The story goes like this: Theophilus Van Kannel hated chivalry. There was nothing he despised more than trying to walk in or out of a building, and locking horns with other men in a game of "oh you first, I insist." But most of all, Theophilus Van Kannel hated opening doors for women.
He set about inventing his way out of social phobia. And that's how, 1888, Theophilus Van Kannel was awarded US Patent #387571 A for a "Storm-door structure," which would soon become known as the revolving door.
