Time-lapse Animation of Triangle Shirtwaist Factory Fire

  21 May 2023 , , , ,

This animation reconstructs the exact conditions of the workplace, the locations of each fallen body, and the progress of the 1911 fire minute by minute. It is in an accurate-to-the-inch virtual reality model based on trial records, police reports, original measured plans, and primary sources.

.

Pauline Newman letter from May 1951, 6036/008, International Ladies’ Garment Workers’ Union Archives. Cornell University, Kheel Center for Labor-Management Documentation and Archives.

.

The Triangle Shirtwaist Factory fire on Saturday, March 25, 1911 was the deadliest fire in New York City history and one of the deadliest fires in American history. The factory was located on floors eight, nine, and ten of the Asch Building, built in 1901 for various garment sweatshops in Manhattan’s West Village.
To prevent workers from taking unauthorized breaks, to reduce theft, and to block union organizers from entering the factory, the exit doors to the stairwells were locked – a common and legal practice at the time. As a result, more than half of the ninth floor workers could not escape the burning building.
As a result of the fire and lack of workplace protections, 146 garment workers – 123 women and girls and 23 men – died by fire, smoke inhalation, or jumping and falling from the 9th floor windows. Most victims were recent Italian or Jewish immigrant women and girls aged 14 to 23.
After the fire, factory owners Max Blanck and Isaac Harris were not convicted and were ruled “not guilty.” They “compensated” each victim’s family a mere $75. The fire led to news laws requiring fire sprinklers in factories, safety inspections, and improved working conditions. The fire also motivated the growing International Ladies’ Garment Workers’ Union that organized sweatshop workers to fight for a living wage, job protections, and the right to unionize.

Time-lapse History of the United States

  10 December 2022 , ,
This animation visualizes 272,000 data points spanning 220+ years of the U.S. census since 1790. With data from the National Historical Geographic Information System (NHGIS) at the University of Minnesota, I geo-referenced racial dot maps for all ten year intervals since 1790. Overlaying and fading time-lapse cartographies into each other reveals the scale of environmental and urban change.
● Each dot represents 10,000 people.
Top ten largest cities for each decade are labeled in orange.

Musical accompaniment by Philip Glass from the 1982 experimental film Koyaanisqatsi. In the Hopi language of the indigenous peoples of Arizona, the word koyaanisqatsi means “life out of balance.”
As you watch the map, ask:
1. How is the transformation of Indigenous lands into ranches and farmlands made visible in this film?
2. How do immigration and state policies change the built environment? In what ways are immigration and the law visible from the bird’s eye view of this film?
3. How has slavery influenced the demographic landscape and sequential racial dot maps shown in this film?
4. How do changes in transportation technology – in the sequential eras of the canal, the railroad, the highway, the airport, and now the internet – impact how people settle and distribute themselves across the built environment?

Newark Changing: Mapping neighborhood demolition, 1950s to today

  29 June 2022 , , , , ,


Click to launch interactive mapping experience.

.

Newark Changing is a first-of-its-kind visual encyclopedia of 2,400 photo comparisons of almost every street corner​​​, home, and building ​​demolished by urban renewal and the social forces behind urban decay.​ Through an interactive and text-searchable historic map, any visitor can travel in time to explore their street and their building as it appeared in the period 1959-68 vs. today. Thousands of old street photos are brought to life with contemporary 360-degree panoramic photos of the same street scenes today, taken from identical camera angles to the old photos. This is the most extensive collection of photo comparisons past and present ever assembled for any American city.
Newark Changing reveals the scale and devastation of urban renewal, not from the aerial perspective of the city planner’s map but from the human perspective of the street corner and neighborhood. Tens of thousands of individual streets, homes, apartments, churches, and Jewish, Black, and Italian-owned businesses in Newark were “redlined” in the 1930s and deprived of investment. Most of these neighborhoods today have been bulldozed for interstate highways, universities, hospitals, and corporate investments in real estate. Billions in taxpayer money (adjusted for today’s value with inflation) was spent in the period 1945 to 1967 to demolish at least 10,000 buildings, displacing 50,000 people, 65-77% of whom were Black. At the same time, the migration of people and jobs away from urban centers deprived cities like Newark of the industrial employment base they once had. Decades after the 1967 rebellion, Newark still struggles to confront and overcome decades of harm inflicted on the city by de-industrialization and population loss to the suburbs.
Street scenes can be browsed by interactive map, by neighborhood, by subject, by street, or by the public institution responsible for demolition. Visitors can thus travel in time to explore today’s empty fields, parking lots, and desolate streetscapes for the vibrant neighborhoods they were before the automobile age.

