When New York Penn Station opened in 1910, the Pennsylvania Railroad boasted in advertisements that their vast new station was built of travertine marble from the same ancient Italian quarries as the Coliseum and Pantheon. Old Penn Station was rich in the architectural language of Greece and Rome. The façade comprised a colonnade of massive, Doric columns that stretched almost 450-feet end-to-end; it was inspired from temples on the Greek Acropolis. The main waiting room, at 314-feet-long, 109-feet-wide, and 150-feet-high, was modeled on Rome’s Baths of Diocletian. The project was as much an aesthetic gesture to the emerging City Beautiful Movement as it was a political statement: The Pennsylvania Railroad was here to stay, as permanent as the Penn Station it built.
The finished station, however, was an architectural contradiction. The Neoclassical exterior concealed what was, belowground, an extensive and, at-the-time, hyper-modern system of tunnels, electric trains, and communication systems that conveyed millions of people, baggage, and mail from street-level to each of 21 platforms. Aside from the solid stone columns of the main façade, most of the interior was of thin limestone, marble, and plaster sheets mounted on a metal structural frame. The seeming permanence of the stone walls was a cover for the steel frame and modern technology within on which this Neoclassical stage-set rested.

.

.

Just over fifty years later, on October 28, 1963, demolition began. The Pennsylvania Railroad, burdened with debt and aging infrastructure, was selling off its most profitable real estate assets – its land, buildings, and equipment – to stay afloat until it declared bankruptcy by 1970. Through the same two Hudson River tunnels that building materials for the original Penn Station were delivered, some of the same rubble now passed. Much of this rubble was carted off and dumped in the New Jersey Meadowlands adjacent the tracks where commuter trains still pass. The Pennsylvania Railroad used, quite literally, the station’s technology to cannibalize itself, and as the foundations for the new, and current, Penn Station.
Searching for remnants of old Penn Station, I found historic photos from the New York Public Library, Historic American Buildings Survey, and Library of Congress. I returned to the same locations in fall 2019 to re-photograph these images from the identical camera angles. The resulting and visible ghost of the lost Penn Station presents a strong-clear vision of what Penn Station used to be, and by extension, what it could return to, given financial commitment and political will.

The current subterranean warrens represent a clean break from what was here before. As long as Madison Square Garden chokes Penn Station for air and light from above, the current lightless and oppressive Penn Station is here to stay. The current station’s cheap ceilings of corrugated metal, garish electric signage, and exposed concrete floors ironically proved more durable than the Roman marble and limestone of old. The current station is not so fleeting and has, in fact, existed longer on this site than the station before it.
Surprising still is how, for many New Yorkers, it seems inconceivable that the permanent and imposing appearance of the original station could, one day, simply vanish without a trace. This old station is more dream than reality, and it seems almost impossible to imagine the current arrangement as having anything to do with what came before. So little of the original station – and the pride in civic life and New York City this station stood for – remains visible. Interestingly, more of the original architectural fabric survives belowground than meets the eye aboveground.

In the five years that demolition and rebuilding lasted (from 1963 to 1968), Penn Station remained in active service. While builders demolished the old station above, commuters continued to pass by on the platforms and corridors below. For this brief moment, the two buildings lived side-by-side, until the present building swallowed almost all visible traces of the past. In spite of this loss, the confusing floor plan of the current Penn Station has much to do with remaining traces of the original. Column for column and void for void, the current Penn Station is built within the fabric of the original. The old Penn Station, completed 1910, had 21 tracks on 11 platforms. The new Penn Station has 21 tracks on 11 platforms. In the demolition process, not one track or platform moved. In the five-year re-construction process, none of the tracks and platforms were moved, and most of the stairs between concourse and track-level survived. This similarity enables us to situate parts of the old structure in relation to the new.

