FORTRAN formally published

IBMInternational Business Machines — a major computer and enterprise technology company since the early 20th century. and John Backus presented the first widely used high-level programming language at the Western Joint Computer Conference.

What it was for

FORTRAN logoFORTRAN was for scientific and engineering work on mainframes — writing formulas that a compiler turned into fast machine codeBinary instructions a CPU executes directly — what compilers and assemblers ultimately produce.. Typical uses: nuclear reactor simulation, weather models, structural analysis, and physics research. Much legacy HPC code is still FORTRAN today.

Why it's here

FORTRAN is the starting point for compiler-based scientific and business computing at scale.

Why it mattered

It proved programmers could write in formulas and statements instead of machine codeBinary instructions a CPU executes directly — what compilers and assemblers ultimately produce., and it stayed in production for decades.

What it solved

Programming the IBMInternational Business Machines — a major computer and enterprise technology company since the early 20th century. 704 and similar machines required tedious low-level coding; FORTRAN automated translation to efficient machine programs.
