As with the wheel, the "inventor" is lost to history. Very likely the "inventor" was part necessity, part circumstance, part ingenuity. Pizza has undergone a very slow process of evolution over the centuries, but it is definitely the cultures of the Mediterranean that deserve credit for creating it. Historical records suggest that people in ancient Egypt, Greece and Rome all ate things that are very similar to the modern pizza.
Some writers have considered the pizza an invention of the man who is responsible for making it an international phenomenon (but the fact that this man worked in a pizzeria makes it difficult to call him the father of pizza!).
In 1905, Gennaro Lombardi opened the first American pizzeria, Lombardi's Pizzeria Napoletana in New York City. The popularity of pizza exploded throughout the country when World War II servicemen returning from Italy raved about the great Italian dish.
