The digital computer was born, but for now it was only an imaginary machine. At the end of the Second World War —during which he helped to decipher the Enigma code of the Nazi coded messages— Turing created one of the first computers similar to modern ones , the Automatic Computing Engine, which in addition to being digital was programmable; in other words, it could be used for many things by simply changing the program. Although Turing established what a computer should look like in theory, he was not the first to put it into practice.
That honour goes to an engineer who was slow to gain recognition, in part because his work was financed by the Nazi regime in the midst of a global war. On 12 May , Konrad Zuse completed the Z3 in Berlin, which was the first fully functional programmable and automatic digital computer.
Just as the Silicon Valley pioneers would later do, Zuse successfully built the Z3 in his home workshop, managing to do so without electronic components, but using telephone relays. On the other side of the war, the Allied powers did attach importance to building electronic computers, using thousands of vacuum tubes.
The first computer that was Turing-complete, and that had those four basic features of our current computers was the ENIAC Electronic Numerical Integrator and Computer , secretly developed by the US army and first put to work at the University of Pennsylvania on 10 December in order to study the feasibility of the hydrogen bomb.
Presper Eckert, occupied m2, weighed 30 tons, consumed kilowatts of electricity and contained some 20, vacuum tubes. ENIAC was soon surpassed by other computers that stored their programs in electronic memories. The vacuum tubes were replaced first by transistors and eventually by microchips, with which the computer miniaturization race commenced. But that giant machine, built by the great winner of the Second World War, launched our digital age. Nowadays, it would be unanimously considered the first true computer in history if it were not for Konrad Zuse , who decided in to reconstruct his Z3, which had been destroyed by a bombing in The replica was exhibited at the Deutsches Museum in Munich, where it is found today.
Focused on making it work, Zuse was never aware that he had in his hands the first universal computing machine. It depends.
