The Odhner was made by Willgodt T. Odhner of St.Petersburg, based on his invention from 1874. Large-scale manufacture did not commence until 1886 when the W.T.Odhner factory was built. During the late revolution the factory in St.Petersburg became the property of the state, the equipment was moved to Moscow, and soon the manufacture was entirely discontinued. However, Odhner's legal successors went to Sweden where they founded the Aktiebolaget Original Odhner in Göteborg and resumed the manufacture of the Original Odhner.
Odhner in Russia and Baldwin in the US patented their machines based on a similar mechanical principle: pinwheel machine (see Martin, page 12). Many machines that you will see on this web site are so-called Odhner type machines. In 1907, to differ own production from other Odhner type machines, the name was changed to Original Odhner.
