Distinguished Professor Don Chalmers retired from the Law Faculty at the University of Tasmania on Friday 10 July 2020. This article is dedicated to Don, providing a brief account and acknowledgment of his fine contributions to legal research and education and law reform, particularly in the field of health and medical law, research ethics and policy reform. He has been an excellent colleague, mentor, leader, teacher, and researcher. He deserves to enjoy a long and rewarding retirement, though we, and many others, will not allow him to slip entirely out of the limelight. Don is still much needed, and still has so much to give in our ongoing quest to ensure that legal, research ethics and policy responses are adequate in reaping the benefits and responding to the challenges of biomedical advances.
