Donald W. Seldin, M.D., is widely revered as one of the greatest chairs of Internal Medicine in American medical history. He served in that role for nearly four decades, transforming a handful of dilapidated army barracks into one of the leading medical centers in the world – host to Nobel Laureates and members of the national academies. He has trained literally thousands of medical students and residents, and many of his former students now occupy high academic medical positions across the country. Dr. Seldin is considered the intellectual father of UT Southwestern Medical School.
