I don't see why. LISP is just a year younger and COBOL is 2 years younger. And Algol, spawned a year after FORTRAN, is no longer used as such (although there is now GCC support for Algol 68) but spawned many "Algol-like" languages, including most of the languages used today ... and even modern Fortran can be considered "Algol-like", having evolved to include its block structure.

FWIW, I started programming in 1965, in FORTRAN II.
