Pierre Klein has been a professor of international law at the Université libre de Bruxelles (ULB) for nearly twenty-five years. Together with his colleague Olivier Corten, they have published some twenty books and nearly 250 articles. Under Olivier's direction, the ULB Center for International Law launched a large project in 2013 to decompartmentalize academic and popular/cultural approaches to international law. Their comic book is an extension of this initiative.
