Computer
In 1837, Charles Babbage proposed the first general mechanical computer, the Analytical Engine. The Analytical Engine contained an Arithmetic Logic Unit, basic flow control, punched cards, and integrated memory. It is the first general-purpose computer concept that could be used for many things and not only one particular computation. However, this computer was never built while Charles Babbage was alive, because he didn't have enough money. In 1910, Henry Babbage, Charles Babbage's youngest son, was able to complete a portion of this machine and perform basic calculations.
