Programming in the Linux Environment I Ken Thompson in 1969 made it work on DEC PDP-7 I Also involved, through ideas & contributions, were Rudd Canaday, Doug McIlroy, Joe Ossanna & Dennis Ritchie I Ritchie ported UNIX to the more advanced PDP-11 in 1970 I He then developed C language & its compiler to work with UNIX I In 1973, Thompson & Ritchie rewrote entire UNIX system code in C I It broke the tradition of writing OS in assembly language I With rewrite in C, UNIX became portable to any hardware UNIX I The UNIX operating system was developed in the late 1960s at AT&T Bell Laboratories
