The time-lapse history of Manhattan in two minutes

.

This two minute time-lapse reconstructs the 400 year evolution of Lower Manhattan’s skyline. Watch as the city evolves from a small village into a glistening metropolis.
This is also a film about the history of technology. Changing methods of representing urban space influence our perception of time and the city. When New York City was founded, Dutch settlers captured their town’s appearance through seventeenth-century drawings and paintings. As the city grew, people started using printing presses to reproduce images of the city in the eighteenth and nineteenth centuries. In the twentieth century, photographers started capturing their city from above through aerial photos. For the first time, New Yorkers could view the entire city in a single panoramic photo.
In tribute to this long artistic tradition, this film constructs the city as each generation of New Yorkers would have represented it: through the subsequent technologies of drawing, printing, photography, and film.

The image features ~4,493 buildings. For the largest and most important buildings, more attention is paid to detail. All of Manhattan’s bridges and major parks are included. Any buildings excluded were done so because they were either too small, too distant to include, or not visible from the angle this image is taken.

Riding Professor Kenneth Jackson’s all night bike tour through Gotham’s history inspired this image. Traced in orange below is the route of Jackson’s bike tour: starting at Columbia University’s Low Library, through Central Park, across Midtown to Washington Park, along the Hudson River to Wall Street, and then across the Brooklyn Bridge.

What gave me the idea for this project?
My goal in ten years is to research and teach about art history and urban studies. Unfortunately, most aspiring professors do not get to choose the city where they work. Because I might not have the privilege of working near New York City, I wanted to draw a keepsake of all my youthful memories and experiences here. I have a photographic memory walking through the city. So I have memories that relate to all the buildings shown. I plan to frame this on the wall above my desk.

.

What was the most difficult part?
Because the image is ink on paper, there is no way to erase a mistake. At the later stages, any slip of the pen might have destroyed several months of work.
I am delighted with the result, but the process was tedious and required drawing thousands of windows. I never counted how many. I could only work a few hours per day before becoming exhausted. I will never attempt a drawing like this again because it is so time-consuming, and I am unlikely to ever find myself trapped again at home for such a long period of time. Fortunately.

.

Has the current pandemic changed how I think about NYC?
The pandemic is forcing me to appreciate NYC from a distance. Even if I am afraid to ride public transit, this drawing – and the experiences it represents – will always be a part of me.
I can see this pandemic slowing down some gentrification and keeping the built environment similar to my drawing for a good few more years. I am just afraid that, with so many businesses closing, the city might emerge from this pandemic unfamiliar to how I remember it in this drawing.

Here Grows New York City

Music: “The Language of Cities” by Maserati

1. The Animation

Here Grows New York visually animates the development of this city’s street grid and environment from 1609 to the present day, using geo-referenced road network data, historic maps, and geological surveys. The resulting short film presents a series of “cartographic snapshots” of the built-up environment at intervals of every 20 to 30 years in history. This process highlights the organic spurts of growth and movement that typify New York’s and most cities’ development through time. The result is an abstract representation of urbanism.

2. The Interactive Map

The results of this animation are transformed into this fully interactive map

3. Research Method

Several hundred maps in the digital archives of the New York Public Library and Library of Congress were analyzed to assemble this film. About 25 of these maps were then selected, downloaded, merged, stretched, and warped in a single document to align with each other. This provided a consistent scale and allowed easier comparison of differences between maps of different date. As the source files were all in different colors, scales, and designs, we created a single base map with unified graphics. The redrawing not only permits correcting errors in less accurate old maps but also provides a graphic representation that is consistent over time. This coherence allows the rate and trends in urban growth to be read more easily and compared between eras.

4. Conclusions and Analysis

This data visualization informs our analysis of the history of the New York City grid. This analysis reflects on the question: What can the built environment of Manhattan’s streets reflect about the evolving social and economic priorities of city planners and leaders? The long phases of urban growth and shifting transportation modes created distinctive road networks in Manhattan. The predominance of different forms of transport during each era also prompted changes to the location and dimensions of streets in response. Manhattan illustrates the evolution of these road networks over four centuries of near continuous growth. A plot can describe a street grid, as well as its builders’ story. This paper aims to tell this second plot, a story of urbanism.

5. Credits and Appendix

This project would not have been possible without the support, mentorship, and patience of my parents, Anne Mabry and Zemin Zemin Zhang. Nor would this project have been possible without the historical expertise of Columbia University professors Kenneth T. Jackson (History Department) and Gergely Baics (Urban Studies). Thanks is also extended to those who reviewed and critiqued this project in its early stages, including Chris Kok, Wright Kennedy, Dan Miller, and the Center for Spatial Research at Columbia’s Department of History. Most importantly, I thank my dog ChoiChoi.

Model of Jane’s Carousel in Brooklyn

.

A wind-up music box featuring Jane’s Carousel along the Brooklyn Waterfront. When closed, the antique cigar box measures a mere 7 by 7 inches and 3 inches deep. When opened, the Brooklyn Bridge and historic Jane’s Carousel fold out. The carousel spins to the tune of the music while the moon slides across the night sky.
Materials: $4 cigar box, $5 wind-up music box, electrical wire (for trees), plastic lids for wheels, string, tape measure, tin foil, and thick paper

Pictures of Newark

.

As a lifelong citizen of Newark, I spent much of the past few years painting and photographing my changing city. Pictures features a selection of my work, complemented by classical music. Five of Modest Mussorgsky’s pieces from his composition Pictures at an Exhibition are selected, each of which represents the feel of a certain part of Newark. The following five locations are featured:
1. THE PASSAIC RIVER – music: Mussorgsky’s Promenade
2. OLD ESSEX COUNTY JAIL – music: With the Dead in the Language of Death
3. MOUNT PLEASANT CEMETERY – music: Promenade
4. DOWNTOWN NEWARK – music: Mozart’s Death March (k 453a)
5. PORT NEWARK – music: Promenade
Growing up in Newark, I am inspired and saddened by the inner city. I am inspired by Newark’s hope of renewal after decades of white flight, under-investment, and urban neglect. I am saddened by the loss of my city’s historic architecture and urban fabric to the wrecking ball of what is called progress.

Port Newark

.

Port Newark is America’s largest port on the Atlantic coast. On weekdays, hundreds of cargo ships deliver thousands of Chinese-made products to waiting trucks and trains. On weekends, the port is empty of life, an unintentional and empty urban monument to America’s economic might.

Pulaski Skyway

When I left home to attend Columbia University, I knew the transition to college would leave me homesick for Newark. To remind me of home, I painted this watercolor panorama. Every night, in my dorm room, I gazed at this painting and traced the streets and buildings of my childhood memories.

New Jersey Meadowlands

The New Jersey Meadowlands, nestled between New York City and Newark, is a strange sort of in-between zone. It belongs neither to nature nor to man. The grasslands and birds of nature are abundant. So, too, are the derelict factories and warehouses. The unwanted detritus of civilization is cast off into the Meadowlands, ranging from garbage piles to noxious-smelling industries.
Millions of commuters to and from the suburbs to New York City pass through this region of indeterminate identity. Many look out the windows of passing trains, planes, and cars. Yet few care to observe the lapping tides and bizarre beauty of this unwanted strip of land. These views show various scenes from my daily train ride through the Meadowlands between Newark Broad Street and Hoboken Terminal.
