therefore had an open mind to possibilities that others might not have Throughout the 1980s, Thompson and Ritchie continued revising Research Unix, which adopted a BSD codebase for the 8th, 9th, and 10th editions. He worked at Entrisphere, Inc. as a fellow until 2006 and now works at Google as a Distinguished Engineer. Universities began to train their students in Unix and C, and when they graduated they took the culture into industry, where it blossomed. In the 1980s, following deregulation, AT&T began to assert its intellectual property rights in Unix. Multics was in crisis when he arrived at the research organisation. According to a 2009 interview, Thompson now uses a Linux-based operating system. testing on it. Ritchie and Thompson then set out to improve the used to write programs and run them, companies began using Bell Laboratories © 2020 Guardian News & Media Limited or its affiliated companies. Almost all programs that work with regular expressions today use some variant of Thompson's notation. thinking back on experiences when I've returned and then often wish NA. Thompson was instrumental in the design and implementation of the Plan 9 from Bell Labs, a new operating system utilizing principles of Unix, but applying them more broadly to all major system facilities. Some programs that were part of later versions of Research Unix, such as mk and rc, were also incorporated into Plan 9. them months to come up with a solution, but when they were finished they "Interview-Dennis Ritchie," the United States National Academy of Engineering in 1988. Dennis Ritchie, as far as I know, never married. This led them to a rethink. Personal life. Ritchie grew up in New April 12, 2019 and more popular in the early 1970s. [8] After initial work on Unix, Thompson decided that Unix needed a system programming language and created B, a precursor to Ritchie's C.[9], In the 1960s, Thompson also began work on regular expressions. Dennis was born to Alistair and and his wife, Jean, in the New York suburb of Bronxville and grew up in New Jersey, where Bell Labs had its Murray Hill site. "[2], Thompson received a Bachelor of Science in 1965 and a Master's degree in 1966, both in Electrical Engineering and Computer Science, from the University of California, Berkeley, where his master's thesis advisor was Elwyn Berlekamp. There were large blocks of "C" help build the system, one that was able to handle up to a thousand users The three of us got together and decided that we hated C++. and especially Unix. All rights reserved. Richard Stallman's development of GNU as a free form of Unix had not been mentioned. Bell Labs was responsible for the operating software. He was a student at Summit High School. Because of this it was easy to use in extremely structured and modular. Finally, a new and improved version was developed and named C, which, Ritchie mused, "left open the question whether the name represented a progression through the alphabet or through the letters BCPL". There he studied science and He is survived by : his wife Lydia Cook Ritchie; his children, Tamisha C. Ritchie of Kannapolis and Brian Keith Ritchie of China Grove; and his brother Gary Ritchie (Sylvia) of China Grove. Unix was written in machine language, which had a small vocabulary and did He was the co-author of the book "The C Programming Language". Piore Award in 1982, a Bell Laboratories Fellow in 1983, an Association In a 2009 interview, Thompson expressed a negative view of C++, stating, "It does a lot of things half well and it's just a garbage heap of ideas that are mutually exclusive. dial-in access, but smaller desktop computers were being developed, and [27], Ken Thompson is married and has a son. a problem but rather as a puzzle to be solved. Ritchie worked at MIT for many years helping develop, 1999 he was the recipient of the United States National Medal of [3], Thompson was hired by Bell Labs in 1966. for Computing Machinery Turing Award in 1983, an ACM Software Systems Content approved and certified by a member of the Echovita supervisory team. It took Ritchie and Thompson – usually together – received many honours and awards, culminating with the National Medal of Science awarded by President Bill Clinton in 1998. After the project was finished, just about the time that he graduated, interested in how they were programmed. Ritchie told In 2011, Thompson, along with Dennis Ritchie, was awarded the Japan Prize for Information and Communications for the pioneering work in the development of the Unix operating system. industry, he has had a profound influence on the entire computer Kenneth Lane Thompson (born February 4, 1943) is an American pioneer of computer science. This allowed Ritchie and Thompson to distribute Unix free of charge to universities and research institutions, which loved its clean, economical design. at once and could be run 24 hours a day. Institute of Technology (MIT). He was the son of Alistair E. Ritchie (father) and Jean McGee Ritchie (mother). Ritchie never saw programming as When asked how he learned to program, Thompson stated, "I was always fascinated with logic and even in grade school I'd work on arithmetic problems in binary, stuff like that. Unix at Berkeley would later become maintained as its own system, known as the Berkeley Software Distribution (BSD). became Lucent Technologies Inc., and began to sell Unix to developers, In 1970, Brian Kernighan suggested the name "Unix", in a pun on the name "Multics". , "It's not the actual programming that's Multics had promise, but the operating system was too complex to build. Unix and C provided the infrastructure software and tools that created much of today's computing environment – from the internet to smartphones – and so have played a central part in shaping the modern world. , http://cm.bell-labs.com-cm-cs-who-dmr-bigbio1st.html (January 2, 2007). The net result was that we pretty much slept for a week. Because of the speed with which "C" could be He was supervised by Patrick C. Fischer during his PhD. That was for the PDP-11, which was serendipitous, because that was the computer that took over the academic community. https://www.legacy.com/obituaries/salisburypost/obituary.aspx?pid=192371803 Investor's Business Daily [19], In late 2000, Thompson retired from Bell Labs. anyone but an expert few. While writing Multics, Thompson created the Bon programming language. So Ritchie The nearest thing to personal computing was the computer utility, a large mainframe machine that was used simultaneously, and at great expense, by a couple of dozen users sitting at typewriter terminals. He was a student at Summit High School. users today. twenty-first century, "C" is still the dominant language of In 2001, the ICGA Journal devoted almost an entire issue to Ken Thompson's various contributions to computer chess.[14]. to move data around from disk to screen to printer and back to disk for The new version of Unix was completed in 1973, and since it was written in C, it, too, was portable. Feedback from Thompson's Unix development was also instrumental in the development of the C programming language. Referring to himself along with the other original authors of Go, he states:[12]. Would you like to offer Dennis Ritchie’s loved ones a condolence message? computers. Thu 13 Oct 2011 22.25 BST larger computers they thought they would never want to leave. Earlier this year, the pair won a Japan prize. Other notable contributions included his work on regular expressions and early computer text editors QED and ed, the definition of the UTF-8 encoding, and his work on computer chess that included the creation of endgame tablebases and the chess machine Belle.
