Pehr (Per) Georg Scheutz (23 September 1785 – 22 May 1873) was a Swedish lawyer, translator, and inventor, who is now best known for his pioneering work in computer technology.
He is most known for his inventions; the best known of these is the Scheutzian calculation engine, invented in 1837 and finalized in 1843. This machine, which he constructed with his son Edvard Scheutz, was based on Charles Babbage's difference engine. In 1851 they obtained funds from government to build an improved model, which was created in 1853 (was roughly the size of a piano), and subsequently demonstrated at the World's Fair in Paris, 1855. The machine was then sold in 1856 to the Dudley Observatory in Albany, New York.[1][2] In 1857 British government ordered another model, which was built by Donkin's company in 1859.[3][4]
The devices were used for creating logarithmic tables.
While the machine was not perfect and could not produce complete tables, Martin Wiberg reworked the construction from the ground up and in 1875 created a compact device which would print complete tables.
