Murray Sidman lived a long life in which he gave so much to the field of behavior analysis, influenced so many students, and mentored so many behavior analysts around the world. Dr. Sidman had vital roles in the founding of JEAB and in planting the seeds of what have become incredible behavior analysis programs across the globe. A shining example of the result of his international efforts is the strong behavior analysis programs now in many Brazilian universities, where researchers keep vigorous lines of research initiated by him alive to this day. Dr. Sidman has influenced so many of us, personally, academically and professionally. This panel will highlight some of his many major contributions to the science of behavior analysis including single-subject methodology and experimental designs, coercion and its effects, avoidance behavior, stimulus control, errorless learning, programmed learning, and stimulus equivalence. In this memorial panel, we will also share some personal stories of how Dr. Sidman (or Murray to many of us) continued to teach us until his very last days. Murray was a kind and loving person, and he will be sorely missed. His lessons will continue to guide us in advancing behavior analysis and in creating a less coercive world.
