from 1920 until the 1980s. This is one of three versions of the Addiator in the
Smithsonian collections. It was given to the Museum by the machinist and museum
specialist George A. Norton, Jr. Norton used the device to do routine addition,
subtraction, and multiplication until he acquired an electronic calculator.
