wrote the following review about angle-resolved photoemisson.

“Angle-Resolved Photoemission as a Tool for the Study of Surfaces,” E. W. Plummer and W. Eberhardt, Advances in Chemical Physics 49, ed. by I. Prigogine and S. A. Rice, John Wiley and Sons, New York, 1982, p. 533.

In 1981 Eberhardt accepted an associate physicist position in the Physics department at Brookhaven National Laboratory but moved the Exxon Research and Eng. Co in New Jersey in 1983. In 1990 we accepted the position as Director of the Institute for Electronic Properties at the IFF, KFA-Jülich, Germany, what a joint appointment at the University of Cologne. In 2001 he became the scientific director for BESSY and in 2009 the scientific director of the Helmholtz Zentrum Berlin and a professor at the Technical University of Berlin.
