In this panel discussion, we will show some highlights of the video record of a retirement celebration for Donald M. Baer, an eminent professor and scholar in behavioral science and a founder of applied behavior analysis. Four distinguished behavior analysts from Australia and New Zealand who were students and colleagues of Baer will serve as panelists to discuss the video and their recollections of working with Baer. In April of 2002, colleagues and friends of Baer gathered at the University of Kansas in Lawrence. Over 100 participants from around the world celebrated in anticipation of Baers retirement. The retirement festivities included both scholarly and social agendas. The scholarship took the form of a research seminar with invited speakers, followed by interactive discussions in which Baer served as impromptu discussant. The seminar was followed by a banquet and an evening of commentaries by many of Baers friends and colleagues, in a joyful tribute of respect, love, and good humor. Baers untimely death only two weeks after the retirement celebration placed the events in an entirely new context. The video record provides young behavior analysts around the world a glimpse of an intellectual leader of applied behavior analysis.
