The 1945 Amarillo invention and the 1949 Springfield opening
Ed Waldmire Jr. was born in Springfield in 1916 and grew up in central Illinois. He was drafted into the Army Air Corps in 1942 during World War II and served as a non-commissioned officer at the Amarillo Army Air Field in Amarillo, Texas through the latter half of the war. In Amarillo, Waldmire encountered a roadside vendor selling deep-fried hot dogs in cornmeal batter — a regional Texas Panhandle food concept that had existed in various forms since the 1920s but had not been commercialized at scale.
Waldmire and a fellow serviceman named Don Strand decided to develop a refined version of the Texas Panhandle cornmeal-hot-dog concept that could be produced consistently at commercial scale. Strand's contribution was the technical breakthrough: a specialized cornmeal batter formula that adhered to the hot dog consistently without separating during frying, and a vertical-rack cooking apparatus that allowed multiple hot dogs to be deep-fried simultaneously while being held by sticks rather than tongs. Strand patented the cooking apparatus design after the war.
Waldmire returned to Springfield in 1945 and spent four years refining the recipe and testing the commercial concept at local venues. He sold the corn dogs at the Lake Springfield public beach during summer 1946, at the 1947 Illinois State Fair, and at several smaller Springfield concessions through 1948. The original product was called the "Crusty Cur" — a name Waldmire's then-fiancée Virginia Pearce disliked intensely. Virginia suggested the name "Cozy Dog" instead, and the renamed product opened at the first dedicated Cozy Dog Drive In on South 6th Street in June 1949.