The above cross-section of old Penn Station’s waiting room shows the extent of change. The orange line indicates the elevation at ground-level to which the architectural fabric of the old building was demolished. Above this line, nothing of Penn Station survives. Below this line, most of the original structure, tracks, infrastructure, stairwells, and the general contours of the original rooms survive, except now hidden.
After the Roman Empire collapsed, its architectural monuments to empire and power fell into disuse; many were repurposed for more humble and practical purposes. The Coliseum became a stone quarry, the Roman Senate House a humble church, and the Theatre of Marcellus a medieval fortress. New purposes were developed in the shells of old monuments. When a building is reused and altered but still bears visible traces of its earlier form, architectural historians call this creation a palimpsest. A palimpsest is neither of the present nor of the past; it is a mixture of both. For instance, the two square fountains of the 9/11 Memorial in Lower Manhattan mirror the locations of the now-vanished Twin Towers. For a relatively modern and young city in world terms, Penn Station is New York City’s largest palimpsest.

“Cutaway illustrating the principle of adaptive reuse” Drawing by architectural children’s book illustrator, David Macaulay, proposes to discard the “non- functional” spaces of the medieval cathedral by erecting a Styrofoam drop ceiling just above the floor. Everything above is “superfluous” to the cathedral’s function.

The oppressively low ceilings of the current station are the structural division between the public areas belowground and the now private (formerly public) areas aboveground. These ceilings also align to the border between the infrastructure of the original station that survives and the architectural fabric that was lost.
The Pennsylvania Railroad made the decision that made the most economic sense: to keep the infrastructure beneath and merely decapitate the “non-functional” aesthetics of the soaring ceilings and open spaces aboveground. This was valuable land that could be put to more profitable use. Into these empty “air rights,” the corporation could insert Penn Station’s new functions of Madison Square Garden and office towers that would, at last, generate additional income. While exploring the station, I discovered this palimpsest valued the practical and made absolute economic sense: Who needs to enter the city on the scale of a titanic-sized god when humans require spaces no higher than 8-feet-high to pass through?

The nuances of this palimpsest become clearer from inside. Passengers entering the old station proceeded down a long shopping arcade to the waiting room and platforms. What was once public space is now the private lobby of the commercial offices aboveground. On the right hand side, in the shadows of the private lobby, stands a statue of Samuel Rea, president of the Pennsylvania Railroad. A century ago, Rea stood at the entrance and welcomed passengers and the public; he now stands and watches the corporate clients and office workers. In old Penn Station, an inscription beneath announced his name and title. In the current location, Rea is out of place and has no relationship with his surroundings; the once prominent inscription is almost invisible on the new tablet behind him.

From the street-level arcade, passengers descended into the cavernous waiting room, sunken a few feet belowground. While the room itself is gone, the contours of this room survive in the general footprint of the slightly sunken parking lot that now occupies the site. What was once public space is now private and patrolled by Madison Square Garden security guards who forbade me from standing at this location with my camera.

The design problems with the current Penn Station are similar to those of old Penn Station: too few tracks, too many passengers, confusing circulation, and outdated infrastructure. After all, it is not the engineering and infrastructure that set these two buildings apart, as brick-for-brick and beam-for-beam, the 1960s rebuilding did not generally alter the areas belowground. This early- twentieth century infrastructure was, after all, designed to handle no more than 200,000 passengers-per-day, and yet now struggles under the burden of 650,000-per-day. Instead, it is the envelope around this infrastructure that was rebuilt in the 1960s, and whose loss the public and historians now mourn.

The columns in the foreground were added in the 1960s to support the weight of Madison Square Garden. The columns in the distance are original to 1910. The 1960s modernist buildings above conceal below what is, in essence, mostly early-twentieth century infrastructure.

Generations of New Yorkers hoped Penn Station would one day be restored with an architectural monument befitting New York City and the Western hemisphere’s busiest train station. In addition to rebuilding the General Post Office next door, other proposals over the years have called for rebuilding Penn Station exactly as it appeared before, or imagining a futuristic Penn Station emerging from the structural shell of the current Madison Square Garden, aptly entitled “Penn Station Palimpsest.” Precedent exists for both proposals. Some post World War II cities rebuilt their monuments and bombed out city centers exactly as they appeared before (such as Dresden and Warsaw), while others incorporated the rubble of the lost buildings into a modern building (such as Coventry Cathedral in England and Kaiser Wilhelm Memorial Church in Berlin). What we miss about old Penn Station was not the infrastructure, operations, or even the building itself, but rather the way this architecture made us feel dignified, and which we feel no longer.

