| Baldwin
Calculator 1902 Model |
 |
| "Invention of Frank S.
Baldwin, of Newark, who has been engaged in the construction of similar machines for over
twenty-five years, his first being the pioneer in single cylinder machines, and which was
awarded the Scott medal by the Franklin Institute of Philadelphia in 1874. It was during
that year that Mr. Baldwin took out letters patent for a Calculating Machine, but not
being satisfied with it, he never placed it on the market. The present Calculator, patented in 1902, is the result of years of patient study and labor, and is fairly clamed to be the simplest, most compact and accurate Calculating Machine yet offered to the public."
