Eastern State Penitentiary was completed in 1829 in northwest Philadelphia, Pennsylvania by architect John Haviland. It was reported as 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 cell blocks. 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

Eastern State Penitentiary’s exterior resembles a medieval castle. More than a random choice, the qualities of Gothic attempt to reflect, or fall short of reflecting, the practices of detention and isolation within. Contrary to the claim often made about this structure that the appearance was supposed to strike fear into passerby, the use of Gothic is in many ways unexpected because of its untoward associations with darkness and torture, which the prison’s founders were working to abolish. It is therefore surprising that America’s largest and most modern prison should evoke the cruelties and injustices of the medieval period. The choice of Gothic appearance, and the vast funds expended on the external appearance few inmates would have seen, leads one to question the audience of viewers this penitentiary was intended for – the inmates within or the public at large?
This essay responds by analyzing what the Gothic style represented to the founders. The architectural evocation of cruelty and oppression was, in fact, not contradictory with the builders’ progressive intentions of reforming and educating inmates. This prison’s appearance complicates our understanding of confinement’s purpose in society. The two audiences of convicted inmates and tourist visitors would have received and experienced this prison differently, thereby arriving at alternative, even divergent, understandings of what this prison meant. More than an analysis of the architect John Haviland and of the building’s formal qualities in isolation, this essay situates this prison in the larger context of Philadelphia’s built environment.

The Berlin Evolution Animation

  31 January 2020 , ,
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 nineteenth-century, followed by the destruction and violence of two world wars and then the Cold War on Berlin’s urban fabric.

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 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 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

  23 December 2019 , ,
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 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, 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.

Computer Model of Jeremy Bentham’s Panopticon

  11 November 2019 , , ,
Created at the University of Cambridge: Department of Architecture
As part of my Master’s thesis in Architecture and Urban Studies, as featured by:
– Special Collections department at University College London
– Open Culture
– Aeon: a world of ideas
.
To say all in one word, it [the panopticon] will be found applicable, I think, without exception, to all establishments whatsoever, in which, within a space not too large to be covered or commanded by buildings, a number of persons are meant to be kept under inspection.
– Jeremy Bentham
.

.

Since the 1790s, Jeremy Bentham’s panopticon remains an influential building and representation of power relations. Yet no structure was ever built to the exact dimensions Bentham indicates in his panopticon letters. Seeking to translate Bentham into the digital age, I followed his directions and descriptions to construct an exact model in virtual reality. What would this building have looked like if it were built? Would it have been as all-seeing and all-powerful as Bentham claims?
Explore Bentham’s panopticon in the animation above or in virtual reality below
based on Bentham’s drawings at University College London:

Panopticon: Theory vs. Reality

Central to Bentham’s proposed building was a hierarchy of: (1) the principal guard and his family; (2) the assisting superintendents; and (3) the hundreds of inmates. The hierarchy between them mapped onto the building’s design. The panopticon thus became a spatial and visual representation of the prison’s power relations. As architectural historian Robin Evans describes: “Thus a hierarchy of three stages was designed for, a secular simile of God, angels and man.”

To his credit, Bentham recognized that an inspector on the ground floor could not see all inmates on the upper floors. The angle of view was too steep and obstructed by stairs and walkways. To this end, Bentham proposed that a covered inspection gallery be erected between every two floors of cells.
By proposing these three inspection galleries, Bentham addressed the problem of inspecting all inmates. However, he created a new problem: From no central point was it now be possible to see all activity, as the floor plans below show. The panoramic view below shows the superintendent’s actual field of view, from which he could see into no more than four complete cells at a time. The view from the center was not, in fact, all-seeing. Guards would have to walk a continuous circuit round-and-round, as if on a treadmill. They, too, are prisoners to the architecture.

.

The intervening stairwells and inspection corridors between the perimeter cells and the central tower might have allowed inspectors to see into the cells. Yet these same architectural features would also have impeded the inmates’ view toward the central rotunda. Bentham claimed this rotunda could become a chapel, and that inmates could hear the sermon and view the religious ceremonies without ever needing to leave their cells. The blinds, normally closed, could be opened up for viewing the chapel.

.

.

