The primary motive that has induced me, an internist, to accept the kind invitation to have a share in this special number of the Archives of Surgery is that by so doing I may show my appreciation of, and affection for, Dean Lewis. To have known him as a student, intern, faculty and hospital colleague and congenial companion is to have an abiding sense of his superior ability as a surgeon, teacher and medical leader, and of his genius for making and holding friends.
I trust it may not seem inappropriate to reiterate in this paper the truth that medicine and surgery are, and should be, closely related and mutually helpful, and, as a concrete illustration of the debt owed by medicine to surgery, to call attention to the worth while contributions made to the knowledge of heart disease, a little more than a century ago, by three British surgeons.
