He was best known as the creator of the C programming language, a key developer of the Unix operating system, and co-author of the book The C Programming Language. He was the ‘R’ in K&R (Kernighan and Ritchie). Ritchie worked together with Ken Thompson, the scientist credited with writing the original Unix.
