UNIX turns 40 - in 1969 group of AT&T employees at Bell Labs, including Ken Thompson, Dennis Ritchie, Douglas McIlroy, and Joe Ossanna developed UNIX. Today Unix offered in many flavors and developed over time by AT&T as well as various commercial vendors (such as IBM, HP, Sun, Apple etc) and non-profit organizations. CW article concluded that after four decades, the future of the operating system is clouded, but its legacy will endure in form of Linux and Microsoft NT operating system:

In August 1969, Ken Thompson, a programmer at AT&T subsidiary Bell Laboratories, saw the month-long departure of his wife and young son as an opportunity to put his ideas for a new operating system into practice. He wrote the first version of Unix in assembly language for a wimpy Digital Equipment Corp. (DEC) PDP-7 minicomputer, spending one week each on the operating system, a shell, an editor and an assembler.


On a related note go and read "A Quarter Century of UNIX" book. It is based on interviews with the key software engineers who invented and built this powerful operating system, this book provides unique insight into the most important operating system in the modern computing environment.
