Word Origin and History for felix frankfurter
"hot dog," 1894, American English, from German Frankfurter "of Frankfurt," because a smoked-beef-and-pork sausage somewhat like a U.S. hot dog was originally made in Germany, where it was associated with the city of Frankfurt am Main (literally "ford of the Franks on the River Main"). Attested from 1877 as Frankfort sausage.
