notes: label: Description
content: The Siemens electrodynamometer was developed by the German physicist, Werner von Siemens, in 1880, and designed for measuring either direct or alternating electric current. The form was widely used until the 1920s when it was replaced by the more convenient direct reading meter patented by Edward Weston. An inscription on this example reads “Queen & Co. Makers Phila.”
