Who was the first man to invent the computer?

English mathematician Charles Babbage (1792–1871) designed a mechanical computing machine called the "analytical engine." It is considered the forerunner of the digital computer, a programmable electronic device that stores, retrieves, and processes data.
While attending Cambridge University in 1812, Babbage conceived of the idea of a machine that could calculate data more rapidly than existing computing methods, and without human error. The Industrial Revolution (a period of technological development; c. 1750–c. 1850) had been underway for more than half a century, and the world was becoming increasingly complex. Human errors in mathematical tables posed serious problems for many rapidly growing industries. After graduating from Cambridge, Babbage returned to the idea of developing a device to facilitate computation. Beginning work in 1834, he spent the rest of his life and much of his fortune trying to build such a machine. Babbage's device used punch cards to store data, and was intended to print answers. Although he was unable to complete his invention, the "analytical engine" was the forerunner of the modern digital computer
