Description:  The original definition of Computer was any person who performed computations or was required to compute data as a regular part of their job function.  Throughout history several man-made devices, such as the Abacus and Slide Rule, have been built to aid people in calculating data.  This historical timeline covers the origins of the first mechanical and electronic computers to the beginnings of commercially available computers sold to the public.  This historical computer timeline will be continued to 2010 in the near future.

1786 – First computer concept, called the Difference Engine, was conceived on paper by Johann Helfrich von Müller.
1833 – First attempt at building the Difference Engine, called the Difference Engine No. 1, by Charles Babbage. The first automatic computing machine was not successfully completed. Charles Babbage also conceived of a general purpose programmable computing machine called the Analytical Engine. The Analytical Engine features many essential principles found in the modern digital computer
1843 – First working Difference Engine was built by Georg Scheutz and Edvard Scheutz based on Babbage’s work.
1941 – First electromechanical computer was the Z3 built by Konrad Zuse.
1942 – First fully electronic digital computing device was the Atanasoff–Berry Computer (ABC), but it was not programmable.
1943 – First programmable, digital, electronic, computing device was the Colussus designed by Tommy Flowers and was used for codebreaking. The Colussus was a program-controlled computer.
1943 -1945 – The first high-level programming language to be designed for a computer was called Plankalkül, created by Konrad Zuse.
1946 – First general-purpose programmable electronic computer was the ENIAC. The ENIAC was a program-controlled computer.
1949 – First practical stored-program electronic computer was the EDSAC.
1950 – First personal computer built was called the Simon. The plans were contained in articles written by Edmund C. Berkeley.
1951 – First commercially available general-purpose computer was the Ferranti Mark 1, just one month prior to the UNIVAC I.
