Brian Wilson Kernighan (/ˈkɜːrnɪhæn/; born January 1, 1942(民国31年)) is a Canadiancomputer scientist who worked at Bell Labs alongside Unixcreators Ken Thompson and Dennis Ritchie and contributed to the development of Unix. He is also coauthor of the AWK and AMPLprogramming languages. The "K" of K&R C and the "K" in AWK both stand for "Kernighan".
Kernighan coined the term Unix and helped popularize Thompson's Unix philosophy. Kernighan is also known as a coiner of the expression "What You See Is All You Get" (WYSIAYG), which is a sarcastic variant of the original "What You See Is What You Get" (WYSIWYG). Kernighan's term is used to indicate that WYSIWYG systems might throw away information in a document that could be useful in other contexts.
Kernighan's original 1978 implementation of Hello, World! was sold at The Algorithm Auction, the world's first auction of computer algorithms.
In 1996, Kernighan taught CS50 which is the Harvard University introductory course in Computer Science.[5] His students on CS50 include David J. Malan who now runs the course.
