Electrical Component Associated with Herman Hollerith


This metal component includes a wooden framework painted black. An interrupter is at one end, and an electromagnet within the box. Herman Hollerith was the first inventor to build successful computing devices based on electromagnets. This may have been a part of a tabulating machine.

This piece does not seem to match any drawing in Hollerith’s patents.
