CHARLES BABBAGE CALCULATING DEVICE (1791-1871):

The first glimmer of a "thinking machine" came in the 1830s when British mathematician Charles Babbage envisioned what he called the analytical engine. Charles Babbage is s considered as “Father Of Computing”.  Babbage was a highly regarded professor of mathematics at Cambridge University when he resigned his position to devote all of his energies to his revolutionary idea.

 
                                       

In Babbage's time, the complex mathematical tables used by ship's captains to navigate the seas, as well as many other intricate computations, had to be calculated by teams of mathematicians who were called computers.

No matter how painstaking these human computers were, their tables were often full of errors. Babbage wanted to create a machine that could automatically calculate a mathematical chart or table in much less time and with more accuracy.

 His mechanical computer, designed with cogs and gears and powered by steam, was capable of performing multiple tasks by simple reprogramming—or changing the instructions given to the computer.
