Charles Babbage was a famous mathematician, analytical philosopher, mechanical engineer and computer scientist from UK. He was the one who first came up with the idea of a programmable computer. A number of his unfinished mechanisms are put up for public show in the London Science Museum.

In the year 1991, working on Babbage's designed plans; a "difference engine" was accomplished which worked properly. Due to high error rate while calculating mathematical tables by humans, Babbage sought to find a way where this could be done mechanically. There were three various factors that kind of influenced him: his hate for untidiness, his working experience on logarithm tables and, accessible research work done on calculating machines done by Wilhelm Schickard, Blaise Pascal and Gottfried Leibniz.

He first spoke about the ideology of a calculating device in a letter written to Sir Humphry Davy in 1882.
