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.
