back to article C and Unix pioneer Dennis Ritchie reported dead

C programming language inventor Dennis Ritchie is reported to have died. Rob Pike, a Google engineer and former colleague of Ritchie, said on Google+ that the 70-year-old, who was a founding developer of Unix and known as dmr, died at home over the weekend after a long illness. At the time of writing, Ritchie's web page on …

    Don't forget that he also co-wrote "The C Programming Language" which I still consider the gold standard in how to write a clear and yet concise book about a programming language.

    Of course some of that is simply a reflection on the simplicity of C itself, but it was the first non-BASIC programming book I read and I have yet to read a more clearly written (and short) programming book that is not a "nutshell" style reference.

    It's also a great demonstration of why nerds need to be good communicators.

    For me personally this is a far more significant passing than Jobs, and I say that as an Apple user.

    It's a shame that so few people (including in the industry) understand how much we owe to the old guard of early software pioneers, many of whom are still kicking around.

      Well said

        Oh dear indeed.

        While I use C++ a bit more because some of it features I'd keenly miss for those programs that benefit from them, the language is just a bit too large to fit in an elegant book. I like that its warts and quirks turn out to have (often deep, tricky, or obscure but most always) technical reasons, but there's something to be said for a less complex and much more elegantly describable language, too. So I do convert things that need no more than C so that a C compiler is all they need. And yes, my "dot h" can all be fed to a C compiler, too.

        Tangentially, with the proliferation of integrated development environments and general reliance on graphical user interfaces, computer- and thus also programming language books have tended to include lots of screenshots, exploding the books and making them that much more vulnerable to version changes. IE this generates lots of "virtual dead weight" in computer related books. There are also quite a lot of titles now-a-days, but very few genuine gems.

        C is by no means perfect, but it did strike a chord somehow, as does the book describing it. Something to remember, over a glass, but also as something to strive for.

    2. ThomH

      I quite agree

      Goldberg & Robson's Smalltalk-80 book is the only other thing I can think of that even comes close, but K&R is the gold standard. Ritchie did tremendous work bringing elegance to the internal structure and organisation of computer systems and deserves every compliment already posted here and a million more.

      Very much agree. As significant as Steve Jobs was in IT, Dennis Ritchie's impact was much deeper and wide-reaching.

        But completely true. Given the mainstream coverage of Jobs you'd think he could walk on water...

        One man created tools, and the other man created trinkets. Neither was evil, both will be missed. Dennis Ritchie will be missed by far fewer people though, despite having a greater effect. Hardly anyone you see in the street will know his name, let alone his accomplishments. Nobody will make a movie of his life.

      Both are related

      You know, it was Steve Jobs who brought down UNIX (yes, OS X is still UNIX and even certified) and Objective C (still c) to hands of general public.

    It was almost by chance that I found myself sitting in front of a Unix system and a shelf of manuals. For the first few months, I didn't realise that I was teaching myself the career that I would follow for the rest of my working life.

    With no previous computing background, I took to Unix, its philosophy, methods, and even the language of its documentation. This was computing, not marketing.

    The masses will probably never even recognise the name. The true innovators pass unnoticed.

    "Unix paved the way for many, many operating systems, including Linux."

    To put it mildly. In fact most operating systems are just versions of Unix, or thinly disguised versions. Linux, Android, OSX. And most embedded systems, at least in my house, routers, NASes, and so on, run versions of Unix.

        ISTR it was the "posix subsystem" of wnt that got certified, which may or may not still be supported, but certainly wasn't easily accessible (required to be separately installed? don't recall, but it was and is simpler to slap on cygwin or use mingw or something) and didn't come with much of any graphics support. Bit of a dead ducky in that pond. But hey, it could be certified and that's marketeering winings* right there. Windows NT was also designed by a well-known unix hater**, and that's clearly noticeable.

        While we're talking defining influences, Unix itself was a third system after multics and its second system effect ailments, so in a sense it started out as a "3.0", to lasting success. Which is curious, seeing the long history of antagonism, lawsuits, and infighting. But let's not dwell on that today, eh. It did get a couple things very right and the result is useful to this day.

    Sic transit...

    It sadden me to learn the demise of one of the father of modern computing science, Dennis Ritchie, inventor of the C language and one of the founder of Unix system.

    He belonged to this generation of forerunners, he was what we can called a computer genius, and he was really able to write three lines of code without having two compilation errors.

