In use; 1935

On September 9, 1932, The London Times printed an article following up on a “correspondence in The Times proposing that British railway stations might, like those in Japan, provide facilities for messages from one person to another to be displayed.” An electrical engineer had written to the paper, agreeing, and noted a device that he had heard of; an “automatic machine…to be installed at stations and other suitable sites, and on the insertion of two pennies facilities were given for writing a message that remained in view for two hours after writing.”

The Notificator

Primary Features

The notificator consists of a six to seven foot tall, shallow case with a glass face wide enough to display three approximately three by five inch wide columns that extend from the mid section of the machine to the top. Fixed to that mid section is a protruding “small desk or shelf…a glass window in the desk and a roll of paper or thin cardboard beneath.” For two pennies, “the window can be slid aside and a message written, which will then be turned onward, the window be closed ready for the next user. Each time a fresh message is written the shutting of the window will move a ratchet—the only mechanism embodied in the invention—and so place the column of messages one space higher” (Times 09/32). An attendant or owner of the device would only need to replace the roll of paper when needed. The height of the screen allowed a message to ostensibly remain for two hours, but the ratcheting mechanism means that this figure would be affected by how steadily the device was in use. Usage in many sites could relate to a variety of factors such as weather and time of day; a malfunctioning or rarely used notificator would presumably retain the same messages and display them as a constant.

August 1935 issue of Modern Mechanix & Inventions Magazine: "To aid persons who wish to make or cancel appointments or inform friends of the whereabouts, a robot messenger carrier has been introduced in London, England. Known as the "notificator," the new machine is installed in streets, stores, railroad stations or other public places where individuals may leave messages for friends... The machine is similar in appearance to a candy-vending device."


As indicated above, an apparently functioning Japanese train station system of publicly posting personal communications inspired The London Times to call for the institution of a similar system, resulting in their reporting on this device.

The notificator was provisionally patented in June of 1932 by Govan Gee of Winchmore Hill, London, England. Govan Gee also holds U. S. patents for an “apparatus for delivering change” filed in 1934 and a “means for extinguishing cigarettes, matches, and the like” filed 1938.


Without the examination of any actual notificator scrolls, it is not possible to speak conclusively on the machine's tensions in practice or the messages' literal content. Did the length of the page or the posture inducing structure of the machine generate certain handwriting tics or abbreviations? Did the machine buck certain graffiti laws? A notificator's optimum placement has been described as high traffic public places; the posting of potentially immoral or politically subversive messages may have upset members of certain classes.

Automated Vending

[[[Hero]]] (or Heron), a C1 greek mathematician, describes and depicts "a coin-operated device to be used for vending sacrificial water in Eygptian temples" in his Pneumatika, though none may have been produced (Segrave 3). Vending machines were introduced in the United States as early as 1880 and became a popular means of providing comestibles or services automatically in the mid-1920s stocked with groceries, candy, coffee, and most popularly, cigarettes. Kerry Segrave indicates that from 1929 through the 1931, industries and the media believed strongly in an automated future; that "robots could sell just about everything" (21).


It is unclear if a link exists between Govan Gee's notificator and a company called Notificator Development Limited, but a connection may help explain the device's seeming lack of popularity or use by introducing possible legal woes. Court case listings by The London Times document multiple occurrences of Aircraft Patents Ltd. v. Notificator Development Ltd. from late October through December of 1937. On December 21, a Mr. Justice Simonds orders “in the usual form…for the compulsory winding-up of Notificator Development Ltd.” If a company undergoes compulsory winding up, courts have appointed a liquidator to properly deal with all debts and affairs before the company ceases to exist.


While intended for single receivers, messages transcribed onto the notificator are never private


The Modern Mechanix blog posts digitalized finds from back issues of Modern Mechanix and Inventions Magazine; on April 30, 2006, the notificator article appeared online. Postings on two separate message boards discussing the notificator article from the Modern Mechanix blog (, while being anecdotal sources, make interesting contributions which may eventually provide further information on this concept.

"Sarah Lipman," posting on the blog Pasta&Vinegar in June 2007, suggests that these types of communication methods were in heavy use among European and Jewish survivors of World War II: "I’ve seen it mentioned in many (10+ books) where when Jewish survivors tried to track down any remaining friends, relatives or neighbors, they would go to their old town or to a Displaced Persons’ Center, where names would be written up on notes all over the walls. They’d add their name, some identifying information, and contact information, and then read every single note trying to find names they recognized. They would also return frequently to check new "listings."<ref>{{cite web|[[6/27/2007}} These message centers also appeared in the period of confusion immediately following the 2001 tragedy in New York City. The public nature of these notices has the potential to activate oral communications among a dispersed community, increasing the chance that a posting would reach an individual member.

Self described "Tube bore and lover of London's history," "Simon Greenwood's" post at the MobHappy blog (, July 2007; "Not to say that this doesn't exist but...I have genuinely never heard of this, and it looks like the sort of thing that the Museum of London or the London Transport Museum would have in its stores. My guess is that there might have been one set up as a demo somewhere, perhaps in the West End, but that it wasn’t adopted by the Underground, the railways or whoever wanted to put street furniture out in London." Although the notificator does not seem to have been in wide use, the outdoor setting of the first image of this page, if it is not staged, implies at least some use at a public site.

The dispersal of the notificator image and description from the Modern Mechanix blog to other web sites and message boards put bloggers in a position to be some of the first to draw connections between this device and some of its modern counterparts such as online community message boards and blogs or new technologies that allow one's mobile device to leave or find digital public notes in physical places.
