History of C
The C language was developed in 1970's at Bell laboratories by Dennis Ritchie. Initially it was designed for programming in the operating system called UNIX. After the advent of C, the whole UNIX operating system was rewritten using it. Now almost written in C.
The C language is derived from the B language, which was written by Ken Thompson at AT&T Bell laboratories. The B language was adopted from a language called BCPL (Basic Combined Programming Language), which was developed by Martin Richards at Cambridge University.
In 1982 a committee was formed dy ANSI (American National Standards Institute) to standardize the C language. Finally in 1989, the standard for C language was introduced known as ANSI C. Generally most of the modern conform to this standard.
