Reinhard Kahle is Carl Friedrich von Weizsäcker Professor of Philosophy and History of Science at the University of Tübingen. Previously he held professorships in Mathematics at the University of Coimbra and at the Universidade Nova in Lisbon, finally becoming full professor in Mathematical Logic. He is a fellow of the Académie Internationale de Philosophie des Sciences. His main research interests are in proof theory and the history and philosophy of modern mathematical logic, in particular, of the Hilbert School. He has (co-)edited more than ten books and special issues such as, for instance, Gentzen's Centenary: The quest for consistency (Springer, 2015) and The Legacy of Kurt Schütte (Springer, 2020), both together with Michael Rathjen.

Giovanni Sommaruga studied philosophy and philosophical and mathematical logic at the University of Freiburg (Switzerland), Stanford University and the University of Siena. In 1996 he became assistant professor in logic and philosophy of science at the Albert Ludwig University Freiburg (Germany), and since 2008 he has been a senior scientist in the philosophy of the formal sciences (logic, mathematics, theoretical computer science) at ETH Zurich. His main research interests are in the philosophy and foundations of mathematics, the history of mathematical logic, and more recently the history of computability and information in theoretical computer science, and related philosophical issues.
