About Brian Kernighan
- Brian Wilson Kernighan (; born January 1, 1942) is a Canadian computer scientist. He worked at Bell Labs and contributed to the development of Unix alongside Unix creators Ken Thompson and Dennis Ritchie. Kernighan's name became widely known through co-authorship of the first book on the C programming language with Dennis Ritchie.
- Kernighan affirmed that he had no part in the design of the C language ("it's entirely Dennis Ritchie's work").
- He authored many Unix programs, including ditroff. Kernighan is coauthor of the AWK and AMPL programming languages.
- The "K" of K&R C and the "K" in AWK both stand for "Kernighan".
- In collaboration with Shen Lin he devised well-known heuristics for two NP-complete optimization problems: graph partitioning and the travelling salesman problem.
- In a display of authorial equity, the former is usually called the Kernighan–Lin algorithm, while the latter is known as the Lin–Kernighan heuristic. Kernighan has been a Professor in the Computer Science Department of Princeton University since 2000.
- He is also the Undergraduate Department Representative.
