My Transplant Surgeon at University of Wisconsin Hospitals was Dr. Folkert O. Belzer. He was a really wonderful Transplant Doctor who engineered so much to do with transplantation. The write-up is on this link
and if you are interested in how transplants evolved, please read.
Dr. Belzer died at the age of 64 from colon cancer. What a great mind and such a loss.
He was the most gentle man and gave me such hope through some really difficult times.
