The Seymour Community Historical Society of Seymour, Wisconsin, credits Charlie Nagreen, now known as "Hamburger Charlie", with the invention of the hamburger. Nagreen was 15 when he reportedly made sandwiches out of meatballs that he was selling at the 1885 Seymour Fair (now the Outagamie County Fair) to make it easier for customers to eat while walking. The Historical Society explains that Nagreen named the hamburger after the Hamburg steak, with which local German immigrants were familiar.
