In memoriam of Dr. David White, PhD, FR CPath (1946–2017)

David White was my long-time friend and colleague. Our friendship began just before the cyclosporine era when I was in Cambridge learning transplant surgery from Prof. Roy Calne. David was investigating experimental approaches to preventing rejection in Sir Roy’s department when Sir Roy showed first in the laboratory and then in patients the effectiveness of cyclosporine in controlling rejection. David was Sir Roy’s closest collaborator in those pivotal studies that transformed transplantation into one of the greatest achievements of modern medicine
