This episode is a bit different than previous, in that the first part is a review of the life and work of the famous cardiac surgeon Christiaan Barnard, who performed the world's first human heart transplant. The second part is an interview with cardiac surgeon Dr. David K. C. Cooper, who worked with Dr. Barnard, and wrote the definitive biography on him. We discuss Dr. Barnard, as well as the history of cardiac surgery, and even get into xenotransplantation! It was a pleasure to speak with him, and I hope you enjoy the interview as much as I did.
