In 1969, Thompson and colleague Dennis Ritchie created the UNIX operating system at Bell Telephone Laboratories. If you give me the right kind of Tinker Toys, I can imagine the building.

It had an 18-bit word length and only four kilobytes of memory3 which was only small fraction of capacity of single modern floppy disk. The publication was noticed by the right people at the UCB, Ken’s alma mater, which led to the 1st copy of the operating system and was being shipped to that university.Ken Thompson decided to retire from Bell Labs in 2000 and has moved later to California. For Ken, the benefit was, plus the nostalgia, an opportunity to work with new groups of people and consequent additional intellectual stimulation which resulted in the UCB to become one of the two leading developers of UNIX.In 1983, Ken Thompson was named fellow by Bell Labs. It was noticed by the right people at UCB, Thompson's alma mater, and this led to the first copy of the operating system being shipped to that university. 58-64. He created the C programming language and, with long-time colleague Ken Thompson, the Unix operating system and B programming language. (1966) in electrical engineering and computer science from UC Berkeley. (1965) and M.S. During the late 1960s and early 1970s, Bell Labs colleagues Ken Thompson and Dennis Ritchie developed UNIX, a multi-tasking, multi-user operating system alternative to the batch processing systems then dominating the computer industry. Thompson and Ritchie were jointly cited for development of generic operating systems theories and specifically for implementation of UNIX operating system which they invented at Bell Laboratories. Unix is an operating developed at Bell Labs primarily by Dennis Ritchie and Ken Thompson. Fgrep, specialised for the case of multiple (alternate) literal strings, was written in the same weekend. "Unix and Beyond: An Interview with Ken Thompson," 1999 "Unix and Beyond: An Interview with Ken Thompson", Computer 32 (5), May 1999, pp.

It selected and printed lines from its file arguments that matched a given regular expression.

But at the same time it is also, and due to the fact that UNIX facilitated huge paradigm shift from various highly centralized mainframe computers to less expensive, smaller, and decentralized computers which could run standardized operating systems rather than these dictated systems by their manufacturers.

As Neukirchen observed, Thompson contributed to the development of computer chess. One is Richard Jensen's "Unix at 50: How the OS that powered smartphones started from failure".

The next morning I found a note in my mail announcing a program named grep. This return resulted in UCB becoming one of the two leading developers of UNIX (i.e., along with Bell Labs).Thompson retired from Bell Labs on December 1, 2000 and moved to California.In 1973 Thompson made his first public presentation about UNIX. Ken Thompson was born in New Orleans, Louisiana, in 1943. 1969 was magic year when UNIX was born, humans first went along to the moon, ARPANET was released (the precursor on the Internet), as well as a number of other interesting events occurred. Unix's ubiquity was a surprise, says Thompson The Japan Prize, one of the highest honors awarded for outstanding contribution to science and technology, was awarded jointly this year to Ken Thompson and Dennis Ritchie for the creation of Unix. In 2014, developer Leah Neukirchen spotted an interesting "/etc/passwd" file in a publicly available source tree of historian BSD … (1965) and M.S. The IEEE Computer interview with Ken Thompson.
