Gerhard Jäger is a Professor of Logic and Theoretical Computer Science at the University of Bern. He received his PhD from the University of Munich in 1980. From 1979 to 1986, he was engaged in postdoctoral work at the Universities of Oxford, Munich and Stanford, as well as the ETH Zurich. From 1986 to 1988, he was an Assistant Professor of Computer Science at the ETH Zurich. In 1988, he joined the Faculty of Natural Sciences of the University of Bern, first as an Associate Professor of Computer Science, and since 1992, as a Full Professor of Logic and Theoretical Computer Science. He served as the Dean of this faculty from 2002 to 2004 and as member of the Research Council of the Swiss National Science Foundation from 2004 to 2012. His internationally well established research focuses on mathematical logic, in particular proof theory, and the logical aspects of computer science.Wilfried Sieg is Patrick Suppes Professor of Philosophy at Carnegie Mellon University, USA.

Koellner's contribution stands in contrast to Parsons's paper which provides an excellent exposition of Feferman's philosophy from a neutral perspective. ... This volume is an extraordinary tribute to the person Solomon Feferman and his work. It contains material which should inspire future generations to pursue his ideas, be it on the technical side or on the philosophical side."
