The New York term hero is first attested in 1937. The name is sometimes credited to the New York Herald Tribune food writer Clementine Paddleford in the 1930s, but there is no good evidence for this. It is also sometimes claimed that it is related to the gyro, but this is unlikely as the gyro was unknown in the United States until the 1960s, according to some sources.
"Hero" (plural usually heros) remains the prevailing New York City term for most sandwiches on an oblong roll with a generally Italian flavor, in addition to the original described above. Pizzeria menus often include eggplant parmigiana, chicken parmigiana, and meatball heros, each served with sauce.
