John Warner Backus (December 3, 1924 – March 17, 2007) was an American computer scientist. He led the team that invented and implemented FORTRAN, the first widely used high-level programming language, and was the inventor of the Backus–Naur form (BNF), a widely used notation to define syntaxes of formal languages. He later did research into the function-level programming paradigm, presenting his findings in his influential 1977 Turing Award lecture "Can Programming Be Liberated from the von Neumann Style?"[1]

The IEEE awarded Backus the W. W. McDowell Award in 1967 for the development of FORTRAN.[2] He received the National Medal of Science in 1975[3] and the 1977 Turing Award "for profound, influential, and lasting contributions to the design of practical high-level programming systems, notably through his work on FORTRAN, and for publication of formal procedures for the specification of programming languages".[4]

John Backus retired in 1991. He died at his home in Ashland, Oregon on March 17, 2007.[5]
