Charles Babbage

Charles Babbage is an English polymath who lived from 26th of December 1791 to 18th of October 1871. A polymath is a person who is and expert in a number of different subjects, Leonardo da Vinci is a polymath for example.
Charles Babbage was a mathematician, philosopher, inventor and a mechanical engineer. The concept of programmable computers originated from him.

Mathematics in these times were done by hand and printed on mathematical tables. Most of the time these tables were full of mistakes, it was in 1812 when the concept of machinery doing the maths came to him.
In 1822 Babbage began with what he called a difference engine, designed to compute values for polynomial functions. It calculated a series of values automatically. It used a method of finite differences, to make it possible to avoid multiplication and division. There was a problem creating the prototype, Charles and a Joseph Clement fell out over costs in 1831. It wasn't finished until after his time. He created an improved model in 1849 but didn't receive the funding needed. The machine wasn't constructed until 1991.
