In History
  • John Napier

    John Napier
    In 1614, a Scottish mathematician named John Napier invented a set of rods, which have become known as "Napier's Bones," that could be used to perform complex calculations.
  • Blaise Pascal

    Blaise Pascal
    During the 17th century, Frenchman Blaise Pascal built a machine that could add numbers up to 8 digits (99,999,999).
  • Joseph-Marie Jaquard

    Joseph-Marie Jaquard
    In 1801, Joseph-Marie Jaquard developed a weaving loom that used punch cards to replicate designs--a revoluntionary step towards computer input.
  • Charles Babbage

    Charles Babbage
    The first machine that actually approximated the idea of a computer, that is, input-execution-output, was conceived in 1832 by Charles Babbage--called the "Difference Engine."
  • Herman Hollerith

    Herman Hollerith
    In 1890, a punch card calculator was created by Herman Hollerith to count the U.S. Census. Because of this, the U.S. Censes was completed in just 6 weeks!
  • William S. Burroughs

    William S. Burroughs
    By 1900, several machines had been built rich rivaled the Analytical Engine in complexity. One of theses was invented by William S. Burroughs, and the Burroughs company went on to become one of the leaders in the computer industry.
  • Lee De Forest

    Lee De Forest
    In 1906, Lee De Forest invented the electronic tube. This vacuum tube made possible the development of electronic computers.
  • Need for Faster Calculations

    Need for Faster Calculations
    In 1939, electronic machines where developed for the purpose of breaking German encryption codes. These machines were the forerunners of modern computers.
  • Howard H. Aiken

    Howard H. Aiken
    In 1943, a computer developed at Harvard University by Howard H. Aiken was the first programmed controlled calculator.
  • Invention of Colossus

    Invention of Colossus
    In 1943, a computer named Colossus was completed in Great Britain. This computer took over the task of code breaking.
  • invention of the ENIAC

    invention of the ENIAC
    Electronic Numerical Intergrator and Computer. Capable of 100,000 calculations per second.
  • Invention of the Transistor

    Invention of the Transistor
    Each transistor could do the work of several electronic tubes, and each was smaller than a postage stamp.
