Pioneer of mainframe computing; designed IBM 704; chief architect of IBM System/360. [4] [5] Formulated Amdahl's law; also worked on IBM 709 and IBM 7030 Stretch. [6] 1939 Atanasoff, John: Built the first electronic digital computer, the Atanasoff–Berry Computer, though it was neither programmable nor Turing-complete. 1822, 1837 Babbage, Charles
George Robert Stibitz (April 30, 1904 [1] – January 31, 1995) [2] was an American researcher at Bell Labs who is internationally recognized as one of the fathers of the modern digital computer. He was known for his work in the 1930s and 1940s on the realization of Boolean logic digital circuits using electromechanical relays as the switching ...
The history of computer science began long before the modern discipline of computer science, usually appearing in forms like mathematics or physics. Developments in previous centuries alluded to the discipline that we now know as computer science. [ 1 ]

The oldest known recordings of computer generated music were played by the Ferranti Mark 1 computer. The Mark 1 is a commercial version of the Manchester Mark 1 machine from the University of Manchester. The music program was written by Christopher Strachey. 1951: US EDVAC (electronic discrete variable computer). The first computer to use ...
However, since 2000, the idea has resurfaced in new forms (see application service provider, grid computing, and cloud computing). In 1966, McCarthy and his team at Stanford wrote a computer program used to play a series of chess games with counterparts in the Soviet Union ; McCarthy's team lost two games and drew two games (see Kotok-McCarthy ).
[16] Turing left an extensive legacy in mathematics and computing which today is recognised more widely, with statues and many things named after him, including an annual award for computing innovation. His portrait appears on the Bank of England £50 note, first released on 23 June 2021 to coincide with his birthday.
In 1953, more than a century after her death, Ada Lovelace's notes on Babbage's Analytical Engine were republished as an appendix to B. V. Bowden's Faster than Thought: A Symposium on Digital Computing Machines. [78] The engine has now been recognised as an early model for a computer and her notes as a description of a computer and software. [65]
