Mr. Dorr Eugene Felt

Bio/Description
During the US Thanksgiving holidays of 1884 Dorr decided to build the prototype of a new calculating machine that he had invented. Because of his limited amount of money, he used a macaroni box for the outside box, and skewers, staples and rubber bands for the mechanism inside. It was finished soon after New Year's Day, 1885.
Felt brought his idea to Chicago businessman Robert Tarrant. They signed a partnership contract on November 28, 1887, and incorporated the Felt & Tarrant Manufacturing Company on January 25, 1889. Felt later went on to invent more devices and acquired 46 domestic patents and 25 foreign ones. The original macaroni box prototype and the first Comptograph ever sold are now part of the Smithsonian Museum collection of antique calculators.
