In 2001, Harold Guetzkow reached out to Kent Kille, a scholar beginning his academic career, and subsequently helped inspire and support a project that culminated in the publication of the edited volume "The UN Secretary-General and Moral Authority: Ethics and Religion in International Leadership." This article recounts the project, which would turn out to be the final research engagement by Guetzkow at the end of a long and storied academic career, and presents impressions from the author of Guetzkow's ongoing search for knowledge, his supportive mentoring role, and his conscientious commitment to the place of ethics in global affairs.
