The Z1 was a motor-driven mechanical computer designed by German inventor Konrad Zuse from 1936 to 1937, which he built in his parents' home from 1936 to 1938. [1] [2] It was a binary, electrically driven, mechanical calculator, with limited programmability, reading instructions from punched celluloid film.
Konrad Zuse was born in Berlin on 22 June 1910. [21] In 1912, his family moved to East Prussian Braunsberg (now Braniewo in Poland), where his father was a postal clerk.Zuse attended the Collegium Hosianum in Braunsberg, and in 1923, the family moved to Hoyerswerda, where he passed his Abitur in 1928, qualifying him to enter university.

The Z2 was an electromechanical (mechanical and relay-based) digital computer that was completed by Konrad Zuse in 1940. [1] [2] [3] It was an improvement on the Z1 Zuse built in his parents' home, which used the same mechanical memory. In the Z2, he replaced the arithmetic and control logic with 600 electrical relay circuits, weighing over 600 ...
The Z4 was arguably the world's first commercial digital computer, and is the oldest surviving programmable computer. [1]: 1028 It was designed, and manufactured by early computer scientist Konrad Zuse's company Zuse Apparatebau, for an order placed by Henschel & Son, in 1942; though only partially assembled in Berlin, then completed in Göttingen in the Third Reich in April 1945, [2] but not ...
Zuse, however, did not know of Shannon's work and developed the groundwork independently [11]: 149 for his first computer Z1, which he designed and built from 1935 to 1938. Zuse's coworker Helmut Schreyer built an electronic digital experimental model of a computer using 100 vacuum tubes [29] in 1942, but it was lost at the end of the war.
Konrad Zuse completed the 'Z2' (originally 'V2'), which combined the Z1's existing mechanical memory unit with a new arithmetic unit using relay logic. Like the Z1, the Z2 lacked loop capabilities. The project was interrupted for a year when Zuse was drafted in 1939, but continued after he was released.
