|1954||USA||FORTRAN (FORmula TRANslation), the first high-level programming language development, was begun by John Backus and his team at IBMThe development continued until 1957. It is still in use for scientific programming. Before being run, a FORTRAN program needs to be converted into a machine program by a compiler, itself a program.|
|1954||USA||The IBM 650 is introduced. A relatively inexpensive decimal machine with drum storage, it becomes the first mass-produced computer, with some 2000 installations.|
|December 1954||USA||The NORC was delivered by IBM to the US Navy.|
|1956||USA||First conference on artificial intelligence held at Dartmouth College in New Hampshire.|
|1956||USA||The Bendix G-15 computer was introduced by the Bendix Corporation|
|1956||NED||Edsger Dijkstra invented an efficient algorithm for shortest paths in graphs as a demonstration of the abilities of the ARMAC computer. The example used was the Dutch railway system. The problem was chosen because it could be explained quickly and the result checked. Although this is the main thing many people will remember Dijkstra for, he also made important contributions to many areas of computing – in particular he should be remembered for his work on problems relating to concurrency, such as the invention of the semaphore.|
|1957||USA||First dot matrix printer marketed by IBM.|
|1957||USA||FORTRAN development finished. See 1954.|
|1957||USA||I have travelled the length and breadth of this country and talked with the best people, and I can assure you that data processing is a fad that won’t last out the year.— Editor in charge of business books for Prentice Hall.|

|12 Sep 1958||USA||The integrated circuit invented by Jack Kilby at Texas Instruments.Robert Noyce, who later set up Intel, also worked separately on the invention. Intel later went on to perfect the microprocessor. The patent was applied for in 1959 and granted in 1964. This patent wasn’t accepted by Japan so Japanese businesses could avoid paying any fees, but in 1989 – after a 30-year legal battle – Japan granted the patent; so all Japanese companies paid fees up until the year 2001 – long after the patent became obsolete in the rest of the World.|
