Assassin bug writes: From the journal Nature —
John Backus, who died on 17 March, was a pioneer in the early development of computer programming languages, and was subsequently a leading researcher in so-called functional programming. He spent his entire career with IBM.
Fortran remained Backus's lasting contribution to computing, for which he was awarded the National Medal of Science in 1975 and the Turing Award of the Association of Computing Machinery in 1977 — computer science's highest honour.