Sticky problems with mapping historical New York City

Author’s time-lapse of Lower Manhattan’s street network development from 1609-2020

With help from digital and spatial mapping software, urban historians and geographers are examining city growth over time. Time-lapse evolutions are proliferating online of street network development in cities like New York City, Barcelona, London, and Berlin.
In most time-lapse studies, geographers encounter problems with lack of data. The older the city, the less data there exists about pre-modern population densities, demographics, and street networks. This lack of data is a problem when mapping the geographies of older cities.
A way around this problem is to look at street network development as a proxy for population size. The more streets there are built, the more people this city should have, the logic follows. In theory, this seems to work because cities with larger populations require more streets and occupy more built-up area. Knowing how much surface area a city occupies, coupled with knowing the average size and number of occupants in a typical block or building, allows a simple calculation of total population (people/acre x surface area). In addition, more historical data exists about street networks (from maps) than exists about population and demographics (from the census).
The problem with this method of using streets as a proxy for demographics is that cities that occupy more surface area and with more streets do not necessarily have more people. There are several reasons for this:
  • Available land: Some cities are built in harder geographies where acquisition of new land for development is prohibitively difficult to acquire, such as Venice. Manhattan’s high density and land values descend, of course, from a demand for housing that far exceeds supply on an island bordered by water.
    For instance, Oklahoma City covers 621 square miles with a 2018 population of only 650,000. New York City covers 302.6 square miles (half the area of Oklahoma City) and has a 2018 population of 8.4 million (thirteen times the population of Oklahoma City). Despite the major differences between these two cities – in population and surface area – the sum total of all streets if they were lined up end to end to form a continuous road is about the same for both cities. Similarly, the Manhattan grid is identical with the same street widths and block sizes from end to end of the island, even though population density in buildings within this grid varies from zero people per acre to over 200 per acre. Flexible street networks support any variety of housing types and densities, which means that street maps alone cannot reveal all the demographic nuances.
  • Zoning: Some municipalities are stricter than others in enforcing discrete and different land uses for residential, commercial, industrial, and mixed-use. The legal landscape of Manhattan has evolved significantly since the first zoning laws in 1916 restricted building height and density. Since then, city government has more clearly articulated rules about minimum apartment size, ventilation, fire escapes, and water supply. City government has also pulled industrial (and often more polluting) land uses away from residential areas in the name of health and safety.
    Although few of these legal and zoning changes are explicitly imprinted on the street network, they have a tangible and important impact on the quality of urban life. This zoning has largely resulted in lower population density because of restrictions on landlords cramming hundreds of people into the smallest space possible for the maximum profit. Now, over 40% of all buildings on Manhattan could not be built today for violating NYC’s zoning code for at least one reason. For instance, most buildings in neighborhoods like West Village and Lower East Side have not changed in a century; there is limited demolition and reconstruction every year. However, population density has significantly fallen as apartments grow larger and rooms formerly designed for multiple people in one room now only have one or two occupants. Even if the buildings and streets don’t change, the ways they are occupied can and do. In other words, changing in zoning and land use are not necessarily visibly imprinted on the plan of streets, particularly if those streets are rigid grids.
  • Transportation patterns: This is the biggest factor encouraging extensive and rapid street network development with low population density – i.e. sprawl. Before the nineteenth-century inventions of railways and streetcars, and the twentieth-century’s auto-based suburbanization, transportation and commuting were prohibitively difficult. People needed to live near to where they worked in what was largely a pedestrian and walking city on unpaved streets. Transportation challenges caused urban growth to be dense and built-up near to places of employment. As a result, many cities like Paris and London might appear small on old maps and occupy only a few square miles pre-1800, even though their population and economic importance were far larger than their surface area on maps leads one to assume. Again, less developed street networks and a smaller surface area of urban development does not neccessarily mean the corresponding city is less culturally or economically important.
Before the introduction of subways in the early twentieth-century, the difficulties of commuting greater distances over land and water drove a denser form of urbanism than today. Manhattan, by 1900, had over 2.3 million residents in comparison to only 1.6 million in 2020. These people were crowded into dense blocks with upward of half a million people per square mile. Over the following century, although Manhattan’s population declined by 700,000 people, the street network today is almost identical to a century ago – no smaller and no larger despite major shifts. These shifts in density and demographics simply do not show up on conventional street maps.
My animation below shows the evolution of Manhattan’s built-up area and population density from 1800 to 2010. Notice the steady upward march of street development versus the sudden spike in population density on the Lower East Side in 1910 at over 300,000 people per square mile (in contrast to less than 90,000 in 2010). For every decade after the construction of subways, there has been more urban sprawl, and the island’s population density has fallen. Notice how fluctuations in population density operate semi-independently of street-network development.