Bentham’s suggestion was problematic. The two cross sections above show that, although some of the inmates could see the chapel from their cells, most would be unable to do so.
In spite of all these obvious faults in panopticon design, Bentham still claimed that all inmates and activities were visible and controlled from a single central point. When the superintendent or visitor arrives, no sooner is he announced that “the whole scene opens instantaneously to his view,” Bentham wrote.

.

View from guard tower to cells: VISIBILITY
View from cells to guard tower: INVISIBILITY

.

Despite Bentham’s claims to have invented a perfect and all-powerful building, the real panopticon would have been flawed were it built as this data visualization helps illustrate. Although the circular form with central tower was chosen to facilitate easier surveillance, the realities and details of this design illustrate that constant surveillance was not possible. That the British public and Parliament rejected Bentham’s twenty year effort to build a real panopticon should be no surprise.
However flawed the architecture, Bentham remained ahead of his time. He envisioned an idealistic and rational, even utopian, surveillance society. Without the necessary (digital) technology to create this society, Bentham fell back on architecture to make this society possible. The failure of this architecture and its obvious shortcomings do not invalidate Bentham’s project. Instead, these flaws with architecture indicate that Bentham envisioned an institution and society that would only become possible through new technologies invented hundreds of years later.

New York City in a Box

  21 July 2019 , ,
As featured in this article from Live Auctioneers

.

.

.

Inspired by the Stettheimer Dollhouse at the Museum of the City of New York, this pop up model in a recycled metal box (measuring 8 inches wide by 15.5 long and 2.5 deep) reveals a miniature world of New York City architecture and landmarks within. About 30 buildings made from hand cut paper and tin are spread across a flat ground of painted streets. Each building is made from a single sheet of paper that is cut and folded like origami to create different shapes and sizes. A hand cranked lever operates a mechanism of chains and gears hidden beneath the  paper surface of the city streets. These gears move the magnetized trains and airplanes through the city.

California Waterscape: time-lapse history of water supply

  15 June 2019 , ,
California Waterscape animates the development of this state’s water delivery infrastructure from 1913 to 2019, using geo-referenced aqueduct route data, land use maps, and statistics on reservoir capacity. The resulting film presents a series of “cartographic snapshots” of every year since the opening of the Los Angeles Aqueduct in 1913. This process visualizes the rapid growth of this state’s population, cities, agriculture, and water needs.

.

Music: Panning the Sands by Patrick O’Hearn

Dams and Reservoirs

^ Created with open data from the US Bureau of Transportation Statistics and visualized in Tableau Public. This map includes all dams in California that are “50 feet or more in height, or with a normal storage capacity of 5,000 acre-feet or more, or with a maximum storage capacity of 25,000 acre-feet or more.” Dams are georeferenced and sized according to their storage capacity in acre-feet. One acre-foot is the amount required to cover one acre of land to a depth of one foot (equal to 325,851 gallons or 1.233 ● 106 liters). This is the unit of measurement California uses to estimate water availability and use.

.

.

Aqueducts and Canals

^ Created with open data from the California Department of Water Resources, with additional water features manually added in QGIS and visualized in Tableau Public. All data on routes, lengths, and years completed is an estimate. This map includes all the major water infrastructure features; it is not comprehensive of all features.

 

Method and Sources

The most important data sources consulted are listed below:

This map excludes the following categories of aqueducts and canals:

  • Features built and managed by individual farmers and which extend for a length of only a few hundred feet. These features are too small and numerous to map for the entire state and to animate by their date completed. This level of information does not exist or is too difficult to locate.
  • Features built but later abandoned or demolished. This includes no longer extant aqueducts built by Spanish colonists, early American settlers, etc.
  • Features created by deepening, widening, or otherwise expanding the path of an existing and naturally flowing waterway. Many California rivers and streams were dredged and widened to become canals, and many more rivers turned into “canals” remain unlined along their path. Determining the construction date for these semi-natural features is therefore difficult. So, for the purposes of simplicity and to aid viewers in seeing only manmade water features, these water features are excluded.

