Who is known as 'the father of the computer'?

Charles Babbage (26 December 1791 – 18 October 1871) was an English polymath. A mathematician, philosopher, inventor and mechanical engineer, Babbage is best remembered for originating the concept of a programmable computer.

Considered by some to be a "father of the computer", Babbage is credited with inventing the first mechanical computer that eventually led to more complex designs. His varied work in other fields has led him to be described as "pre-eminent" among the many polymaths of his century. John Tucker, Professor of Computer Science at Swansea University, however, argues that it was the Welsh mathematician Robert Recorde who first laid down the foundations of these concepts.

Parts of Babbage's 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.