The animation on the left tells one story of continuous and north-moving development, while the animation on right tells a more nuanced story of population density. The challenge is to find a graphic representation that tells both stories, as neither visualizes all the nuances of urban history.

.

Possible Solutions

Discussing this problem of street networks with professor Kenneth Jackson, he suggested looking at building Floor Area Ratio (abbreviated FAR), which is the building height and size relative to the amount of land the building occupies. A skyscraper has high FAR. A trailer park has low FAR.
This method of representing urban growth would, in theory, produce three sets of maps: 1) a map of street network development; 2) a density map of people living per square mile; 3) a map of building height and size. This would complicate things but produce a far more accurate representation of urban growth (how to represent this and if enough data exists is another matter).
These three factors – streets, FAR, and population density – act semi-independently of each other. Different urban typologies will share a different mixture of these three factors. Only through analysis of the relationship between these three factors can one begin to understand the underlying demographic, economic, zoning, and historical differences between neighborhoods. For instance:
  • Downtown commercial district like Lower Manhattan: low population density but high FAR. In this case, FAR operates in inverse proportion to residential population density. Buildings can be dozens of stories but have no residents. There is a high density of tall buildings (i.e. high FAR) but low population density.
  • Slum like South Bronx in the 1980s: extensive (though poorly-maintained) street network development, high density, but low FAR because slum dwellings are typically informal without the construction quality required to build high. Buildings might be fewer than six stories and without elevators, as in the Lower East Side, but can contain hundreds or thousands of residents over the tenement’s lifespan. There is low density of tall buildings (i.e. low FAR) but high population density.
  • Suburb like Forest Hills, Queens: extensive (and well-maintained) street network development, low density, and low FAR. In wealthier suburbs, in particular, FAR is kept prohibitively low. Restrictions on minimum lot size required to build, minimum house size, and legal hurdles on subdividing larger lots into smaller ones all serve to enforce a certain quality and price of residential construction that often prices-out lower-income communities of color. There is low density development with numerous green spaces between free-standing homes (i.e. low FAR) and low population density.

.

The two density maps above are one illustration of FAR and help nuance Manhattan’s historical development. Areas with the highest FAR tend to be commercial areas with daytime office workers and commuters. The left map shows the daytime population density of the over two million commuters. The areas with highest worker density neatly map onto the same areas of Lower Manhattan and Midtown with skyscraper clusters (i.e. high FAR). The right map shows nighttime population density of residential areas, which also neatly map onto areas with generally lower building height and density (i.e. low FAR). Notice the gray-colored zones in Lower Manhattan and Midtown with an almost zero nighttime population density, which are incidentally the areas with the highest daytime population density and the tallest buildings.
In twenty-first-century New York City, it is quite easy to examine the relationship between these three factors – street network, population density, and FAR – as the datasets are readily available from NYC Open Data. Yet, this all becomes more difficult – perhaps prohibitively difficult – for historical mapping. Calculating FAR for historical Manhattan is certainly possible through scrutinizing digitized historical Sanborn fire insurance maps that go so far as to specify building footprint, materials, and height. However, at the moment, this data is not easily accessible. Historical building footprints and FAR must be calculated through manually scanning, tracing, and inputting data from the New York Public Library’s collection. This must be done for thousands (even millions of buildings) over hundreds of years.
As technology improves, it may be possible in a few decades to translate historical maps into data files that reveal FAR. If historical maps could be scanned and immediately transformed from image files to geospatial data files, the possibilities of using historical maps to inform contemporary research are endless. If and when there is the data on historical FAR, it may be possible to create a new paradigm for studying urban history.

