An Arithmometer made by Thomas de Colmar has sold at the top of Auction Team Breker's Science & Technology, Fine Toys and Automata sale, held on November 16 in Germany.
The richly decorated deluxe model of the early calculator sold for an impressive $256,403, 374.8% above the $54,000 high estimate.
The Arithmometer was the first mechanical calculator capable of everyday use in offices. Patented by Thomas de Colmar in 1820, it performs long multiplication and division, as well as addition and subtraction.
The example at auction is a special presentation model that was given to "Mademoiselle E Renaud" as a "Souvenir by the inventor". According to the auction house, Renaud was married to Louis Thomas, brother of Thomas de Colmar, and therefore this piece comes straight from the inventor's family.
Further highlights of the sale include a German Enigma cipher machine from 1944, which sold comfortably within estimate at $43,183. Complete with three rotors, corresponding serial numbers, 28 original flat lamps and with its original wooden case with a swastika symbol, it remains in working condition.
