One baker is likely responsible for several of New York's earliest pizzerias

Filippo Milone established at least six pizzerias in New York, including one that would later be called Lombardi's, widely considered to be the city's (and the country's) first pizza establishment. Milone died in 1924, leaving no children to tell his story. Researcher Peter Regas unearthed a 1903 advertisement, pictured below, from an Italian-language New York newspaper.

Pizza became more popular in Italy after it took off in the US

Pizza was invented in Naples, though it wasn't particularly popular outside the region.

It's something anthropologist Agehananda Bharati calls "the pizza effect."

Delmonico's was the first American fine-dining restaurant

The steakhouse opened in 1837 in Manhattan, creating what is now considered the first fine-dining restaurant in the United States, introducing gloved waiters, white tablecloths, and an à la carte menu.

The frozen pizza was invented in 1950

Pizza is believed to have been invented in Naples

Naples formally became a part of Italy in 1861.

Legend has it that the Margherita pizza was named after an encounter with Queen Margherita

The Queen of Italy, Margherita of Savoy, visited Naples in 1889. As the story goes, chef Raffaele Esposito of Pizzeria Brandi made her a pizza with basil, mozzarella, and tomato, to represent the colors of the Italian flag, and eventually named the pie in her honor. Historians, however, note that the facts don't line up: The proof of her visit to the pizzeria is suspected to be a forgery created when the business was in dire straits in the 1930s.

The American diner evolved from a 'lunch wagon' into a restaurant

Providence, Rhode Island's Walter Scott began serving homemade dishes from a freight wagon to late-night workers, who were looking for meals long after proper restaurants had closed for the night.
