Since its inception in 1914, San Giorgio has remained one of the most trusted names in pasta, and throughout its early years of expansion, a mid-century fire, and its eventual position within The Hershey Company, it has left a lasting impact on Lebanon County.

It all began with an Italian immigrant named Girolamo Guerrisi, who came to the United States from Calabria in 1907 when he was 17 years old. Guerrisi was alone when he arrived in Ellis Island, with the exception of several acquaintances from his hometown, Cittanova, and he found a place to stay with his cousin who lived in New York. For the next several years of his life, he remained in New York while he learned English and studied business methods. He moved to Lebanon in 1912 to set up the Keystone Fruit Company.
