What is the origin of the 'hot dog'?
The birthplace of this all-American food is generally given as Frankfurt- am-Main in Germany in the 15th century. It travelled to America via hungry German immigrants in the mid-19th century.
But the history becomes unclear as a few competing stories try to explain how the 'hot dog' emerged and why it ended up in a bun.
The most popular tale has it that Charles Feltman, a Coney Island food vendor first sold 'dachshund sausages' on split rolls around 1871.
Later on a cold spring day in 1900, an ice-cream seller who was losing money decided to switch to selling the sausages instead.
He had the 'dachshunds' put in hot-water tanks and sent them into the stands yelling 'Red hot! Get your dachshund sausages while they're hot!'
Sports cartoonist Tad Dorgan heard this pitch and sketched a talking sausage snuggled in a warm bun. Unable to spell the word dachshund, he scribbled 'hot dog'.
