Today, it is our honor to speak with Dr. Jacalyn (Jackie) Duffin, an inductee into the 2019 class of the Canadian Medical Hall of Fame. Dr. Duffin was recognized for being a staple in the field of Medical History. She has made significant contributions in our historical understanding of rural practices, diagnostic technology, pharmacology, disease concepts, and health policy. Further, she is known to have been a crucial component in the canonization of Marie-Margeurite d’Youville, after utilizing her knowledge in medicine and history to conclude a miracle! All of this, and more, on Multipotent MD!
