Who is Dennis

Dennis Ritchie was best known as the creator of the C programming language, a key developer of the UNIX operating system, and co-author of The C Programming Language, commonly referred to as K&R (in reference to the authors Kernighan and Ritchie).

ALTRAN

• ALTRAN was a FORTRAN extension providing rational algebra, developed by W.S. Brown, at Bell Labs around 1968

BCPL

• B is a programming language developed at Bell Labs circa 1969. It is the work of Ken Thompson with Dennis Ritchie. B was derived from BCPL, and its name may be a contraction of BCPL

Multics

• Multics (Multiplexed Information and Computing Service) is an influential early time-sharing operating system, based around the concept of a single-level memory. Virtually all modern operating systems were heavily influenced by Multics—often through Unix, which had been created by some of the people who had worked on Multics

UNIX

• Unix is a family of multitasking, multiuser computer operating systems that derive from the original AT&T Unix, development starting in the 1970s at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others.
