Francis Cutler Ellis, an engineer in Chicago, devised the Ellis Micro-Dynameter in the early 1930s. This device, it was said, would “make the human body function as a simple electrical cell and measure the current it generates.” And it could diagnose virtually every human ailment. It was marketed by Ellis Research Laboratories, in Chicago, and endorsed by prominent chiropractors. It was widely accepted by chiropractors for diagnosing “subluxations” and became their main bioelectrical instrument. This example, a Model SA-1, was seized by the FDA.