Abstract

Prison Floor Plan in 1836

In the contemporary imagination of prison, solitary confinement evokes images of neglect, torture, and loneliness, likely to culminate in insanity. However, the practice originated in the late eighteenth- and early nineteenth-century as an enlightened approach and architectural mechanism for extracting feelings of redemption from convicts.
This research examines the design of Eastern State Penitentiary, built by English-born architect John Haviland from 1821 to 1829 in Philadelphia, Pennsylvania. This case study explores the builders’ challenge of finding an architectural form suitable to the operations and moral ambitions of solitary confinement. Inspired by Jeremy Bentham’s panopticon, Haviland’s design inspired the design of over 300 prisons worldwide. With reference to primary sources and to philosophers Jeremy Bentham and Michel Foucault, this research interrogates the problematic assumptions about architecture and human nature encoded in the form of solitary confinement practiced at Eastern State Penitentiary, which has wider implications for the study of surveillance architecture.

NYC Coronavirus Tour

This NYC tour follows the route of Kenneth T. Jackson’s night tour. As a Columbia University undergraduate, I joined Jackson’s 2016 night tour of NYC by bike, from Harlem, down the spine of Manhattan, and over the bridge to Brooklyn.
With a heavy heart, I gathered my courage on 30 March 2020 to revisit my beloved NYC, along this same route in the now sleeping city attacked by an invisible pathogen. The empty streets hit me with emotions in the misty and rainy weather – perhaps fitting for the city’s low morale.

Eastern State Penitentiary was completed in 1829 in northwest Philadelphia, Pennsylvania by architect John Haviland. It was reportedly the most expensive and largest structure yet built in America.
The design featured a central guard tower from which seven cell blocks radiated like a star. This system allowed a single guard to survey all prisoners in one sweep of the eye. A square perimeter wall surrounded the entire complex – thirty feet high and twelve feet thick. The decorative entrance resembled a medieval castle, to strike fear of prison into those passing. This castle contained the prison administration, hospital, and warden’s apartment.
As we approach the central tower, we see two kinds of cells. The first three cell blocks were one story. The last four cell blocks were two stories. Here we see the view from the guard tower, over the cell block roofs and over the exercise yards between. Each cell had running water, heating, and space for the prisoner to work. Several hundred prisoners lived in absolute solitary confinement. A vaulted and cathedral-like corridor ran down the middle of each cell block. The cells on either side were stacked one above the other. Cells on the lower floor had individual exercise yards, for use one hour per day. John Haviland was inspired by Jeremy Bentham’s panopticon. (Don’t know what the panopticon is? Click here for my explanation.)
Over its century in use, thousands visited and admired this design. An estimated 300 prisons around the world follow this model – making Eastern State the most influential prison ever designed.

