"Unix is simple. It just takes a genius to understand it's simplicity"

Dennis Ritchie Introduction
Dennis MacAlistair Ritchie (September 9, 1941 – c. October 12, 2011) was an American computer scientist. He created the C programming language and, with long-time colleague Ken Thompson, the Unix operating system and B programming language. Ritchie and Thompson were awarded the Turing Award from the ACM in 1983, the Hamming Medal from the IEEE in 1990 and the National Medal of Technology from President Bill Clinton in 1999. Ritchie was the head of Lucent Technologies System Software Research Department when he retired in 2007. He was the "R" in K&R C, and commonly known by his username dmr.
Born- September 9, 1941 in
Bronxville, New York, U.S.
Died- October 12, 2011 (aged 70)
Berkeley Heights, New Jersey, U.S.
Known for- ALTRAN,B,BCPL,C,Multics,Unix
Awards- IEEE Emanuel R. Piore Award (1982)
Turing Award (1983)
National Medal of Technology (1998)
IEEE Richard W. Hamming Medal (1990)
Computer Pioneer Award (1994)
Computer History Museum Fellow (1997)
Harold Pender Award (2003)
Japan Prize (2011)
Fields- Computer Science
Institutions Lucent Technologies Bell Labs
Notable works-
Unix, a multiuser operating system. Several workalikes (commonly referred to as Unix-like systems) have been developed based on Unix's design. Some of these follow POSIX standards, again based on Unix.
B programming language
C programming language on which many currently used languages and technologies are based.
Unix Programmer's Manual (1971)
The C Programming Language (sometimes referred to as K&R; 1978 with Brian Kernighan)
