Kenneth Lane Thompson was born February 4, 1943 in New Orleans, Louisiana. His father was in the US Navy and the family moved often.
Thompson received a Bachelor of Science in 1965 and a master's degree in 1966 in Electrical Engineering and Computer Science from the University of California, Berkeley.
After graduation, Thompson and Dennis Ritchie joined the Bell Laboratories Computing Sciences Research Center in Murray Hill NJ. At the time, staff members of this group had considerable latitude in choosing research topics in computing theory, languages, programming and systems. Since 1964, members of the group had been participating in the design and development of the Multics timesharing system, along with developers from MIT's Project MAC and General Electric.
In 1969, Bell Labs withdrew from the Multics project. The Computing Sciences Research group members searched for other projects, and in particular for a computing environment with an on-line community that avoided the "big system mentality." Unix would provide such an environment.
Thompson wrote the first version of the Unix operating system for a Digital Equipment Corporation PDP-7 in a month, using a cross-assembler that ran on GECOS. The PDP-7 he used had only 4K of 18-bit words.
