Analytical Engine
A general-purpose mechanical computer that Charles Babbage first described in 1837 and never finished.
Charles Babbage first described the Analytical Engine in 1837 as the successor to his difference engine. He saw that a more general design than the difference engine was possible.
Programs and data were to enter on punched cards, like those that directed the Jacquard loom. Babbage never completed any of his machines, because of conflicts with his chief engineer and inadequate funding.
Why it matters
It was proposed as a digital, mechanical, general-purpose computer more than a century before Konrad Zuse built the Z3 in 1941.
