  • Z1 Mechanical Calculator

    Z1 Mechanical Calculator
    Konrad Zuse completed the Z1 Mechanical Calculator (Originally called V1) in 1938. It contained many components of modern computers but was ultimately destroyed during the war in 1943.

  • Z2 Electromechanical Computer

    Z2 Electromechanical Computer
    In 1939, Konrad Zuse improved upon the Z1. He created the Z2. The mechanical switches of the Z1 were upgraded to Electromechanical switches.

  • Z3 First programmable Calculator

    Z3 First programmable Calculator
    In 1941, Konrad Zuse and Helmut Schreyer completed the Z3. It was the first programmable calculator and if given enough time could do the same calculations a modern computer can.

  • Torpedo Data Computer (TDC)

    Torpedo Data Computer (TDC)
    The Torpedo Data Computer was created by the United States Navy in 1943. It was used to help increase the accuracy of torpedoes on submarines.

  • Eniac(Electronic Numerical Integrator And Computer)

    Eniac(Electronic Numerical Integrator And Computer)
    John Mauchly Proposed the Eniac in 1943 and the design was competed by 1945. The machine could run calculations at electronic speeds and did 18,000 calculations. An interesting fact is that the women in the picture were the programmers. They are Jean Jennings and Frances Bilas and both had a degree in Mathematics.
