Found an interesting article:
"The oldest known chili recipe is "Pappy's Chili Carne" and is dated 1845, the year of Texas' statehood. Pappy was a 3rd generation chuckwagon cook that sold his chili on the trails of San Antonio, feeding ranchers, cowboys, and workers. He would cook the chili in Dutch Ovens with hot coals and would ring his lunch bell when the chili was ready to serve, usually after about four hours of cooking. The recipe included the controversial ingredient beans, as well as beef, tomatoes, onions, various spices, and chili powder labeled "Mexican Chili", believed to be ancho chili powder. Pappy started selling his chili to local watering holes by the pot, and would accept four mugs of beer as payment. The name "Chili Carne" started to spread all over Texas, and a local newspaper printed his recipe, with his permission, however, they forget to list the beans. This article was reprinted throughout the state, and Pappy was elated when he learned of the error. The lines at his chuckwagon tripled after the local establishments that started serving chili "forgot" the beans! Many believe Pappy purposely left them out of the printed article."
