History of Computers

  • John Napier of Merchiston (1550 – 4 April 1617)

    John Napier of Merchiston (1550 – 4 April 1617)
    John Napier - inventor of calculating device, Napier Bones, also for Logarithym, Decimal notation.
    He was born in 1550, died April 4, 1617
  • Blaise Pascal invented the Pascaline

    Blaise Pascal invented the Pascaline
    A mechanical calculator nvented by Blaise Pascal, a French Mathematician. The pascaline could only Add & Subtract.
  • Joseph Marie-Jacquard

    Joseph Marie-Jacquard
    Joseph Marie-Jacquard invented the weaving loom for creating intricate woven fabric patterns. Napoleon Bonaparte granted Jacquard the patent on the loom. Jacquard used "punch card" method to create his patterns. The name "Jacquard pattern" is still used today.
  • Charles Babbage invented the Difference Engine

    Charles Babbage invented the Differnce Engine; first to receive a government grant from the Royal Astrological Society. Machine was to perform math calculation. Later he created the Analytical Engine--a scaled down model.
  • Herman Hollerith invents the Tabulating Machine

    Herman Hollerith invents the Tabulating Machine
    Herman Hollerith saved the 1890 census by inventing the Tabulating Machine. His invention was the results from a contest sponsored by the government for a faster way to calculate the U.S. Census. The 1880 census had taken 8 yrs. to count by hand.
    Herman Holleriths company, The Tabulating Machine Co, later was sold for $1 million and became IBM in 1923.
  • ABC Computer - Atanasoff-Berry Computer

    ABC Computer  - Atanasoff-Berry Computer
    was the first electronic digital computing device. The ABC was built by Dr. Atanasoff and graduate student Clifford Berry in the basement of the physics building at Iowa State College during 1939–42. It was the first to use Binary numbers. It also was non-programable
  • The Colossus

    The Colossus
    The Colossus Mark 2, was developed to break the German Code encrytor, the Enigma. Ten versions of the Colossus were built by the end of WW II. The Colossus was operational just in time to be used for the Normandy invasion.

    ENIAC ( Electronic Numerical Integrator And Computer), was designed to calculate artillery firing tables for the United States Army's Ballistic Research Laboratory. ENIAC was conceived and designed by John Mauchly and J. Presper Eckert of the University of Pennsylvania.

    The Univac, or Universal Automatic Computer, was the next-gen version of the pioneering Eniac built by J. Presper Eckert and John Mauchly at the University of Pennsylvania in the 1940s. Remington Rand bought the Eckert-Mauchly Computer Corp. in 1950 and sold the first Univac to the U.S. Census Bureau in 1951.
    It correctly predicted the 1952 presidential race with less than a 2% margin of error. CBS was skeptical but was impressed with the accurate outcome.
  • Integrated Circuitry - MICROCHIP

    Integrated Circuitry -  MICROCHIP
    Invented and patented by both, Jack Kilby and Robert Noyce in Mountain View, CA, near Silicon Valley.

    Integrated circuits replaced the vacuum tubes, allowing computer devices to be much smaller and compact. These IC's were crucial during the space race, allowing small computers to be placed aboard the Apollo spacecrafts; much like a laptop (today)
  • The Xerox Alto Computer

    The Xerox Alto Computer
    Researchers at the Xerox Palo Alto Research Center designed the Alto — the first work station with a built-in mouse for input. The Alto stored several files simultaneously in windows, offered menus and icons, and could link to a local area network. Although Xerox never sold the Alto commercially, it gave a number of them to universities. Engineers later incorporated its features into work stations and personal computers.
  • MICROSOFT - Bill Gates

    MICROSOFT - Bill Gates
    In 1973, Bill Gates became a student at Harvard University, where he meet Steve Ballmer (now Microsoft's chief executive officer). While still a Harvard undergraduate, Bill Gates wrote a version of the programming language BASIC for the MITS Altair microcomputer.
    In 1975, before graduation Gates left Harvard to form Microsoft with his childhood friend Paul Allen. The pair planned to develop software for the newly emerging personal computer market.
  • Apple Computer - Invented by Steve Jobs & Steve Wozniak

    Apple Computer -  Invented by Steve Jobs & Steve Wozniak
    Steve Wozniak designed the Apple I, a single-board computer. With specifications in hand and an order for 100 machines at $500 each from the Byte Shop, he and Steve Jobs got their start in business. In this photograph of the Apple I board, the upper two rows are a video terminal and the lower two rows are the computer. The 6502 microprocessor in the white package sits on the lower right. About 200 of the machines sold before the company announced the Apple II as a complete computer.
  • Atari

    Atari introduces the Model 400 and 800 Computer. Shortly after delivery of the Atari VCS game console, Atari designed two microcomputers with game capabilities: the Model 400 and Model 800. The two machines were built with the idea that the 400 would serve primarily as a game console while the 800 would be more of a home computer. Both sold well, though they had technical and marketing problems, and faced strong competition from the Apple II, Commodore PET, and TRS-80 computers.
  • McIntosh Computer

    McIntosh Computer
    Apple Computer launched the Macintosh, the first successful mouse-driven computer with a graphic user interface, with a single $1.5 million commercial during the 1984 Super Bowl. Based on the Motorola 68000 microprocessor, the Macintosh included many of the Lisa´s features at a much more affordable price: $2,500.
  • Apple - Introduces Ipad

    Apple - Introduces Ipad
    SAN FRANCISCO—January 27, 2010—Apple® today introduced iPad, a revolutionary device for browsing the web, reading and sending email, enjoying photos, watching videos, listening to music, playing games, reading e-books and much more. iPad’s responsive high-resolution Multi-Touch™ display lets users physically interact with applications and content. iPad is just 0.5 inches thick and weighs just 1.5 pounds— thinner and lighter than any laptop
