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
Robert Anthony Kowalski (born 15 May 1941) is an American-British logician and computer scientist, whose research is concerned with developing both human-oriented models of computing and computational models of human thinking. [1] He has spent most of his career in the United Kingdom.
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 ...
[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.
Allen Newell (March 19, 1927 – July 19, 1992) was an American researcher in computer science and cognitive psychology at the RAND Corporation and at Carnegie Mellon University's School of Computer Science, Tepper School of Business, and Department of Psychology.
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 ...
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]
