From the Brooklyn Historical Society:
“Today gourmet food trucks can be found in every major U.S. city, but the initial concept of the food truck and “mobile kitchens” have been around since the 1860s. It came as a part of the westward migration which helped in defining the U.S. as a pioneering country. The first transportable meals came from the American West and chuck wagons. The invention of the chuck wagon is attributed to the Texas Ranger, Charles Goodnight. He realized that having a mobile kitchen would make it easier when feeding hungry cattlemen. On the East Coast this same concept became known as the lunch wagons, which later on become diners.
The humbler beginnings of these mobile eateries have been elevated to a nationwide sensation, even spurring a TV show. There was also a recent episode on the History Channel which delves into the origins of the food truck in America.
