And then there was BCPL. And FORTH.

I disagree with Mr. Ryan, but I would suggest the following (I'm open to
being corrected by those with more knowledge :-)

AT LEAST ONE STACK is necessary for the implementation of a language that
provides recursion, but having two (or more) stacks does not imply that it
can't be done, it just changes the nature of how you do things.
