Incredible man, just like his coworkers as Bell. All of that Bell Labs team is fantastic. Obvious Ritchie and Thompson are top dogs in our minds, but McIlroy and Cherry, and the rest of the gang that I don't know the name of are part of such an incredible part of CS history.
Kernighan is an excellent writer and in every interview I've ever seen, he's the most humble man you could imagine. Him and Ritchie taught me C, and to that I am appreciative.
