    Important Events regarding the COMPUTER

    Summaries of important events that marked a progression in the advancement of the computer.
  • First Bombe Completed

    First Bombe Completed
    Based partly on the design of the Polish “Bomba,” a mechanical means of decrypting Nazi military communications during WWII, the British Bombe design was greatly influenced by the work of computer pioneer Alan Turing and others. Many bombes were built. Together they dramatically improved the intelligence gathering and processing capabilities of Allied forces.

  • Complex NUmber Calculator Presented

    Complex NUmber Calculator Presented
    In 1939, Bell Telephone Laboratories completed this calculator, designed by researcher George Stibitz. In 1940, Stibitz demonstrated the CNC at an American Mathematical Society conference held at Dartmouth College. Stibitz stunned the group by performing calculations remotely on the CNC (located in New York City) using a Teletype connected via special telephone lines. This is considered to be the first demonstration of remote access computing.
  • Z3 Computer Completed

    Z3 Computer Completed
    The Z3 was an early computer built by German engineer Konrad Zuse working in complete isolation from developments elsewhere. It is called the Z3 because it was the third computer he had constructed.

  • Project Whirlwind Begins

    Project Whirlwind Begins
    Project Whirlwind begins. During World War II, the U.S. Navy approached the Massachusetts Institute of Technology (MIT) about building a flight simulator to train bomber crews. The team first built a large analog computer, but found it inaccurate and inflexible. After designers saw a demonstration of the ENIAC computer, they decided on building a digital computer. By the time the Whirlwind was completed in 1951, the Navy had lost interest in the project.