Research Paper

When visiting Eastern State Penitentiary in Philadelphia, author Alexis de Tocqueville remarked in his 1831 report to the French government on the state of American prisons:
This Penitentiary is the only edifice in this country, which is calculated to convey to our citizens the external appearance of those magnificent and picturesque castles of the middle ages, which contribute so eminently to embellish the scenery of Europe. [1]
This penitentiary was, at its 1829 opening, the most expensive and largest structure ever built in the United States. Costing $432,000, this building covered a square area 670 feet to a side with walls 30-feet-high by 12-feet-thick and 23-feet-deep at the foundations. Inside, there was: “an entire seclusion of convicts from society and from one another, as that, during the period of their confinement, no one shall see or hear, or be seen or heard by any human being, except the jailor.”[2] About 400 prisoners were equipped with running water, steam heating, individual exercise yards, and (later) gas lighting.[3] These were “luxuries” that newspapers claimed not even the city’s wealthiest citizens could afford, and in an era when the U.S. White House lacked internal plumbing. The Register of Pennsylvania described in February 1830:
The rooms are larger, viz. containing more cubic feet of air, or space, than a great number of the apartments occupied by industrious mechanics in our city; and if we consider that two or more of the latter frequently work or sleep in the same chamber, they have much less room than will be allotted to the convicts [who live one to a room and] whose cells, moreover will be more perfectly ventilated than many of the largest apartments of our opulent citizens.[4]
Given the modern standards of service, technology, and location of this prison, it seems an odd choice to employ the external appearance of a medieval castle. American society lacked the medieval heritage of “old Europe.” The external castle appearance looked to history, while the internal facilities and technology all spoke of a modern future. Robin Evans explained the frequent use of castle imagery as follows: “It was the idea of the prison, not the fact of the prison, that was to engage the architect’s imagination, and the idea of the prison was built up from historical associations.”[5]
Of the several thousand visitors, tourists, and school children who passed through this attraction and the millions more who merely saw it from a distance, the imposing castle appearance was inescapable. In 1866, 76,000 visited, a large number considering more people visited as tourists than as prisoners.[6] In this same era: “The governments of Great Britain, France, Russia, and Belgium, followed each other in quick succession in these missions; and the printed official reports was subsequently issued, accompanied as they were by illustrative drawings, spread through Europe the fame of what was then generally regarded as a remarkable example of reform.”[7] Architect John Haviland (1792-1852) – known to contemporaries as the “jailor to the world”[8] – was a neo-classical architect by training and designed few other Gothic buildings over his 40-year career.[9] He intended these medieval battlements, narrow-slit windows, and portcullis gates to “strike fear into those who passed,” an instructive lesson to those contemplating a career in crime. Unexpected still is the fact that half the $432,000 construction cost was spent on the semi-decorative perimeter wall and external ornament, features not linked to reforming felons within and, in fact, invisible to the felons.[10] Yet, according to de Tocqueville, “It is of all prisons that which requires least a high enclosing wall, because each prisoner is isolated in his cell, which he never leaves.”[11] Why were Philadelphia’s political leaders and prison reformers so concerned with keeping up appearances?
This essay will present reasons for employing medieval imagery. Through analyzing the secular, cultural, and political reasons for this choice of style, we can understand the moral and educational agenda embedded in Eastern State’s appearance.[12] By analyzing the appearance and practice of solitary confinement taken here from 1829 to 1877, we can, by extension, understand more about the hundreds of radial prisons derived from Eastern State.

The Berlin Evolution Animation

Abstract: The Berlin Evolution Animation visualizes the development of this city’s street network and infrastructure from 1415 to the present-day, using an overlay of historic maps. The resulting short film presents a series of 17 “cartographic snapshots” of the urban area at intervals of every 30-40 years. This process highlights Berlin’s urban development over 600 years, the rapid explosion of industry and population in the 19th century, followed by the destruction and violence of two world wars and then the Cold War on Berlin’s urban fabric.

Animation der Wandlung Berlins

Zusammenfassung: Auf der Grundlage von historischen Karten visualisiert die „Animation der Wandelung Berlins“ die Entwicklung des Straßennetzwerks und der Infrastruktur Berlins von 1415 bis heute. In diesem kurzen Video wird eine Serie von 17 „kartographischen Momentaufnahmen“ der Stadt in einem Intervall von 30 – 40 Jahren präsentiert. Dadurch wird die Entwicklung der Stadt Berlin über 600 Jahre, das rapide Wachstum der Industrie und Bevölkerung im 19. Jahrhundert, die Zerstörung und Gewalt der zwei Weltkriege und abschließend des Kalten Krieges auf Berlins Stadtbild verdeutlicht.

