About this person
Dennis MacAlistair Ritchie was born September 9, 1941. Working at Bell Labs with Ken Thompson, he co-created the B programming language, then refined it into C - a lean, powerful language that became the foundation of modern software. Together they built Unix, an operating system whose design principles would reshape computing for decades. Ritchie died around October 12, 2011, a week after Steve Jobs, with far less fanfare and infinitely more code running in his wake.
