The hot dog is a direct descendant of the German 'frankfurter' (from Frankfurt) and 'wiener' (from Vienna). German immigrants brought these sausages to the United States in the 19th century. Charles Feltman, a German baker, is often credited with opening the first hot dog stand on Coney Island in 1870, selling sausages in rolls so customers could eat them while walking on the beach. The name 'hot dog' reportedly came from a sports cartoonist who saw 'dachshund sausages' being sold at a baseball game and couldn't spell 'dachshund,' so he wrote 'hot dog' instead. The dish became a symbol of American leisure and is now a staple of Fourth of July celebrations, with Americans consuming an estimated 150 million hot dogs on that day alone.