Since 1971, the old Essex County Jail has sat abandoned and decaying in Newark’s University Heights neighborhood. Expanded in stages since 1837, this jail is among the oldest government structures in Newark and is on the National Register of Historic Places. The building needs investment and a vision for transforming decay into a symbol of urban regeneration. As a youth in Newark, I explored and painted this jail, and therefore feel a personal investment in the history of this place. Few structures in this city reflect the history of racial segregation, immigration, and demographic change as well as this jail.
In spring 2018, a graduate studio at Columbia University’s master’s in historic preservation program documented this structure. Eleven students and two architects recorded the jail’s condition, context, and history. Each student developed a reuse proposal for a museum, public park, housing, or prisoner re-entry and education center. By proposing eleven alternatives, the project transformed a narrative of confinement into a story of regeneration.
Inspired by this academic project and seeking to share it with a larger audience, I and Zemin Zhang proposed to transform the results of this studio into a larger dialogue about the purpose of incarceration. With $15,000 funding from Newark Landmarks, I translated Columbia’s work into an exhibition. I am grateful to Anne Englot and Liz Del Tufo for their help securing space and funding. Over spring 2019, I collaborated with Ellen Quinn and a team at New Jersey City University to design the exhibit panels and to create the corresponding texts and graphics. The opening was held in May 2019, and is recorded here.

.

.

My curator work required translating an academic project into an exhibit with language, graphics, and content accessible to the public. Columbia examined the jail’s architecture and produced numerous measured drawings of the site, but they did not examine social history. As the curator, I shifted the exhibit’s focus from architecture to the jail’s social history – to use the jail as a tool through which to examine Newark’s history of incarceration. As a result, much of my work required supplementing Columbia’s content with additional primary sources – newspaper clippings, prison records, and an oral history project – that tell the human story behind these bars. I worked with local journalist Guy Sterling to interview former jail guards and Newark Mayor Ras Baraka about his father’s experience incarcerated here during the 1967 civil unrest. The exhibit allowed viewers to hear first-hand accounts of prison life and to view what the Essex County Jail looked like in its heyday from the 1920s to 1960s. Rutgers-Newark organized seminars connected to the jail exhibit on the topic of incarceration in America, and what practical steps can be taken to change the effects of the growth of incarceration.
The finished exhibit was on display from May 15 through September 27, 2019. The exhibit makes the case for preserving the buildings and integrating them into the redevelopment of the surrounding area. The hope is that, by presenting this jail’s history in a public space where several thousand people viewed it per week, historians can build support for the jail’s reuse. Over the next year, an architecture studio at the New Jersey Institute of Technology’s College of Architecture and Design is conducting further site studies. Before any work begins, the next immediate step is to remove all debris, trim destructive foliage, and secure the site from trespassers. These actions will buy time while the city government and the other stakeholders determine the logistics of a full-scale redevelopment effort.
My interest in prisons drew me to this project. This jail’s architect was John Haviland, who was a disciple of prison reformers John Howard and Jeremy Bentham. In my MPhil thesis research about Philadelphia’s Eastern State Penitentiary, I developed my exhibit research by looking at the social and historical context of John Haviland and early prisons. As I describe, Eastern State began as a semi-utopian project in the 1830s but devolved by the 1960s into a tool of control social and a symbol of urban unrest.

24 Hours in the London Underground

  21 April 2019 ,

Audio effect: Heartbeat from Freesound

.

Through analyzing 25,440 data points collected from 265 stations, this animation visualizes commuting patterns in the London Underground over two weeks in 2010.
Each colored dot is one underground station. The dots pulsate larger and smaller in mathematical proportion to the number of riders passing through. Big dots for busy stations. Small dots for less busy stations.
Dot color represents the lines serving each station. White dots are for stations where three or more lines intersect. Each dot pulsates twice in a day: Once during the morning commute; and again during the evening commute.
By syncing the audio volume with the density of riders and the background color with the time of day, the animation becomes acoustically legible. The audio volume rises and falls to mirror the growth and contraction of each colored dot during the daily commute.

.

.

The rhythmic pulsing of commuters is analogous to the breathing human body. The passage of red blood cells from the lungs to the organs is analogous to the movement of people to and from the city’s own heart: the downtown commercial district. This analogy of human form to city plan is a longstanding theme in urban studies.
See my film about commuting patterns in the NYC subway.

.

The Data

.

.

