Ellis Micro-Dynameter Model SA-1
notes: label: Description
content: Invented by an electrical engineer named Francis Cutler Ellis (1890-1957), the Ellis Micro-Dynameter promised to make the human body “function as a simple electrical cell and measure the current it generates” and also diagnose almost every human ailment. Distribution began in 1931, and it was soon widely accepted by chiropractors for diagnosing “subluxations” and became their main “bioelectrical instrument.” In the 1950s, the FDA estimated that about 5,000 had been sold. The device was manufactured in Chicago, and available in several models. In the 1960s, the FDA obtained an injunction banning interstate distribution of Micro-Dynameters and had them removed from many chiropractic offices.
