More than 90 individuals and organizations contributed to establish the David J. Ellis Endowed Chair in Antimicrobial Resistance and Large Animal Clinical Sciences to carry on the tradition of excellence in teaching, research, and service that Ellis established at MSU. Ellis was an exemplary role model for colleagues and students, as well as a trusted advisor to producers and clients. In his 30 years at MSU, he was the head of ambulatory veterinary medicine, head of the large animal veterinary clinic, head of the veterinary extension section, and chief of field investigation for the MSU Veterinary Diagnostic Laboratory (previously known as the Diagnostic Center for Population and Animal Health).

Dr. Pamela Ruegg is the first person to hold the endowed chair and leads the Antimicrobial Stewardship and Dairy Health Management Laboratory. As a student at the Michigan State University College of Veterinary Medicine, Dr. Ruegg fondly recalls being taught by Dr. Ellis, and was strongly influenced by his practical approach to serving animal agriculture.
