The Unix operating system was originally developed at AT&T's Bell Laboratories
by Ken Thompson, an employee engaged in various programming research projects.
With access to an abandoned DEC PDP-7 computer that had no software, Thompson
decided in 1969 to write a set of programs that would aid him in software
research. Over a period of several years, and with the help of fellow researcher
Dennis Ritchie, this set of programs evolved into a full operating system.
The Computer Science Division at University of California at Berkeley later
released a package of software for Unix originally named the Berkeley Software
Distribution. Unix was then adapted by UCB's Computer Science Research Group
for academic research and publishing. CSRG with the support of DARPA also
enhanced various Unix operating system facilities that were released as
BSD.
Linux was originally conceived in 1991 by Linus Torvalds at the University
in Helsinki, Finland. Torvalds' early releases were inspired on Minix, a
Unix clone developed by Andy Tanenbaum in the late 80s. As more people got
involved in Torvald's project, Linux began to resemble more of a "real"
Unix System V or BSD operating system.