Methodology and Sources

I chose not to represent urban development before 1415 for three reasons: Firstly, there are too few accurate maps of the city before this time. Secondly, I needed to find accurate maps that had visual style consistent with later years, to enable easier comparison of development over time. Thirdly, the extent of urban development and population is limited (fewer than 10,000 Berliners).
There are numerous maps showing Berlin’s urban growth. Yet, few of them are drawn to the same scale, orientation and color palette. This makes it more difficult to observe changes to the city form over time. Fortunately, three map resources show this development with consistent style.
  1. The Historischer Atlas von Berlin (by Johann Marius Friedrich Schmidt) published 1835 represents Berlin in the selected years of: 1415, 1648, 1688, 1720, 1740, 1786. This atlas is available, free to view and download, at this link.
  2. After the year 1786, I rely on three books from cartographer Gerd Gauglitz:
    Berlin – Geschichte des Stadtgebietsin vier Karten
    Contains four beautiful maps of Berlin from 1806, 1920, 1988 and 2020. Read article.
    Berlin – Vier Stadtpläne im Vergleich
    Contains four maps from 1742, 1875, 1932 and 2017. Read article.
    Berlin – Vier Stadtpläne im VergleichErgänzungspläne
    Contains four maps from 1840,1953, 1988 and 1950. The last map from 1950 is purely speculative and shows Berlin as it would have looked had Germany won WWII and executed Albert Speer’s plans for rebuilding the city, named “Germania.” Read article.
    Gerd Gaulitz’s three map books can be purchased from Schropp Land & Karte.
  3. I also show the estimated extent of WWII bomb damage to Berlin. This map is sourced from an infographic dated 8 May 2015 in the Berliner Morgenpost. View original infographic. This infographic is, in turn, based on bombing maps produced by the British Royal Air Force during WWII (and Albert Speer’s c.1950 plan for Berlin).
Below is an interactive map I created of the Berlin Wall’s route and the four Allied occupation areas:

Population statistics in the 17 “cartographic snapshots” are estimates. The historical development of Berlin’s population is known for a few years. For other years, the population is estimated with regards to the two censuses between which the year of the “snapshot” falls.

New York City Water Supply Animated History

Developed with Gergely Baics, urban historian at Barnard College

.

New York City has some of the world’s cleanest drinking water. It is one of only a few American cities (and among those cities the largest) to supply completely unfiltered drinking water to nine million people. This system collects water from around 2,000 square miles of forest and farms in Upstate New York, transports this water in up to 125 miles of buried aqueducts, and delivers one billion gallons per day, enough to fill a cube ~300 feet to a side, or the volume of the Empire State Building. This is one of America’s largest and most ambitious infrastructure projects. It remains, however, largely invisible and taken for granted. When they drink a glass of water or wash their hands, few New Yorkers remind themselves of this marvel in civil engineering they benefit from.
This animated map illustrates the visual history of this important American infrastructure.

Sound of water and ambient music from Freesound

New York City is surrounded by saltwater and has few sources of natural freshwater. From the early days, settlers dug wells and used local streams. As the population grew, these sources became polluted. Water shortages allowed disease and fire to threaten the city’s future. In response, city leaders looked north, to the undeveloped forests and rivers of Upstate New York. This began the 200-year-long search for clean water for the growing city.

Interactive Map

I created this animation with information from New York City Open Data about the construction and location of water supply infrastructure. Aqueduct routes are traced from publicly-available satellite imagery and old maps in NYPL map archives. Thanks is also due to Juan F. Martinez, who created this visualization.

For such an important and public infrastructure, the data about this water supply, aqueduct routes, and pumping stations is kept surprisingly secret in a post 9/11 world. However, the data presented here is extracted from publicly-available sources online, and through analysis of visible infrastructure features on satellite imagery when actual vector file data or raster maps are unavailable from NYC government.

What’s wrong with Jeremy Bentham’s Panopticon?

Postmodernist thinkers, like Michel Foucault, interpret Jeremy Bentham’s panopticon, invented c.1790, as a symbol for surveillance and the modern surveillance state.
This lecture is in two parts. I present a computer model of the panopticon, built according to Bentham’s instructions. I then identify design problems with the panopticon and with the symbolism people often give it.
