As Konrad Zuse in 1935, claimed the entire living room in Berlin to a – as he calls it – "to construct a mechanical brain", amazed his parents not bad. It takes three years for the engineering student has completed the "Z1". It is an electrically powered, mechanical calculator – which does not work reliably.

The change, as Zuse, the error-prone mechanical calculating transmission replaced by electro-mechanical Relays. It is the not-yet-Mature "Z2", and finally, in 1941, the Assembly of the legendary "Z3" follows in a workshop in the methfessel Strasse 7, Berlin-Kreuzberg – in a Cabinet of the wall-sized machine, the first functional, fully automatic, program-controlled and in a binary Floating-point calculation working calculator in the story comes in.

It is the invention of the computer, and perhaps the most important technical Innovation of the 20th century. Century and the three years before the competition from the USA presents a similar machine (the "Mark I"). Nevertheless, no one is interested in first of all, for the ground-breaking technology.

in fact, Zuse's invention is in the throes of the 2. World war – also because nobody even recognizes the potential of its computing machine. The "Z3" at that time. a memory capacity of 64 words and a clock frequency of five Hertz with a power that exceeds that of today, every cell phone to have the a hundred million times Add to that his prototype is destroyed in December 1943 by a bomb attack.

Zuse, flees in 1945 to Bavaria, builds with the "Z4" in the flour warehouse, a bakery, a development of his calculating machine. Only in 1949, as the rumor of a revolutionary "mechanical brain" accomplished mathematics Professor Eduard Stiefel in Zurich, and he's tracking the "Z4" in the Allgäu, begins the triumphal procession of the Computer. And thus the Foundation for the development of a worldwide network of computer networks that enables exchange of data of Autonomous systems. Today, this technical Innovation is better known under the term "Internet".The picture shows Horst Zuse, son of the inventor Konrad Zuse. He built the his father developed Computer in its original size. The 1,000-Kilo machine is currently in the German Museum of technology in Berlin.
