The jack-o-lantern tradition comes from an old Irish folk tale about a man named Stingy Jack. It was said that he was unable to get into heaven and was turned away from the devil because of his tricky ways. So he set off to wander the world looking for a resting place. For light, Stingy Jack used a burning coal ember in a hollowed out turnip. When the Irish immigrated to the U.S. during the Great Potato Famine of 1845-1850, they found that turnips were not as readily available like they were in the homeland. So they started carving pumpkins as a replacement for their tradition.
