Martin Wiberg

Martin Wiberg ( September 4, 1826 in Viby, † December 29, 1905 in Stockholm) was a Swedish inventor and designer of calculating machines.

Wiberg studied from 1845 at Lund University, where he studied medicine, but turned to the sciences for financial reasons in 1850 and received his MA ( filosofie magister ).

Inspired by the Difference Engine by Georg Scheutz and Edvard Scheutz 1875 he built a separate, more compact machine, the calculated logarithm tables and printed. The tables published in Swedish, English, French and German. He presented to the French Academy of Sciences. She is now at the Technical Museum in Stockholm. For the construction he had the support of some influential personalities, including the future King Oscar II, he was awarded a prize by the Swedish government and some prices.

Commercially, however, he had no success with his calculating machine or printed by their logarithms - the latter partly because of poor printing quality.

He wrote several other inventions, but also commercially had no great success. He was also not a good businessman. For example, he invented heaters and speed controllers for trains, torpedoes, devices with which plants and animals could be collected from the sea floor, a device for the production of matchboxes, a coffee Extrahierungsapparat and a separator for liquids of different density and a rifle automatic. In 1896 he received a patent for a " spectroscopic " could be served at the keyboard with a different colored light beams.

Some of his inventions were presented at the Swedish part of the World Expo 1876.
