CHARLES BABBAGE
Charles Babbage, FRS (26 December 1791 – 18 October 1871)^[2] was an Engish Mathematician,philosopher,inventor and mechanical engineer originated the concept of a programmable coputer. Parts of his uncompleted mechanisms are on display in the London Science Museum In 1991, a perfectly functioning difference engine was constructed from Babbage's original plans. Built to tolerances achievable in the 19th century, the success of the finished engine indicated that Babbage's machine would have worked. Nine years later, the Science Museum completed the printer had designed for the difference engine, an astonishingly complex device for the 19th century. Considered a "father of the computer", Babbage is credited with inventing the first mechanical computer that eventually led to more complex designs.
