While handling an artifact from the Museum’s collection, a familiar sight piqued my curiosity. Stamped onto a pin awarded by the Canadian Medical Association was a snake coiled around a staff. I had seen the same symbol on the badges of emergency health service workers, emblazoned on ambulances, and on pharmaceutical logos. I wondered, what were the origins this symbol? Why was it significant to medical organizations? Through what process had so many health professionals adopted it as a representation of their work?
