And the third-oldest is COBOL (it's at least as widespread as FORTRAN; arguably, it's even more widespread than both FORTRAN and LISP together, considering that it's used by pretty much every financial org on the planet).
It seems that, alredy from such an early time, the kind of languages we would end up creating was already pretty much set in stone: FORTRAN, as the grandady of languages aimed at scientists and mathematicians, that modern-day R, Python, Julia etc draw their heritage from; LISP as the grandmother of languages aimed to computer scientists and AI researchers, still spawning an unending multitude of LISP variants, including Scheme, ML and Haskell; and COBOL, the amorphous blob sitting gibbering and spitting at the center of the universe of enterprise programmers, that begat the Javas, VBs and Adas of modern years.
(Note that I'm referring to language philosophy and intended uses- not syntax or semantics).
(I'm also leaving out large swaths of the programming community: the Perl uses and the C hackers etc. It's a limited simile, OK?).
