[19] Ritchie's Turing Award lecture was titled "Reflections on Software Research". As part of an AT&T restructuring in the mid-1990s, Ritchie was transferred to Lucent Technologies, where he retired in 2007 as head of System Software Research Department. [2] First news of his death came from his former colleague, Rob Pike. Here is Dennis Ritchie’s obituary. Pike received word Oct. 12 that Dr. Ritchie’s body had been discovered last weekend. In 1970, Brian Kernighan suggested the name "Unix", a pun on the name "Multics". Nowadays, the C language is widely used in application, operating system, and embedded system development, and its influence is seen in most modern programming languages. A cause of death was not immediately available. [23][24], In 2005, the Industrial Research Institute awarded Ritchie its Achievement Award in recognition of his contribution to science and technology, and to society generally, with his development of the Unix operating system. Thompson then found an old PDP-7 machine and developed his own application programs and operating system from scratch, aided by Ritchie and others. He was the son of Alistair E. Ritchie (father) and Jean McGee Ritchie (mother). The company confirmed his death to The Associated Press but would not disclose the cause of death or when Ritchie died. [45] The official naming citation was published by the Minor Planet Center on 7 February 2012 (M.P.C. [21], In 1997, both Ritchie and Thompson were made Fellows of the Computer History Museum, "for co-creation of the UNIX operating system, and for development of the C programming language. I think the Linux phenomenon is quite delightful, because it draws so strongly on the basis that Unix provided. [27] He had been in frail health for several years following treatment for prostate cancer and heart disease. He suggested that many of the improvements he introduced simply "looked like a good thing to do," and that anyone else in the same place at the same time might have done the same thing. [25], In 2011, Ritchie, along with Thompson, was awarded the Japan Prize for Information and Communications for his work in the development of the Unix operating system. [11], During the 1960s, Ritchie and Ken Thompson worked on the Multics operating system at Bell Labs. Please enable cookies on your web browser in order to continue. He created the C programming language and, with long-time colleague Ken Thompson, the Unix operating system and B programming language. He had been in frail health for several years following treatment for prostate cancer and heart disease. Unix has been influential establishing computing concepts and principles that have been widely adopted. A … [36][37][38][39], Reflecting upon his death, a commentator compared the relative importance of Steve Jobs and Ritchie, concluding that "[Ritchie's] work played a key role in spawning the technological revolution of the last forty years—including technology on which Apple went on to build its fortune. We rely on readers like you to uphold a free press. C fundamentally changed the way computer programs were written. [34][35] Other testimonials to his influence followed. Linux seems to be among the healthiest of the direct Unix derivatives, though there are also the various BSD systems as well as the more official offerings from the workstation and mainframe manufacturers. [30], Following Ritchie's death, computer historian Paul E. Ceruzzi stated:[31]. A … The company confirmed his death to The Associated Press but would not disclose the cause of death or when Ritchie died. First news of his death came from his former colleague, Rob Pike. Later, B was replaced by C, created by Ritchie, who continued to contribute to the development of Unix and C for many years. [13], During the 1970s, Ritchie collaborated with James Reeds and Robert Morris on a ciphertext-only attack on the M-209 US cipher machine that could solve messages of at least 2000–2500 letters.

The company confirmed his death to The Associated Press but would not disclose the cause of death or when Ritchie died. [9] [10] In 2020, the Computer History museum worked with Ritchie's family and Fischer's family and found a copy of the lost dissertation. It sounds like a wild claim, but it really is true. "[22], On April 21, 1999, Thompson and Ritchie jointly received the National Medal of Technology of 1998 from President Bill Clinton for co-inventing the UNIX operating system and the C programming language which, according to the citation for the medal, "led to enormous advances in computer hardware, software, and networking systems and stimulated growth of an entire industry, thereby enhancing American leadership in the Information Age". Mr. Ritchie and Ken Thompson used C to write UNIX. [32] [14] Ritchie relates that, after discussions with the NSA, the authors decided not to publish it, as they were told that the principle was applicable to machines still in use by foreign governments.[14]. In the same interview, he stated that he viewed both Unix and Linux as "the continuation of ideas that were started by Ken and me and many others, many years ago. [16] They were so influential on Research Unix that Doug McIlroy later wrote, "The names of Ritchie and Thompson may safely be assumed to be attached to almost everything not otherwise attributed."[17]. "[40] Another commentator said, "Ritchie, on the other hand, invented and co-invented two key software technologies which make up the DNA of effectively every single computer software product we use directly or even indirectly in the modern age. [20] In 1990, both Ritchie and Thompson received the IEEE Richard W. Hamming Medal from the Institute of Electrical and Electronics Engineers (IEEE), "for the origination of the UNIX operating system and the C programming language".
