British mathematician Charles Babbage invented an analytical machine, based on similar principles to those that modern computers use.
This English philosopher and mechanical engineer originated the concept of digital programming. Some persons consider Babbage a "father" and credit him with the first that eventually led to more complex electronic designs but find all essential ideas in his engine. His varied work in other fields led to his described "preeminence" of his century.
The science museum in London displays incomplete parts of Babbage. From original plans of Babbage, people in 1991 constructed a functioning difference engine. Built to achievable tolerances in the 19th century, the success of the finished engine indicated that Babbage worked.
