F'90 lacked allocatable derived type components, but was otherwise very well thought out, and its major contributions (modules, free form, internal procedures, generic interfaces, ELEMENTAL, array syntax, POINTER/TARGET...) have held up well. Kind of a mixed bag since then, frankly (FORALL, LEN type parameters, FINAL, ENUM, DO CONCURRENT...)
Fortran first appeared in 1957... It's probably older than most people here on HN.
"The first significantly widespread high-level language was Fortran."
