But where was the cheese? Enter "Cocky" Joe Lorenzo, a perhaps overly confident manager at Pat's, who dropped a little Provolone to complete the masterpiece. Later, in 1952, Cheez Whiz hit the market and, again, the world was changed.
Word spread of the beauty that St. Pat wrought, and eventually the now-legendary Geno's popped open and spawned a neighborhood rivalry… both operated 24/7 cheesesteakeries, but now Geno's claimed to have been the first to add cheese. Whoever it was, your soul can rest easy, as hungry eaters and insulin manufacturers owe you a debt of gratitude.
