content: Ari Davis (ca. 1811-1855) was a skilled American craftsman who received two patents in 1854. #10,788 (of April 18) described a machine for producing wooden boxes with metal-reinforced dovetail corners. #11,415 (of August 1) described a magneto-electric machine. While this second patent was still in process, Davis sold the rights to both patents to Walter Kidder, a physician in Lowell, Massachusetts, allegedly for $4000. Advertisements for DAVIS’ (later DAVIS & KIDDER’S) PATENT MAGNETO-ELECTRIC MACHINE, FOR NERVOUS DISEASES were soon to be seen, with testimonials from three Americans involved with science: Benjamin Silliman at Yale College, Charles G. Page in Washington, D.C., and James R. Chilton, an instrument dealer in New York City. These machines were “MANUFACTURED BY W. KIDDER, Sole Proprietor, whose signature is attached to all genuine Machines.” By 1857, the business was in the hands of William H. Burnap (b. 1825), also of Lowell. By 1865, Burnap was working in New York City, and advertising as “Manufacturer of Davis & Kidder’s Electric Machines.”
