    Konrad Zuse, 1910–1995, Civil Engineer, Inventor and Entrepreneur


    “YOU COULD SAY I WAS TOO LAZY TO CALCULATE.”


    Paper, pencil and slide rule – the calculations that characterised the day-to-day life of a civil engineer in the 1930s were complex yet repetitive. Konrad Zuse thought that a machine would be much better at this monotonous and boring work. In 1941 he constructed the Z3, the first functional computer in the world.

    Safe in the cloud

    Cloud Computing makes IT simpler and cheaper. In the “cloud” everyone can rent as much computing power, storage capacity and software as they wish. However many private individuals and even companies are sceptical: they are anxious about the security of their data. Because of this, the Federal Ministry of Economics and Technology supports a variety of research programmes that aim to improve the reliability and security of Cloud Computing.

    Researchers at the Fraunhofer Society developed the concept to create a secure “Industrial Data Space”. In the future, companies from different industries will be able to network with each other in this open information domain without losing control of their data.

      Not without a card

      Credit card, debit card, insurance card, loyalty card – a life without chip cards barely seems possible nowadays. The first person to have the idea of storing information on cards was radio technician Jürgen Dethloff.

      In 1969 he registered a patent for a plastic card with an integrated circuit. In 1977 there followed a card containing a microprocessor – now used universally. The first microchip cards to hit the market were telephone cards. At the end of the 1990s bank cards followed, which were soon accepted in many shops across the globe. At the same time the tiny microprocessors could store and process increasing amounts of data: chip cards are increasingly turning into miniature computers.


      Almost everyone has at least one chip card in their wallet these days

        The birth of the computer

        The first computer in the world was set up in the living room of the Zuse family in Berlin. Their son Konrad had just completed his degree in Civil Engineering when he started to build a programmable calculation machine in 1935. The Z1 was the size of a double bed and prone to faults: the mechanical switch gear regularly jammed. Because of this, Zuse replaced the mechanical elements with relays, which are electromagnetic switches, in the follow-up model.

        But it was only the third version, the Z3, which really worked properly and was therefore the first programmable computer in the world. It was as early as 1949 that Konrad Zuse founded the first computer company in Germany, Zuse KG – but financial success eluded him.

          Dots and lines

          Back in the 1920s, electronics technician and inventor Rudolf Hell had the idea of splitting down text and images into dots and lines so that they could be transmitted electronically. In 1929 he built the first “Hellschreiber” (a teleprinter) at his company near Berlin. Fax machines work on the same principle to this day.

          In 1958 Hell began to develop a colour scanner to read and digitise images. Scanners were huge machines in those days. They only became portable when the first hand-held scanners were launched onto the market.

          During the course of his life, Hell registered a total of 127 patents. His objective was progress and practicality.

            Industry 4.0

            Steam engines, conveyors, information technology – the industrial world has already undergone three revolutionary changes. Now we are at the beginning of the fourth. The vision of Industry 4.0 is the intelligent factory: machinery, parts and transport equipment are networked with each other and with the internet via sensors, actuators and tiny computers. This enables them to exchange information constantly. Production and logistics are optimised; products can be customised to suit customer requirements. Furthermore, mechanical engineers, IT experts and logistics personnel work together across the disciplines.

              3-D without glasses

              3-D technology created an all-new film experience. Until now, viewers had to use a special pair of glasses, because the feeling of depth is only possible if the right and left eye are seeing different perspectives. Although new televisions already permit 3-D projection without glasses, the resolution is low because the screen has to display several views with varying perspectives at the same time.

              A team from Berlin is working on new image processing techniques to solve these problems. With these, a sensor detects the viewer’s position, whilst the software ensures that each viewer can see a perfect 3-D image – even if they are moving around the room.
