In 1885, the first successful key-driven calculator was invented by Dorr Eugene Felt. To save expanse in building the model of the device, called the "Comptometer," Felt purchased wooden macaroni boxes to be used to house the devices. Within the next two years, Felt sold eight of them to the New York Weather Bureau and the U.S. Treasury. The device was used primarily for accounting, but many of them were used by the U.S. Navy in engineering computations, and was probably the most popular accounting machine in the world at the time.
