1955

Dartmouth College’s John McCarthy coins the term "artificial intelligence."


Bell Labs introduces its first transistor computer. Transistors are faster, smaller and create less heat than traditional vacuum tubs, making these computers more reliable and efficient.

On 2 October 1955 at 23.45 the power finally shut off, the ENIAC retired. It’s estimated to have done more arithmetic than the entire human race has done prior to 1945. Parts of the machine are exibited at the Smithsonian (Washington USA) and a few other locations in the USA (computerhistory.org).

(7) IBM 702

The first commercial machine completely constructed from transistors is put on the market by IBM: series 702

The high price of the transistors causeS that the sales are a flop. Still the trend is set by this machine.⁽¹⁾ As you will have noticed there are several "first" fully transistorized computers, but this is the first commercial one.

Allen Newell, J.C. Shaw and Herbert Simon develop IPL-II, the first artificial intelligence language.⁽²⁾

During the development of the programming language FORTRAN, Harlan Herrick introduces the high level language equivalent of a "jump" instruction in the form of a "GO TO" statement. In 1968 in an article Edsger Dijkstra will state "GO TO Statement Considered Harmful" thus setting the stage for more advanced (read: structured) programming.

William Shockley's Semiconductor Laboratory is the first company established in Silicon Valley, San Francisco Bay⁽²⁾

In March Computer Usage Company is the first software company to open for business. CUC is founded by Elmer C Kubie and John W. Sheldon(7)

1956

IBM brings out the "Magnetic Disk Memory" : RAMAC350. Look close at the picture at the right hand side you will see the cabinet of the RAMAC "harddisk"

The era of magnetic disk storage dawned with IBM's shipment of a 305 RAMAC to Zellerbach Paper in San Francisco. The IBM 350 disk served as the storage component for the Random Access Method of Accounting and Control.  This "machine" is man's height, contains 50 steel platters coated with a magnetic layer. The platters are mounted on a vertical shaft that drives them around. The read and write heads do not move. The total capacity of the system is 5 million bytes ("characters").⁽⁴⁾⁽³⁾

The first Operating System is designed by Bob Patrick en Owen Mock. The system gets the cryptic name of: GM/NAA-I/O and is installed on the IBM 704.

Researchers at MIT first begin experimenting with direct keyboard data input.

The first transistorized computer is completed, three TX-O (Transistorized Experimental Computer) at the MIT laboratories.(19) Another first is the TRIDAC to use transistors.
Computers based on transistors mark the beginning of the 2-nd Generation of Computers

APT (automatic Programmed Tool) is developed by D.T. Ross. With this piece of software one can create shortcuts in software development. The tool writes the programmers text or "macro's"  out in assembly.

The case against IBM of monopolistic practices is settled by forcing IBM to lease and sell its machines. But IBM ships still 55% of all the data processing equipment.

The first Pegasus, produced by the UK company Ferranti Ltd., went into service in March 1956, at a time when all of the computers installed in the UK were designed and built in Britain. Pegasus was noted for its reliability and ease of use. It was the first computer to have a general register set architecture – a feature now seen in most modern computers. 40 Pegasus machines were built by Ferranti Ltd. between 1956 and 1962. Number 25, the only one still working, was installed in a special gallery in the Science Museum, London(12)

A. Newell, D. Shaw and F. Simon invent IPL (Information Processing language)

The acronym AI - artificial intelligence - is coined by John McCarty

1957

Siemens (Germany) starts to produce the 2002 computer in series. It is one of the fully transistorized computers in Europe.

Digital Equipment Corporation (DEC) is founded by Ken Olsen and Harlan Anderson. Starting out with laboratory and scientific modules. Their first computer the PDP 1 (Programmed Data Processor) will be released in 1960 and will get many successful descendants. DEC will be one of the most important computer producers of the world.

G.W.A. Dummer, exhibits during  the Royal Radar Exhibition in England a model of an Integrated circuit.

Jack Kilby and Robert Noyce invent the SILICON WAFER. With this they lay the foundation of the: Third Generation of Computers.

John Bardeen, John Schrieffer and Leon Cooper (USA) develop a theoretical model for Super Conductivity. We shall see later that super conductivity becomes more important when the critical limits of chip design comes near. Critical means how many transistors or other elements can be integrated on one single chip without creating interference. In Dr. John Bardeen wins a Nobel Prize for work in Superconductivity

FORTRAN-1 is formally published. This first of all kind of high level languages is developed by John Backus and his team for IBM. FORTRAN uses notation that have a strong resemblance with those used in algebraic notation. For that Fortran will become very popular with scientists and technicians.

Control Data Corporation is founded by William C. Morris and a group of engineers (amongst whom Seymour Cray) from Sperry Rand

The first issue of Datamation is released.

Nippon Telegraph and Telephone Corp (Japan). develops the Musasino-1, the first parametron computer. It uses 519 vacuum tubes and 5,400 parametrons—logic elements based on the principle of parametric excitation and invented by Eiji Goto in 1954.

A first attempt to immitatie human intelligence in a simulacron is attempted by Herbert. A. Simon, Allen Newell & J.C. Shaw. They devise a logic theory machine (first proof by machine) the General Problem Solver (GPS). The method for testing the theory involves developing a computer simulation and then comparing the results of the simulation with human behavior in a given task.
