WIRSUNG,JOHANN,GEORG (1589-1643) AND THE PANCREATIC DUCT - THE PROSECTOR OF PADUA, ITALY

Although his primacy was subsequently challenged by a student, it is n ow known that Johann Georg Wirsung, the prosector of Padua, Italy, dis covered the human pancreatic duct in 1642 during the dissection of an executed murderer. Instead of publishing his discovery, he engraved a drawing of the duct on a copper plate, from which he made seven or mor e imprints. The copies were sent to leading anatomists of Europe with the question, ''Should I call it an artery or a vein! I never found bl ood in it....'' Three and a half centuries later, the copper plate rem ains well preserved and the authors, to the surprise of European surge ons and librarians, but with their aid, have traced six copies of the ''ductus Wirsungianus'' imprints still in existence. This is the story of Wirsung the man, his subsequent assassination, and finally the rec ognition that his finding had opened a new field of science.
