World’s First Large-Scale Computer Took Nearly 3 Years to Make, Occupied Space the Size of a Large Room

During World War II, the US Army had to calculate complex ballistic tables and unpack wartime codes. They needed an all-electronic calculating machine to do the job at electronic speed. In 1942, physicist John Mauchly proposed a machine on these lines and they built the Electronic Numerical Integrator And Computer, or the ENIAC, over the next three years.
