In 1950, with millions of clones manufactured, the Odhner arithmometer was one of the most popular type of mechanical calculator ever made. The number of machines produced increased constantly until the appearance of the electronic calculators in the early 1970s. For instance, the production of one

After Odhner's death, in 1905, his sons
Alexander and Georg and son-in-law Karl Siewert continued the production and about 23,000 calculators were made until the factory was nationalized during the Russian revolution and was forced to close down in 1918. This makes the Brunsviga arithmometer, with
