In 1893 the "Millionaire" mechanical calculator, about the size of a
small desk top, was introduced in Switzerland. The "Millionaire" was
the first commercially successful calculator that could perform
multiplication directly, rather than by repeated addition. It was
designed by Otto Steiger, a Swiss engineer and was first patented in
Germany in 1892. Patents were issued in France, Switzerland, Canada
and the USA in 1893. Production by Hans W. Egli of Zurich started
in 1893, and continued to 1935. Most models were driven by hand-crank
but some were electrified.
Roughly 4000-5000 Millionaires were sold.
