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.

In 1843 celebrated polymath Charles Babbage began work on an ambitious new calculating machines called the Analytical Engine. Only trial pieces remain, but if completed it would likely have been the size of a large room, and would have used steam power to conduct its calculations by mvoing a complex set of cogs, leavers and punched cards. Babbage wanted it to be capable of addition, substraction, multiplication and division, its design containing much of the architecture that we would recognise in a modern-day computer.

Babbage wanted it to be capable of addition, subtraction, multiplication and division, its design containing much of the architecture that we would recognise in a modern-day computer. Instructions and data were entered into the engine using punched cards, with small 'operation cards' specifying the operations to be performed, and larger 'variable cards' defining where the value should be stored.
