                        3rd December 2014
          Dennis Ritchie is known for his aid in the creation of the UNIX operating system and the
        C programming language. He first joined Bell Labratories in 1967. Shortly after, he began
        working on the first iteration of the UNIX operating system with his co-worker Ken Thompson.
        Thetwoweremotivated by the need for a simple and extensible computing platform that could
        support general purpose research.
          UNIX was initially developed using the BCPL programming language. After becoming
        frustrated with BCPL, Ken Thompson began the development of the programming language,
        B. B was the predecessor to C, and was much simpler. B had been used in development of early
        UNIX kernels, but it lacked the finesse and power needed to support complex data structures.
        It was eventually was superceded by the language C, again developed by both Dennis Ritchie
        and Ken Thompson.
          The C programming language is one of the most widely used programming languages in
        the world. C has had a strong influence on many other programming languages. Java, C++,
        C# and Objective-C all borrow concepts and syntax from C. Ritchie’s ideas of simplicity and
        clarity have persisted in these languages.
          Ritche not only made contributions in software, but he also has had lasting contibutions
        that have affected modern technical writing. According to Ritchie’s colleage Brian Kernighan,
        Dennis Ritchie had a talent for writing; Ritchie could express complex concepts in very sim-
        ple terms. Two of Ritchie’s publications, The C Reference Manual and The C Programming
        Language, are famous for their concise prose and clear examples. The C Reference Manual
        documents all aspects of the C language in a only 30 pages. The book The C Programming
        Language has become one the standard examples of proper technical writing and has influenced
        hundreds of technical publications in the last few decades.
          Dennis Ritche passed away in October of 2011. His simple and succinct writing style has
        had a profound and lasting impact on many future technical publications, and his work at Bell
        Labratories has influenced the way programs are written today.
