Register of Millionaire Calculators


The Millionaire Calculating Machine was manufactured by H.W.Egli in Switzerland from 1893 to about 1933. A letter from the company (dated November 1967) states: "More than 5000 machines "The Millionaire" have left our works."

This page is a register of Millionaire calculators that are known to still exist in public or private collections, both within Australia and around the world.

If you own a Millionaire, or know of one that is not listed here, I would be grateful if you could forward the basic details (as below) via the Enquiry Form for inclusion in this register.


The "Model" codes below are made up from four characters:

A fifth character D (when present) indicates a dual-register machine.
Serial numbers in bold are links to photographs of the machines.

The statistics page gives a preliminary analysis of the distribution the machines. If you require more detailed or up-to-date analysis, you are welcome to cut-and-paste the table following into a spreadsheet program and sort it in any way you wish.
