H. Bockhacker of [[Berlin]] was granted German [[patent]] DE18349<ref>{{cite web|url=http://v3.espacenet.com/publicationDetails/originalDocument?CC=DE&NR=18349C&KC=C&FT=D&date=&DB=EPODOC&locale=en_V3 |title=esp@cenet — Original document |publisher=V3.espacenet.com |access-date=2009-07-08}}</ref> on December 22, 1881 for {{Lang|de|Tür ohne Luftzug}} or {{Gloss|Door without draft of air}}, which used a rotating cylinder with a door which after entering, the user then turned around to the exiting direction.

[[Theophilus Van Kannel]] of Philadelphia was granted US patent 387,571 on August 7, 1888, for a "Storm-Door Structure".<ref>{{cite magazine|last=Mars|first=Roman|title=Why Don't People Use Revolving Doors?|url=http://www.slate.com/blogs/the_eye/2013/11/07/revolving_doors_why_don_t_we_use_them_more.html|magazine=[[Slate Magazine]]|date=7 November 2013 |publisher=[[The Slate Group]]|access-date=7 November 2013}}</ref> The [[patent drawing]]s filed show a three-partition revolving door.  The patent describes it as having "three radiating and equidistant wings ... provided with weather-strips or equivalent means to insure [''[[sic]]''] a snug fit". The door "possesses numerous advantages over a hinged-door structure ... it is perfectly noiseless ... effectually prevents the entrance of wind, snow, rain or dust ..."  "Moreover, the door cannot be blown open by the wind ... there is no possibility of collision, and yet persons can pass both in and out at the same time." The patent further lists, "the excluding of noises of the street" as another advantage of the revolving door. It goes on to describe how a partition can be hinged so as to open to allow the passage of long objects through the revolving door. The patent itself does not use the term ''revolving door''.<ref>{{cite patent|title=Storm-door structure |country=US|number=387571 |gdate=August 7, 1888}}</ref>

An [[Urban legends and myths|urban legend]], dating back to perhaps 2008, claims that the invention was motivated by his [[phobia]] of opening doors for others, especially women; according to [[Snopes]], there is no evidence to support this.<ref>{{cite news|title=FACT CHECK: Was the Revolving Door Invented by a Man Who Disliked Holding Open Doors for Women?|url=https://www.snopes.com/revolving-door-inventor-women/|access-date=2 November 2017|work=Snopes.com|date=27 October 2017}}</ref>
