Lucaciewicz, as I recall. His notation was originally that one would add two numbers, a and b, as "+ a b." A modified form, adapted for stack machines, was to add two numbers with "a b +." Hence, _reverse_ Polish notation, but equally sound.
He also did some work on multi-valued logic, IIRC.
And for those of you are not LISP or Scheme fans, the language FORTH also uses Polish notation. RPN, in fact.
Yep, FORTH uses it for everything, including IF statements! e.g. < IF ."
