American surgeon
(September 29, 1935 - September 20, 2018) was a Distinguished Professor of Surgery, Division of Cardiothoracic Surgery, at the . His research interests initially centered in the area of myocardial protection and led to the introduction of blood , which is currently used by over 85% of surgeons in the United States and 75% of surgeons worldwide for adult and pediatric heart operations. He was a member of multiple surgical societies, including the , , and the .
