Calculating Machines and Instruments
DescriptionThis machine is set on a four-legged metallic stand, two of which are terminated by wheels. On each side of the stand is a folding panel made of wood. This model of the Millionaire was put in an aluminum box with a black-painted sheet-metal cover hinged at the back. The brass top panel of the machine was finished with a chemical blackening agent.
On the top panel is a multiplier lever, a hand crank, eight rows of sliding markers with numbers from 0 to 9, a regulator to set which type of operation is done (A, M, D, S), a carriage shifter and two sliding carriage buttons that set the result numbers and the control numbers to zero.
Inside the cover are instructions in English on how the Millionaire worked. There is also a multiplication table from 0-99 with two sliders, called a dividing schedule. Two safety screws were used to secure parts of the mechanism in place when the machine was moved. The brush is missing.

FunctionInvented by the Swiss engineer Otto Steiger (1858-1923), the "Millionaire" calculating machine was invented to make the four simple arithmetical operations: addition, subtraction, multiplication and division. Such mechanical devices go back to the seventeenth century, with the famous inventions of Pascal and Leibniz. This one here was the first machine commercially sold that was able to make direct multiplications, that is without having to make repeated additions, as did earlier machines.
Over 4000 Millionaire machines were built between the 1890s and the 1930s. This one has serial number 704. It was manufactured and marketed by the Hans Egli Company of Zurich and sold in the United States via the New York City firm W. A. Morschhauser.
The Millionaire calculator can be used to perform all fundamental arithmetic operations: addition, multiplication, subtraction, and division.
Unlike many other calculators of its era, the Millionaire calculator performs multiplication and division directly instead of in a series of additions and subtractions.
In order to perform an operation, the machine has to be cleared of all values and the carriage set in its rightmost position. The user then selects the operation she would like to perform using the knob at the top right-hand side of the control panel. Each operation proceeds using a combination of number inputs, and turning the crank in the most top right-hand corner of the control panel. For a detailed explanation of how to perform each operation see here.
