Per Georg Scheutz (1785–1873) and Edvard Scheutz (1821–1881) were a Swedish father-and-son duo that achieved what Charles Babbage could not: a commercially produced Difference Engine. Inspired by Babbage’s designs in a 1834 magazine review, Per Georg handled the conceptual vision while Edvard provided the technical skill.
They simplified Babbage’s complex mechanisms to create their “Scheutzian Calculation Engine”, which won a Gold Medal at the 1855 Paris Exhibition and was bought by the British government and then eventually sold to the Dudley Observatory in New York.
