The story

After several years of development, FORTRAN reached IBM 704 users in 1957. Its team designed both a language and a compiler capable of producing efficient executable code, reducing dependence on hand-written machine instructions. This milestone concerns a usable system and its distribution, not the sole beginning of high-level languages or compilation. Standardization and implementations for other machines required further collective work.

Connections and context

Stored-program machines made instructions writable; higher-level languages changed how people expressed computational tasks. Compilers connected mathematical models and scientific calculations to electronic hardware.
