FTN was spawned during the 1960s. Bitsavers has the GIM from 1966:

RUN was sort of a cheap-and-quick compiler. CDC kept around both, as
FTN compilation time was considerably longer (for obvious reasons).
RUN started out to be the do-everything compiler. You could stack decks
of FORTRAN and COMPASS in the same job and RUN would invoke the
assembler as needed and invoke the loader load-and-go at the end. The
JCL for that was simply "RUN."
