Dennis Ritchie was an American computer scientist who created the C programming language at Bell Labs in the early 1970s and, together with Ken Thompson, rewrote the Unix operating system in C, which made Unix practical to port across different kinds of computer hardware for the first time. Ritchie and Thompson shared the 1983 ACM Turing Award for their work on Unix.
