Charles Babbage, often referred to as the "Father of Computing," is credited with inventing the first mechanical computer, as well as with originating the concept of a programmable digital computer. Conceived in 1821, his Difference Engine No. 1, based on the mathematical principle of finite differences, and designed to tabulate and calculate polynomial functions, was the first complete design for an automatic calculating engine. His Analytical Engine, conceived in 1834, was a much more ambitious general-purpose programmable computing engine.
