away with his Hamburger Steak and seemed so content that Old Dave offered his new carryout meal as a staple menu item at the end of 1880 in Athens, Texas. Fletcher had a stall with his wife at the St. Louis World's Fair of 1904. Texan journalist Frank X. Tolbert mentions a salesman named Fletcher Davis who served hamburgers in a café at 115 Tyler Street in Athens during the late 1880s. The locals claim that Davis was selling beef sandwiches during that time, without having a clear name for his invention. During the 1980s, the Dairy Queen ice cream chain filmed a documentary about the birthplace of the hamburger featuring Davis' story.