Method

No single data set could capture the complexity of a metropolis like London. This animation is based off of open-access data collected in November 2010. According to Transport for London: “Passenger counts collect information about passenger numbers entering and exiting London Underground stations, largely based on the Underground ticketing system gate data.” Excluding London Overground, the Docklands Light Railways, National Rail, and other transport providers, there are 265 London Underground stations surveyed. For data collection purposes, stations where two or more lines intersect are counted as a single data entry. This is to avoid double-counting a single passenger who is just transferring trains in one station en route to their final destination.

Every fifteen minutes, the numbers of passengers entering the system are tallied. This yields 96 time intervals per day (4 x 24). Multiplying the number of time intervals (96) by the number of stations (265), we get the number of data points represented in this animation: 25,440. Each station was assigned:

  • A location on the map of latitude and longitude
  • A color according to the lines extant in 2010: Bakerloo, Central, Circle, District, Hammersmith & City, Jubilee, Metropolitan, Northern, Piccadilly, Victoria, Waterloo & City.
  • A circle scaled to reflect the number of passengers moving through. Stations range in business from a few hundred passengers to over 100,000 per day.
  • A time of day: each 15-minute interval becomes one image in this film. Overlaying these 96 “snapshots” of commuter movement creates  a time-lapse animation. Thus, a single day with 25,440 data points is compressed into a mere 8 seconds.

Northeast Corridor railroad time-lapse

  2 February 2019

Audio effects from Freesound; music is Metamorphosis by Philip Glass

.

The Northeast Corridor is the busiest passenger railroad in North America. This drone flight follows a high-speed Acela train making this 456 mile journey from Washington D.C. to Boston via Baltimore, Wilmington, Philadelphia, Trenton, Newark, New York City, Stamford, New Haven, and Providence.
This animation was created from Google Earth satellite imagery. I traced the Northeast Corridor route onto the ground, and I then programmed the computer to follow this route. I then added the inset map, sound effects, and clock in post-production.

The visual language of data addresses a deeper need to humanize and soften the concrete jungle.

In this animation based on subway ridership statistics by station:
● Dots are color-coded according to the subway lines they serve.
● White dots are for junctions between two or more lines of different color.
● Dot size corresponds to the number of riders entering each station within a 24 hour period.
● Larger dots are for busier stations. Smaller dots are for less busy stations.
Movements through the New York City subway are analogous to rhythmic breathing.
People often describe cities in relation to the human body. Major roads are called “arteries” in reference to blood flow. The sewers are the city’s “bowels” in reference to our own digestive systems. Central Park is the city’s “lungs.” At various times in history, key industries like garments and finance were described as the “backbone” of New York’s economy. Although cities are complex organisms, wordplay makes the giant metropolis somehow more human and familiar.
The 424 subway stations and 665 miles of track are analogous to the human circulatory system. Every weekday pre-coronavirus, the subway carried 5.4 million people, mostly commuters. This daily commute is ordered, structured, and rhythmic – as Manhattan’s population swells during the daily commute and then contracts by night. Each passenger symbolizes the movement of a single red blood cell. With each paycheck, the oxygen of capitalism flows from the heart of Manhattan to the cellular homes in the outer boroughs.
Commuting patterns mirror the rhythmic expansion and contraction of the human body while breathing. By contrasting weekday and weekend ridership patterns, we detect the city’s respiratory system.

Research Method

In this video lecture, I walk you through how I manipulated MTA and NYC open data
to create this animation.

.

The Metropolitan Transit Authority (MTA) publishes statistics on weekday and weekend (Saturday + Sunday) ridership for all 424 stations. These statistics, updated yearly, are public and can be analyzed to track trends in urban growth. I downloaded the MTA data and assigned each station a geographical coordinate (latitude + longitude) so that the data points would appear at their corresponding map locations.

I have a love-hate relationship with the New York City subway. At rush hour, it is crowded, hot, and slow. From years of riding its squeaky trains, it’s given me a ringing tinnitus sound in my ear. Despite its flaws, the subway is one of the few urban spaces where all social classes and ethnicities mix, where their separate lives are momentarily shared. Rich or poor, everyone rides the subway. I hope this animation renews appreciation for this engineering and the people behind it.
