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.
Another story credits Coney Island vendor Charles Feltman with selling the first hot dogs in buns there in 1867; Coney Island remains famous as a hot dog destination and host of the yearly Nathan's Famous International Hot Dog Eating Contest, which celebrated its 100th year in 2016, fittingly on the 4th of July.
