Felt & Tarrant Comptometer, 1951
01
Artifact Overview
Mechanical adding machines like this Comptometer were indispensable--and almost indestructible--office equipment until the computer era. Dorr Felt's 1884 invention of a key-driven mechanical adding machine had become big business by the 1950s, when this Comptometer was made. This particular Comptometer was used in the accounting department of an eyewear manufacturing company from 1951-1967, when its operator retired.

Thomas Edison's electric pen, an ancestor of both the mimeograph and the tattoo needle, was a successful product in the mid-1870s. Users would write normally with the pen, which, instead of a nib, had a needle powered by an electric motor. The needle poked holes into a stencil, which was then used to copy the document. Many businesses found document duplication an attractive possibility.