    He was one of those people who built their reputation of visionary thanks to their technical skills, and not only on their abilities of crushing their competitors, terrorize their underlings and screw their dummy customers.

    A computer scientist who never cared about the visual appearance of C, or how many hours are needed for a chineese factory worker for building an UNIX machine.

    Someone who helped the humanity to go forward, and who invented things that we could not live without.

          swapping the operands when one is a non-lvalue so it is on the LHS (e.g. 0 in the example) causes a compilation error if "=" is present. It's a trick some people use to help prevent the mistake. It's not perfect because it doesn't work for comparisons of two l-values but it's popular in some places, nonetheless.

    Multics and Unix-in-your-pocket

    Unix was derived in part from Multics, a venerable OS from the 60s and 70s which was tied to GE (later Honeywell kit). Ritchie worked on the Multics project and realised that it did some things very well, and some things arguably very badly (and there were a lot of arguments in the 70s and 80s). Unix of course won the day, mostly because it was relatively lightweight and wasn't tied down to specific hardware.

    People who read El Reg probably understand what impact Unix and C has had. Even though Joe Public has probably never heard of Unix, all iPhones (via Mach) and Android smartphones (via Linux) run an OS derived from the work Lell Labs and Ritchie did. And C is pretty ubiquitous too.

    It took nearly 40 years for the technology developed at Bell Labs to end up in everyone's pocket. I wonder what he thought of that?

    Thanks Dennis. The world is a better place for the pioneering work you did.

    He changed my life far more than Steve Jobs

    K&R was, and remains, the only programming book I have just sat down and READ. It remains, decades later, as the shining example of what a programming book should look like.

    C was a good, solid, easy-to-learn language for it's time, but I can't say the world would be THAT different without it. But I CAN say that the way hundreds of thousands of programmers understand programming would never have been the same without him and the book he co-authored.

      Take any contemporary bit of IT kit, be it a Windows box, a Mac, iPad, iPhone, Android phone, Kindle, routers, sat-navs, etc, etc.....

      You will find that they are either based on Unix and/or created using C or one of its derivatives.

      Jobs had a big impact on a relatively small section of IT, Ritchie's work underpins almost all of it.

      And, please, C still *IS* a good solid language, without which a lot of us would be doing stuff like mucking around with assembler or forths. Well we still do don't we ;).

    A nice bloke too

    I was fortunate enough to have visited Bell Labs and met Dennis Ritchie (along with Ken Thompson, Brian Kernighan and Bjarne Stroustrup) in the mid eighties. What struck me, apart from the sheer intellectual horsepower he had, was what a nice bloke he was too.

    Having had the opportunity to share a beer and a pizza with him remains one of the more memorable moments of my professional life 25 years or so on.

    The work done by the Unix team (and he'd be the first to acknowledge the huge input of less well-celebrated people like Joe Ossana, Bill Plauger and many others) did change the world I knew, and in most respects for the better.

      You need both

      You need both, as with most good things. The Bell people and their predecessors were necessary to lay the foundations, build the tools to build the next generation. Jobs and his people were/are brilliant at using these to produce the technology in well designed, attractive packages of use to the "common man", to make it widespread and profitable outside computer specialists.

      C and UNIX, my bread and butter and delight for thirty years, was not doing well against Windows and others. Even Linux and Minix were just fringe activities in the wider world. Apple made it, is making it, mainstream. Android built on the market stimulated by Jobs, who built his on clever design and use of existing tools, most built on C and UNIX.

      You can not separate them. Both men in this case are extraordinary in their fields and all, including Windows phone and Android phone makers and users, should be grateful to both.

      Life is seldom "either or".

        I'm surprised by how few of the commenters seem to get that. The thing that sets Jobs apart from Gates et al was that he had an eye for good, clean and elegant design decisions (like the ones made by Ritchie and friends). Consider him an evil businessman if you will but at least his choice of technologies to use when building his evil empires wasn't based on tossing a coin (or even worse, breaking things deliberately).

    You never know, he might have taken stdout with him.

    Many thanks to DMR who has enabled me to make a nice living - sort of, I write Verilog.

    His work certainly changed my life.

    My development as a programmer went:

    1. BASIC. Mostly Applesoft at high school.

    2. Pascal. First language I learned at University. I was never much good at it.

    3. Fortran. Second language I learned at University. Much more to my taste.

    4. C. Third language I learned at University. I learned the basics in a weekend on a Pyramid 90x in the middle of 1986. Loved the language and have been using it ever since.

