And yes it is hard to attribute something to one "person" because most things are made from pre-existing components (without electricity, no tv) I dont think anyone would say they invented the telephone.
I think I might prefer the US ones though. Better dough to topping ratio. Sometimes it feels like I am just eating a whole lot of dough.. Though the NY style ones I have had Wére extreeemly greasy though, and incredibly salt (like your monthly intake lol, I am a salt lover, but they were just barely within the limits of being edible..). Not sure if that is a common thing or just from the NY pizza delivery. I have a feeling the greasy thing is (going by what I see on tv) but the saltiness might not be the common thing.
