Computers – the History of the Calculating Machine
The museum opened its first exhibition on computers more than 30 years ago. This exhibition examines the amazing history of the development of computing technology across an area of 1,000 square metres.
Exhibition closedThe second half of the building is currently being renovated, which is why this area has been closed since 29 June 2022. The modernisation of the building is scheduled to be completed in 2028, the 125th anniversary of the museum's founding.
How were Computers born?
Computers have become an indispensable part of our everyday lives. But how has their technology developed over time? Embark on a voyage of discovery – from the very beginnings of computing technology and the accurate calculating machines of the 18th century, to Konrad Zuse’s first program-controlled computer, which ushered in the age of the universal computer. This would open up a new world in which ever larger amounts of data could be systematically displayed, stored and processed. Our journey then guides visitors through the information technology of the 1960s, from the introduction of the first computer chip to the development of home computers and large high-performance computers.
1735The oldest original mechanical calculating machine in the exhibition dates from around this period.
1941The year when Konrad Zuse created the world's first programmable binary computer, the Z3.

Mathematical Instruments and Analogue Computers
The Deutsches Museum collection contains a wealth of historical mathematical instruments. Sectors and protractors, astrolabes and sundials, slide rules and planimeters illustrate various analogue calculation methods with lengths and angles. The often great age of these instruments is irrelevant: used correctly, they still display the correct calculation results, thanks to their very precisely engraved scales. Electromechanical and electronic analogue calculators demonstrate the development of mechanical analogue calculating devices up to the 1960s.
Nowadays, we associate the term “digital” with any information that is processed by a computer. However, the word actually has its origins in the Latin term digitus (meaning finger). We use our fingers to count – so the oldest digital computing device is our hand! This gave rise to the English term "digit".
This exhibition area is all about the history and mechanisation of computing: how does calculation with an abacus work? Who invented the first calculating machine? What major challenges had to be overcome and what inventions were necessary? When did calculating machines become a mass product? You will find answers to all these questions here.
The age of the universal computer began in 1941 with Konrad Zuse’s first fully functional and programmable Z3 calculating machine. Experience first-hand the impressive difference in size of early computers: from early electromechanical relay computers to the electronic valve computers of the early 1950s, and the first transistor computers right up to the first computers with integrated circuits, or microprocessors. The exhibition also vividly illustrates the development of historical storage and output methods along with elementary logic circuits.
Cryptological Devices and Machines
Since the Second World War, the history of computer science has been closely intertwined with the history of cryptology. The exhibition’s cryptology cabinet features a small selection of cipher machines from the Deutsches Museum collection; it previews the forthcoming permanent exhibition “Image Script Codes”, which is expected to open in late 2021.
