In a career that not only spanned modern computing but defined it, he developed many tools and systems that we take for granted today. He received a Turing Prize in 1983 for his services to the industry, but even then he didn't slow down: he had a sterling career with Bell Labs and Lucent until finally retiring in 2007."

During his epic career he developed FORTRAN, invented the BNF syntax for describing programming languages, pioneered functional programming — oh, and even picked up a Turing Award here and there. This ends a career that can only be described as legendary. See you around, John, and thanks for all the elegant hacks. We'll miss you."
