Meanwhile, officials in Frankfurt, Germany, say that hot dogs were invented in their city in 1487. And according to a third tale, a butcher named Johann Georghehner, who lived in Coburg, Germany, invented the hot dog during the late 1600s, and traveled to Frankfurt to promote his new food.
The man most responsible for popularizing the hot dog in the United States was, however, neither German nor Austrian. His name was Nathan Handwerker, a Jewish immigrant from Poland. In 1915 Handwerker worked at a hot dog stand at Coney Island, where he made a whopping $11 a week slicing buns. The hardworking Handwerker lived entirely on hot dogs and slept on the kitchen floor for a year until heâd saved $300, enough to start a competing stand.
