Bourne spent nine years at Bell Labs with the Seventh Edition Unix team. As well as the Bourne shell, he wrote the adbdebugger and The UNIX System, the second book on the UNIX system, intended for the general public.
It was developed by StephenBourne, of ATandT Bell Laboratories, and was released in 1977 in the Version 7 Unix release distributed to colleges and universities.
StephenBourne carried into this shell some aspects of the ALGOL 68C compiler that he had been working on at Cambridge University.
Due to copyright issues surrounding the Bourne Shell as it was used in BSD releases, Kenneth Almquist developed a clone of the Bourne Shell, known as the Almquist Shell and available under the BSD license, which is in use today on some BSD descendants and in low-memory situations.
