In Chicago that year, the Colombian Exposition brought hordes of visitors who consumed large quantities of sausages sold by vendors. People liked this food that was easy to eat, convenient and inexpensive. Hot dog historian Bruce Kraig, Ph.D., retired professor emeritus at Roosevelt University, says the Germans always ate the dachshund sausages with bread. Since the sausage culture is German, it is likely that Germans introduced the practice of eating the dachshund sausages, which we today know as the hot dog, nestled in a bun.
Also in 1893, sausages became the standard fare at baseball parks. This tradition is believed to have been started by a St. Louis bar owner, Chris Von de Ahe, a German immigrant who also owned the St. Louis Browns major league baseball team.
Many hot dog historians chafe at the suggestion that today's hot dog on a bun was introduced during the St. Louis "Louisiana Purchase Exposition" in 1904 by Bavarian concessionaire, Anton Feuchtwanger. As the story goes, he loaned white gloves to his patrons to hold his piping hot sausages. Because most of the gloves were not returned, the supply began running low. He reportedly asked his brother-in-law, a baker, for help. The baker improvised long soft rolls that fit the meat - thus inventing the hot dog bun.
Another story that riles serious hot dog historians is how term "hot dog" came about. Some say the word was coined in 1901 at the New York Polo Grounds on a cold April day. Vendors were hawking hot dogs from portable hot water tanks shouting "They're red hot! Get your dachshund sausages while they're red hot!" A New York Journal sports cartoonist, Tad Dorgan, observed the scene and hastily drew a cartoon of barking dachshund sausages nestled warmly in rolls. Not sure how to spell "dachshund" he simply wrote "hot dog!" The cartoon is said to have been a sensation, thus coining the term "hot dog." However, historians have been unable to find this cartoon, despite Dorgan's enormous body of work and his popularity.
