Henry Ford is known as the founder of the modern automotive assembly line, turning out identical Model T’s from 1908 and paying his workers enough to afford the new transportation. While the factories in Detroit did roll shiny new vehicles out of the factory, they also packaged up all the parts needed to produce the final product at plants around the country. Shipping a “kit” saved costs and brought the product nearer to the customer. The plant in Walnut Hills received the car kits from Detroit by rail, did the final assembly, and sold the cars locally or shipped them on to regional distributors.
Production ended in 1938. Sears bought the idled plant and used it as its farm store. In the late 20th century, it was used as office space; now it is mostly occupied by Children’s Hospital.
