The wiener was first introduced in the U.S. by Antoine Feuchtwanger, who was from Frankfurt, Germany. Some people called this small sausage "franks". Then, at the old Polo Grounds in New York City in 1901, a concessionaire began selling the "franks" by yelling - "Get your red hot(s) franks here!"
A sport cartoonist, T. A. Dorian labeled them "hot dogs" by drawing the frank, or hot dog, as a dachshund dog on a bread roll.
