Die Gefahr, dass der Computer so wird wie der Mensch, ist nicht so gro — Konrad Zuse

"Undecided about whether to pursue art or engineering, he pursued engineering, but with a continued interest in design—for his senior school project, he had designed a city of the future (à la Fritz Langs Metropolis) based on a hexagonal grid. Like Alan Turing, Zuse was educated in a system that focused on a childs emotional and philosophical life as well as his intellectual life, and at the end of school, like Turing, Zuse found himself to be something of an outsider—to the disappointment of his very conventional parents, he no longer believed in God or religion."

"After the war Zuse constructed the Z4 computer, which became the world’s first commercially used computer. Zuse is also credited with writing the first programming language for his computers: Plankalkül, meaning calculus for programs. As an engineer by trade, Zuse was mainly focused on building a working machine that could perform calculations. He was not at all concerned with the theory of computation, which at that time was explored by renowned mathematicians in the academic world like Schönfinkel, Church, Post, Kleene, and Turing. Because of this, Zuse was not an established name in the academic community as a theoretical computer scientist. It is known however, that Turing and Zuse were familiar with each other’s work (Zenil, 2012). Although Zuse has always been more characterized as an engineer than a theorist. This is perhaps one of the reasons why his main work on computation in physics has been relatively unnoticed in the academic community for so long."

"Only too often the inventor is the idealist who, like Mephisto, tries to improve the world, only to be crushed by harsh realities. If he wants to carry through his ideas, he is forced to do business with the wielders of power, whose sense of reality is sharper and more developed."

"The rattling of the relays of the Z4 was the only interesting thing to be experienced in Zurichs night life!"

"Der Glaube an eine bestimmte Idee gibt dem Forscher den Rückhalt für seine Arbeit. Ohne diesen Glauben wäre er verloren in einem Meer von Zweifeln und halbgültigen Beweisen."
