At 1998 I had seen Thompson at AT&T where I had a short contract assignment from WebSci company. Really, I hadn’t seen him before but some guy said me, ‘Look, who is there…’ At this time I thought that Gods live in heavens but they are living and working on the Earth…. Ritchie was found dead on October 12, 2011, at the age of 70 at his home in Berkeley Heights, New Jersey, where he lived alone. First news of his death came from his former colleague, Rob Pike. The cause and exact time of death have not been disclosed. He had been in frail health for several years following treatment for prostate cancer and heart disease. His death came a week after the death of Steve Jobs but did not receive as much media coverage. Computer historian Paul E. Ceruzzi said after his death: “Ritchie was under the radar. His name was not a household name at all, but… if you had a microscope and could look in a computer, you’d see his work everywhere inside.”
In an interview shortly after Ritchie’s death, long time colleague Brian Kernighan said Ritchie never expected C to be so significant. Kernighan reminded readers of how important a role C and UNIX had played in the development of later high-profile projects, like the iPhone.
Other testimonials to his influence followed.
The Fedora 16 Linux distribution, which was released about a month after he died, was dedicated to his memory. FreeBSD 9.0, released January 12, 2012 was also dedicated in his memory.
I read a fine brilliant article about how Unix was born,
“The strange Birth and Long Life of Unix” by WARREN TOOMEY, December 2011
The impression is that sometimes the best and important achievements of mankind aren’t created THEN THAT ALL FOR but it is a simple contrary to all around us.

Ken Thompson and Dennis Ritchie Explain UNIX.
Segment from an AT&T Bell Labs (BTL) promotional film (circa 1980s) featuring UNIX creators Ken Thompson and Dennis Ritchie briefly explaining the UNIX environment. In cameo roles you’ll see UNIX luminaries Greg Chesson (in the wine red shirt) and Doug McIlroy (to the foreground of Greg). Also featured is a classic ASR-33 Teletype, BLIT displays (developed by Rob Pike, then of the Labs as well), and much more.
