If there’s one food that transcends all social barriers in America, it has to be pizza. Pretty much everybody loves it. The USDA estimates that 37 million Americans partake of pizza daily.
But pizza was—obviously—not an original American food. Immigrants from Italy first introduced pizza to the United States in the early 1900s—but it was pretty much confined to Italian neighborhoods in New York, Boston, San Francisco and Chicago. In terms of retail, Gennaro Lombardi was the first to receive a license to make and sell pizza in 1905 in New York City.
Despite a bit of a resurgence in the 1930s, pizza didn’t really take off in the United States until after World War II. Around 150,000 GIs were stationed in Southern Italy during the war. They ate tons of pizza and loved it. This phenomenon was helped by one of the Army’s food suppliers—Hector Boiardi. He later became the famous Chef Boyardee. Then, returning GI Ira Nevin built the first gas-fired, ceramic-deck Bakers Pride pizza oven—which allowed for the explosion of pizza places nationwide. Pizza chains started cropping up in the late 1950s—starting with Pizza Hut and followed by Little Caesar’s and Domino’s. Now, pizza is, literally, ubiquitous.
But this “pizza revolution” in America would never have happened without hungry GIs demanding that amazing food they experienced in the south of Italy.
