The first implemented compiler was written by Grace Hopper, who also coined the term "compiler", [6] [7] referring to her A-0 system which functioned as a loader or linker, not the modern notion of a compiler. The first Autocode and compiler in the modern sense were developed by Alick Glennie in 1952 at the University of Manchester for the Mark ...
Dennis MacAlistair Ritchie (September 9, 1941 – c. October 12, 2011) was an American computer scientist. [3] He created the C programming language and the Unix operating system and B language with long-time colleague Ken Thompson. [3]
The cover of the book The C Programming Language, first edition, by Brian Kernighan and Dennis Ritchie. In 1978 Brian Kernighan and Dennis Ritchie published the first edition of The C Programming Language. [18] Known as K&R from the initials of its authors, the book served for many years as an informal specification of the language.
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 C Programming Language (sometimes termed K&R, after its authors' initials) is a computer programming book written by Brian Kernighan and Dennis Ritchie, the latter of whom originally designed and implemented the C programming language, as well as co-designed the Unix operating system with which development of the language was closely intertwined.
Some programs that were part of later versions of Research Unix, such as mk and rc, were also incorporated into Plan 9. Thompson tested early versions of the C++ programming language for Bjarne Stroustrup by writing programs in it, but later refused to work in C++ due to frequent incompatibilities between versions. In a 2009 interview, Thompson ...
In the meantime, she published her first paper on the subject, compilers, in 1952. In the early 1950s, the company was taken over by the Remington Rand corporation, and it was while she was working for them that her original compiler work was done. The program was known as the A compiler and its first version was A-0. [26]: 11
