Who Invented the Revolving Door?

Theophilus van Kannel invented the revolving door. He was granted the patent for the invention on August 7, 1888.

The invention’s name was “Storm-Door Structure.”

This invention was originally a three-partition revolving door with weather-strips.

The main purpose of this invention was to prevent strong drafts of wind from entering a building when a door was opened.

So, the revolving door was designed to be energy-efficient. It worked and works to this day like an airlock. In other words, it prevents drafts of cold or hot air.

This invention helped to reduce the amount of energy use by the HVAC system. By avoiding air drafts, there wasn’t a drastic temperature change when people entered or exited a building.

The revolving door was also invented because hinged doors didn’t work that efficient handling people traffic. In some hinged doors, only a person can enter or exit at a time.

While revolving doors have can allow more people to enter and exit at the same time.

Again, there is no proof of this story to be true. But surely, it is an interesting part of the history of the revolving door.
