Zuse 4

The Zuse 4 or Z4 is at the same time the fourth calculator and the second computer designed by the German engineer Konrad Zuse

It is the second programmable computer multi-use.

It was carried out during the Second world war in 1944 then dismounted to protect it from the bombardments. It had then gone up after 1945 during several years.

Konrad Zuse then created the first private firm of manufacture of computer Zuse KG . This one delivered in September 1950 to the institute of mathematics applied of the federal Polytechnic school of Zurich (ETHZ) in Suisse Z4 (to which he had then added a perforated tape reader and an apparatus of perforation of these bands).

It was thus the first computer in the world with being sold, 5 months before English Ferranti Mark I and 10 months before American UNIVAC I.

It will remain in service with ETH Zurich until in 1954, year when it was transferred in France to the Franco-Allemand institute from Research from St Louis where he was in service until in 1959. One can admire it today in Munich with the Deutsche Museum .
