Charles Babbage built a simple part of the analytical engine before he died later that year. The analytical engine, the successor of Babbage's difference engine, was a mechanical general-purpose computer. Although partially built in 1871, Babbage pioneered the idea in 1837.

The Z3 was an electromechanical computer designed and built by German civil engineer Konrad Zuse between 1938 and 1941. The original Z3, previously named the V3, was destroyed two years after its completion (1943) by a bomb. A replica model of the Z3, built in the 1960's by Zuse's company Zuse KG, is on display at Deutsches Museum in Munich, Germany.

Alan Turing invents the Colossus computer, the machine that, for the remainder of the second world war, was operated at Bletchley Park and unscrambled codes. In June of the following year, Colossus Mark 2 began to operate and worked at five times the speed of Colossus Mark 1. Colossus computers decoded messages which had been encrypted by a device unknown to the British.

Between 1965 and 1967, E.A. Johnson of the Royal Radar Establishment in Malvern, England invented the touchscreen for air traffic control. During the early 1970's Frank Beck and Bent Stumpe, who were engineers for CERN, the European Organisation for Nuclear research, developed a transparent touchscreen which was based upon Stumpe's work at a television factory during the early 1960's.

On April 3rd 1973, researcher and executive of Motorola, Martin Cooper, made the very first phone call from a handheld mobile phone. The phone Dr Cooper used was a prototype weighing 1.1kg and measure 23 centimenters in length and 13 centimetres in depth. The phone allowed for half an hour of talk time and required ten hours to charge.

Steven Sasson invented the first digital camera at Eastman Kodak.The camera was just 0.1 megapixels, weighed eight pounds and photographed in black and white onto a cassette tape; the images would then be viewed on a television screen.

In 1988 the company, Fuji, revealed their Fujix DS-1P camera at the Photokina trade show in Köln, Germany,between October 5th and October 11th. This four hundred thousand pixel camera displayed a removable static RAM memory card which was developed by Toshiba and was the first of its kind.
