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
Alonzo Church (June 14, 1903 – August 11, 1995) was an American computer scientist, mathematician, logician, and philosopher who made major contributions to mathematical logic and the foundations of theoretical computer science. [2]
Stephen Cole Kleene (/ ˈ k l eɪ n i / KLAY-nee; [a] January 5, 1909 – January 25, 1994) was an American mathematician.One of the students of Alonzo Church, Kleene, along with Rózsa Péter, Alan Turing, Emil Post, and others, is best known as a founder of the branch of mathematical logic known as recursion theory, which subsequently helped to provide the foundations of theoretical computer ...
Neil J. Gunther – computer performance analysis, capacity planning; Jürg Gutknecht – with Niklaus Wirth: Lilith computer; Modula-2, Oberon, Zonnon programming languages; Oberon operating system; Michael Guy – Phoenix, work on number theory, computer algebra, higher dimension polyhedra theory; with John Horton Conway
Konrad Zuse designed and built electromechanical logic gates for his computer Z1 (from 1935 to 1938). Up to and during the 1930s, electrical engineers were able to build electronic circuits to solve mathematical and logic problems, but most did so in an ad hoc manner, lacking any theoretical rigor.
John Alan Robinson (9 March 1930 – 5 August 2016) was a philosopher, mathematician, and computer scientist.He was a professor emeritus at Syracuse University.. Alan Robinson's major contribution is to the foundations of automated theorem proving.
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]
Whirlwind, the first real-time computer was built at MIT by the team of Jay Forrester for the US Air Defense System, became operational. This computer is the first to allow interactive computing, allowing users to interact with it using a keyboard and a cathode-ray tube.
