    First Creation
    He finished the plan for his first computer the V1 in 1936. He later changed the name to Z1 in order to avoid an association with the V1-V4 military rockets. In 1938 the prototype for Z1 was completed.
  • Z2

    Z2
    Helmut Schreyer began to work with Konrad on Z1, and 1939 the Z2 computer was completed. Z2 was constructed with arithmetic and control units made by relays, but has the same memory of Z1.
  • The Beginning of Z3

    Z2 was successfully demonstrated to the Deutschen Versuchsanstalt fur Luftfahrt where he then received funding for the development of Z3.

    He finished the machine S1 in 1942.
  • Beginning of Plankalkul

    During 1942-1945 Zuse brainstormed on ideas as to how the machines he was creating could be programmed powerfully as he developed Z4.
  • S2 Computer

    He then created the S2 in 1944. It is considered the first process computer in the world.
  • Plankalkul

    Developed the first real programming language (Plankalkul) in 1944-1945.
  • World War 2

    The war made the development of Z4 hard, and Zuse eventually had to flee Germany in 1945.
  • Z4 Continued

    After some years he began to reassemble Z4.
  • Zuse KG

    Zuse was contacted by Professor Eduard Stiefel from ETH-Zurich who was impressed by his technology. After the encounter, he decided to create his own company, Zuse KG.
  • Z4 Sold

    Z4 was sold to ETH-Zurich. The computer went on the market in 1950. Z4 proved to be reliable as it worked without supervision
