History claims that a man known as Uncle Fletcher Davis created the first hamburger in the late 1880’s at a small café on the downtown square. According to legend, Uncle Fletch took his sandwich to the 1904 World’s Fair in St. Louis where the sandwich was first introduced. The McDonald’s Hamburger University has given this historic evidence their stamp of approval and in 2006 a bill was introduced into the Texas Legislature to make Athens, Texas, “Original Home of the Hamburger.”
