词源

From the names of computer science pioneers John Backus and Peter Naur. The notation was developed by Backus in 1959 (as Backus normal form) to describe computer languages, specifically ALGOL 58, and expanded and used by Naur in the ALGOL 60 report (the result of a January 1960 meeting). The name change to Backus-Naur form was at the suggestion of Donald Knuth.
