It follows the history of "information machines" from Charles Babbage's Difference Engine through Herman Hollerith's Tabulating Machines to the invention of the modern electronic digital computer.
It counted among its collections the unfinished prototype of the Difference Engine No. 1, designed by Charles Babbage, considered a "father of the computer".
In 1855, Per Georg Scheutz completed a working difference engine based on Babbage's design.
In 1855, Georg Scheutz became the first of a handful of designers to succeed at building a smaller and simpler model of his difference engine.
