Hamburgers got their name from Hamburg, Germany.
According to the Food Lovers Companion, The name “hamburger” comes from the seaport town of Hamburg, Germany, where it is thought that 19th-century sailors brought back the idea of raw shredded beef (known today as beef tartare) after trading with the Baltic provinces of Russia. Some anonymous German chef decided to cook the beef. The hamburger made its first United States appearance at the St. Louis Louisiana Purchase Exposition in 1904. The hamburger is one of America’s favorite foods. It consists of a cooked patty of ground beef sandwiched between two bread halves, usually in the form of a round bun.
