Where is the true home of hamburger?

The kind of beef we see in hamburgers , minced(切碎)beef, was possibly invented by Mongolians over 800 years ago. But who first put the beef between pieces of bread and called it a hamburger? Three different cities in the United States all say that they were the first to invent America’s favorite food.

Some people say that Fletcher Davis, from Athens, invented hamburgers. “Old Dave,” as people called him, was selling minced beef sandwiches in his lunch bar as early as the 1880s. Some years later, they say that a group of Germans called①his sandwich a “hamburger ” because people from the German city of Hamburger ate this kind of beef.

Other people believe that the hamburger came from a different American city.②coincidentally, its name was also Hamburg. The Menches brothers were selling pork sandwiches at a fair in 1885, but when there was no more pork, they used minced beef and gave it a new name, the “hamburger”.

The third possible inventor of the hamburger was Charlie Nagreen, also known as “Hamburger Charlie,” from Seymour. He said that in 1885 he invented the world’s first hamburgers. Seymour now celebrates the invention of the hamburger every year. In 1989, it was the home of the world’s largest ever burger—over 2,500kg!
