When we first encountered this artifact in the collection, we asked ourselves what on earth it could be. The name implies that it was “medical” in nature. Patent dates indicated that it was manufactured sometime after 1919 and the overall style and materials suggested not too long after that patent date. This gadget is a “violet ray” medical appliance, once advertised to cure a multitude of ills by applying a high voltage, high frequency, low current to the human body, and by producing ozone for direct inhalation. These devices were designed to be used in medical settings and at home by the consumer.
