    History of programming languages

    For a detailed timeline of events, see Timeline of programming languages. For the ACM conference series, see History of Programming Languages.

    For broader coverage of this topic, see Programming language.

    The history of programming languages spans from documentation of early mechanical computers to modern tools for software development. Early programming languages were highly specialized, relying on mathematical notation and similarly obscure syntax.[1] Throughout the 20th century, research in compiler theory led to the creation of high-level programming languages, which use a more accessible syntax to communicate instructions.

    The first high-level programming language was Plankalkül, created by Konrad Zuse between 1942 and 1945.[2] The first high-level language to have an associated compiler was created by Corrado Böhm in 1951, for his PhD thesis.[3] The first commercially available language was FORTRAN (FORmul
