History of Turnstiles
Turnstiles were originally used, like other forms of stile, to allow human beings to pass while keeping sheep or other livestock penned in.
The use of turnstiles in most modern applications has been credited to Clarence Saunders, who used them in his first Piggly Wiggly store.
