History: Although the Germans and Austrians disagree on who first invented the hot dog, the mention of sausage can be traced back to Roman times, but the first thing that caught the attention of the American public was the German "sausage" sausage. This sausage was very popular at the Chicago Columbian Exposition in 1893, and many people say that the hot dog bun was invented there.
