The word frankfurter comes from Frankfurt, Germany, where pork sausages served in a bun similar to hot dogs originated. These sausages, Frankfurter Würstchen, were known since the 13th century and given to the people on the event of imperial coronations, starting with the coronation of Maximilian II, Holy Roman Emperor as King. Wiener refers to Vienna, Austria, whose German name is “Wien”, home to a sausage made of a mixture of pork and beef (cf. Hamburger, whose name also derives from a German-speaking city). Johann Georg Lahner, a 18th/19th century butcher from the Bavarian city of Coburg is said to have brought the Frankfurter Würstchen to Vienna, where he added beef to the mixture and simply called it Frankfurter. Nowadays, in German speaking countries, except Austria, hot dog sausages are called Wiener or Wiener Würstchen (Würstchen means “little sausage”), in differentiation to the original pork only mixture from Frankfurt. In Swiss German, it is called Wienerli, while in Austria the terms Frankfurter or Frankfurter Würstel are used.
