On September 29, 2023, the Penn Economic History Forum held a symposium on my new book, The Corporation and the Twentieth Century. The event was well attended, with commentators, both in-person and online, including Brian Cheffins (Cambridge University), Alexander Field (Santa Clara University), Patrick Fridenson (Ecole des Hautes Etudes en Sciences Sociales), Naomi Lamoreaux (Yale and Michigan), and Laura Phillips Sawyer (Georgia). I am grateful to my friend Dan Raff for organizing the event.
