I knew the guy who invented Naugahyde, nobody knows his name. This guy invents a comma and he's an scholstic hero.

 

Horace Hart in 1895. Horace was the inventor of the Oxford comma.  

The Oxford comma is a comma used before the final conjunction in a list of three or more items, like this….. 

Without Oxford comma: “Her favourite foods were chocolate, marshmallows, cake and chicken.”
With Oxford comma: “Her favourite foods were chocolate, marshmallows, cake, and chicken.”
