Dennis Ritchie was an American computer scientist notable for developing C and for having influence on other programming languages, as well as operating systems such as Multics and Unix
In the late 1960s and early ’70s, working at Bell Labs, Mr. Ritchie made a pair of lasting contributions to computer science. He was the principal designer of the C programming language and co-developer of the Unix operating system, working closely with Ken Thompson, his longtime Bell Labs collaborator.
“Ritchie’s influence rivals Jobs’s; it’s just less visible,” James Grimmelman observed on Twitter. “His pointer has been cast to void *; his process has terminated with exit code 0.”
