(Update: if you're interested in pneumatic tubes, I've written more here.)

My big project -- possibly undergirding my dissertation in a year: Postal services and pneumatic tube systems in the late 19th and early 20th century, especially in Paris. I'm reading these services in terms of their urban interfaces, their material qualities and the interest in the 1870s-1890s of physical networks across cities. Paris is interesting because of an explosion of postal and telegraph products and services, the response to the siege of the city (Balloon Post!), and the shift from electric to material form to someone's doorstep in terms of message delivery. The Hôtel des Postes fascinates because of its ingenious interfaces within the building and its processing capability; the pneumatic tubes are fascinating because they make manifest the force of air and use it to literally propel information across a building or a city.

During the same four-year period when the word "interface" was first used, in which the notion of networks proliferated, Julien Guadet (1834-1908) designed the Hôtel des Postes (1880- 1884) in Paris, the central office for the French postal network. An enormous civic architectural undertaking, the Hôtel des Postes sorted, moved, marked, placed in sacks, audited, loaded and transported letters, periodicals and packets at high speeds, before sending them out again to their destinations. For Guadet and bureaucratic chronicler of Paris Maxime Du Camp, La Poste represented a living system that they described in anthropomorphic terms. Guadet described the postal system as epileptically fast; du Camp compared it to a heart that "draws in its correspondence and forces it back out to distribute in every direction." Beyond these biological comparisons, however, Guadet designed the Hôtel des Postes to operate as an ordinateur--a computer processor--atop the postal network. The Hôtel des Postes represents a nascent, modern approach to designing buildings, one that translated organizational, functional requirements into form.


Fueling communication through pipes that ran under cities at speeds of up to 50 km per hour, the pneumatic post served as an urban subterranean communication network from the 1850s into the early 21st century, first in Europe, then the United States, and by the early 20th century, South America and Australia. Depending on the city, pneumatic tubes shuttled telegrams or letters and packages, both commercial and personal, as an antidote to increasing urban congestion and traffic on the streets above. Messages delivered by pneumatic dispatch surfaced in post offices and train stations, where messengers carried them by bicycle (or later, motorcycle or truck) from the post or telegraph branch to their final destinations.   For commercial buildings, pneumatic tubes offered ready communication systems between and within any enterprises that required the movement of receipts and paper. At once buried and tangled, emerging into the interiors of buildings and offering varied interfaces for its users, the pneumatic tube presents an enigmatic image of modernity--the merger of construction and communication.

Pneumatic networks preceded electrification, first powered by steam and only by electricity in the early 20th century. They enjoyed a long lifespan. Implemented first in London in 1853 as an information conduit between the London Stock Exchange and the Central Post Office, the technology quickly transferred to other cities. Berlin began its Rohrpost in 1865; Paris built its first pneumatic networks in 1866 and began public Poste Pneumatique in 1879; Philadelphia followed suit for first class post in 1893 and New York in 1897. Urban tube networks existed for a surprisingly long time, remaining in operation until 1953 in New York, 1984 in Paris and 2002 in Prague (where it was only taken out of service by a flood that destroyed much of the tube infrastructure).

I must admit, I'm surprised to find myself heading toward a 19th century dissertation topic, and at that, one that deals with France. But working on tubes and postal services lets me explore the things that I love about tangible networks and interfaces. They make me realize just how much we have to learn from these old and often forgotten modes of transmission.
