You all knew somebody was going to put this one up...
He was the composer who foretold musical events before they happened: quarter-tones, polytonality, multiple time- and key-signatures at the same time, tone clusters... all before any Schoenbergs or Bartoks or those guys ever so much as thought of their innovations.
But then again, the guy was ignored basically until all the aforementioned "innovations" were made, thus the (unjustified) confusion over who really thought them all up FIRST.