    I've learned and used other languages since then but C is my favourite.

    I'm currently a Unix/Linux system administrator but if ever asked I tell people that I'm really just a C programmer in disguise.

    Its worth pointing out that C had a huge influence on hardware evolution. The developers of the various RISC CPUs optimised almost exclusively for C and Unix performance.

    Sad news indeed.

    history of C

    Somebody in one of these posts pointed out that C came from B. I would add that B was a derivative of BCPL from Cambridge University, England, a good tool that I used briefly. Curiously, Bourne, of Bourne shell fame, was also English (an Algol specialist), if I remember correctly. One wonders what it was about England, specifically Cambridge, that gave rise to this.

    There is a straight line from reading the BOFH on Usenet in my mother's office twenty years ago, to installing Linux as soon as I could find it, to my first job at Lucent (with a brief stint on the Bell Labs side of the building maintaining the exptools distribution) to sitting at my desk typing this morning. The influence of dmr on this path is incalculable.

    A dear friend and mentor

    I am very saddened to hear about Dennis' passing. My thoughts go out to his family.

    His contribution to the computing and digital world has paved the advancement of modern technology and as a result he has touched possibly every human being on the planet in one way or another - even if they don't know it! He will be forever remembered alongside other brilliants such as Einstein, Edison, Bohr, et al.

    RIP Dennis.

    I'm sad for his loss as any human, but it's not like he did wonders for IT.

    C wasn't that good, almost indistinguishable from the assembler of the day. It still doesn't make sense nowadays if not for all the inertia. But I guess the ability to point out arcane features of the language makes many IT people feel intellectually superior.

    Pascal and a few others would have been a far better "default" language than C and VMS again a much better system than Unix (which was never even designed to be an operating system).

    But as jwz would say "Worse is Better" and wins any day. Can't argue with that.

    RIP dmr

    A very clever and influential chap, and a thoroughly nice guy too. Very sad to hear this news.

    RIP Dennis

    Started programming in basic 32 years ago in high school (punch cards being taken to the local uni to be run as a batch for us).

    Went out into the real work to work as a manual labourer for the next 10+ years. Then 20 years ago, decided that I was going to get out of manual labour and start learning how to program in real languages.

    Started off learning Pascal to learn proper structured programming then moved to C, ASM and CoBOL in that order. C stuck as my preferred language.

    Because of learning how to program in C, every other C based language is learnt in weeks, if not days because of the basic syntax and semantics.

    I started using unix based OS's about 20 years ago as well. Before that, it was the ever dodgy (Q)DOS as supplied by good old MS. To be honest, I think that Unix hands DOS a serious arse kicking.

    return (dmr != null ? 'Hello World' : 'Goodbye World');

    Sad day...

    I'm not going to get into the slanging match as to whose death is more important, I will leave that to the fanbois..

    All i know is this, as time passes the greats are moving on, one by one, and with each passing , it leaves the world that , a bit more dreay a place.

    I remember the 70 and 80 when all this stuff was new, and before the lawyers got involved , and the net was just a gleam in berner lee's eye. Spectrum/C64/Amstrad/BBC micro slanging matches , Elite.. those were truly the golden years :)

    A lot of good stuff to be remembered by.

    Didn't know the guy personally, didn't need to.

    K+R. A genuine classic in computer books, one many authors could learn from. My copy of the book went walkabout literally decades ago, and its replacement more recently, but the language is sufficiently compact and memorable that I don't actually need the book much.

    Thirty years or so ago, I read K+R, and "Software Tools (in Pascal)" co-written by the K in K+R. K+R changed the way my employers built programs, long after I had moved elsewhere. Sadly their first experience of C was via Whitesmiths, but they recovered eventually, especially once the VAX arrived.

    Respect is due. Sympathy to those close to him (including to bwk)

    Sad day - sad week.

    Read K&R some 30 years ago. Definitive whilst learning C on a PDP11-05.

    Forgotten it now, but...Time to buy it again.

    Respects to dmr

    I'm counting the number of devices now that run using C, Unix or derivatives , and it all started in 1971 with dmr's code. Numbers must have tripled each year! Matchless contribution indeed.

  65. BoxedSet

    I think the K&R bible on the C language is by far my most read and referenced book (even more so than the Hitchhikers Guide to the Galaxy!). A true legend and genius of the computer world. RIP

    He did so much more than Pope Jobs I and his collection of strokable, shiny bauble devices, zzz although we know who will be idolised more in the sycophantic media . . .
