The Computer History Museum preserves descriptions of FORTRAN proposals, manuals, correspondence and the 1957 paper by Backus and colleagues. Together they document a language and compiler project at several stages. The dated 1957 release correspondence provides context beyond a later recollection of a single invention moment.
Why this entry uses a year
A conference paper, a manual and distribution of an implementation are different events within the development. This record uses 1957 as a year-level implementation milestone rather than inventing one day for the whole process. It does not claim that a proposal alone was a finished compiler or that no earlier translation systems existed.
Connect to the software layers
The software-revolution chapter distinguishes assembly, compilation, libraries, operating-system services and interfaces. Its bytecode example is invented and is not a recovered FORTRAN object program. The archive's catalogued material is a route to deeper study; this event's assessment does not claim to have executed the historical compiler.
