Experimental models and moulds from Charles Babbage's work on calculating machines. Charles Babbage (1791-1871) was a British computing pioneer who first conceived the idea of an advanced calculating machine to calculate and print mathematical tables in 1812 and in 1834 conceived a machine designed to evaluate any mathematical formula and to have even higher powers of analysis than his original Difference Engine of the 1820s. Only part of the machine was completed before Babbage's death in 1871.
