The Turing machine was invented in 1936 by Alan Turing, [7] [8] who called it an "a-machine" (automatic machine). [9] It was Turing's doctoral advisor, Alonzo Church, who later coined the term "Turing machine" in a review. [10] With this model, Turing was able to answer two questions in the negative:
He was highly influential in the development of theoretical computer science, providing a formalisation of the concepts of algorithm and computation with the Turing machine, which can be considered a model of a general-purpose computer. [6] [7] [8] Turing is widely considered to be the father of theoretical computer science. [9]
BASIC (Beginners' All-purpose Symbolic Instruction Code) [1] is a family of general-purpose, high-level programming languages designed for ease of use. The original version was created by John G. Kemeny and Thomas E. Kurtz at Dartmouth College in 1963.

The analytical engine was a proposed digital mechanical general-purpose computer designed by English mathematician and computer pioneer Charles Babbage. [2] [3] It was first described in 1837 as the successor to Babbage's Difference Engine, which was a design for a simpler mechanical calculator.
Other languages still in use today include LISP (1958), invented by John McCarthy and COBOL (1959), created by the Short Range Committee. Another milestone in the late 1950s was the publication, by a committee of American and European computer scientists, of "a new language for algorithms"; the ALGOL 60 Report (the " ALGO rithmic L anguage").
