My memory of Eric Stein is of a teacher and mentor rather than a colleague. I will leave to others more qualified than I to describe his major contributions to the academic literature and teaching of European Community and public international law. When I entered Michigan Law School as a student in 1980, Eric had "technically" retired or at least transitioned to emeritus status. I say he had "technically" retired because his commitment to the law school community as a writer, teacher, and mentor to students never appeared to diminish. He still taught a number of classes and seminars, wrote extensively, and was more than generous with the time he spent with young law students like myself who professed an interest in international law.