A park without trees creates a city without history.

  4 June 2022 ,
Harriet Tubman Square has the largest and most impressive collection of old-growth trees in Downtown Newark. The oldest trees are over 100 feet high, four-feet diameter at the trunk, and up to 150 years old. The City of Newark’s current proposal is to cut every single tree in our park. The only historical precedent for this is the 1960s project that killed every tree in Military Park to build the parking garage now buried beneath. Based on details and architectural plans revealed through an Open Public Records Act request, this animation shows what is planned for our park:

.

Read the plans for the park.

Read our analysis of these plans.

.

We cheer for the historic Harriet Tubman Park for a new, prosperous, and most of all just Newark.
However, nobody should even imagine cutting down these 66 century-old trees, oaks, elms, sycamores, all of which represent our history and particularly African-American experience. In America, trees symbolize both freedom and brutal oppression, should any sensible person forget. Unlike any historic treasures – architectural remnants, shriveled old maps, aged documents, or battled artifacts – these trees are among our most valuable historic icons, standing tall for our children.
Tubman embodied the notion of reclaiming the symbolism of trees and woods as tools of freedom in the black tradition. In the antebellum America, abolitionists always voiced lyrics about glorious trees that bore the fruit of freedom. Dr. Martin Luther King famously said, “Even if I knew tomorrow the world would go to pieces, I would still plan my apple tree.” Tubman was famous for knowing the terrain of trees, woods, and swamps along her journey to freedom. In Tubman’s biography by Sarah Bradford, the black Moses said, “When I found I had crossed that line, I looked at my hands to see if I was the same person. There was such a glory over everything; the sun came like gold though the trees, and over the fields, and I felt like I was in Heaven.”
On the other hand, Billie Holiday sang about fruits produced by these trees: “Southern trees bear strange fruit/Blood on the leaves and blood at the root/Black bodies swing in the southern breeze/Strange fruit hanging from the poplar trees/ …Here is a strange and bitter crop.” The blood of black men, women, and children who refused to remain silent, and who deserve justice, life, liberty, and love, over the hate that surround them.
Last year, Rutgers Newark restored the history and voices of Frederick Douglass in the Historic James Street Commons. Let us not forget, Douglas also said, “If Americans wished to partake of the tree of knowledge, they would find its fruit bitter as well as sweet.” It is unimaginable that Tubman will allow these venerable trees of knowledge to be annihilated.

Cathedral of Beauvais: Sublime Visions; Thwarted Ambitions; A Sketch

  25 December 2021 , ,
Of all the stories of the greatest Gothic cathedrals, the tale of Beauvais is the most exciting. Construction of the Gothic cathedral began in 1225 at a time of bitter turmoil when France was establishing itself as a nation within its familiar modern geographical bounds. Beauvais, the tallest cathedral in France, was never completed, having endured two major collapses and a series of structural crises that continues to this day. Our Sketchup animation follows this dramatic narrative, allowing the viewer to experience and understand the famous collapse that brought down the upper choir in 1284 as well as the underlying design features that led to that disaster. Particularly intriguing is the visualization of the short-lived crossing tower constructed in the mid-sixteenth century and the rivalry between S-Pierre of Beauvais and Saint Peter’s in Rome.
It is hoped that besides appealing to a general audience of cathedral fans, this movie will be useful in the context of the classroom at high-school and university levels.

Detroit Redlining Map in 1940

  20 November 2021 ,
A data visualization of urban history and racializing space
Created with urban historian Robert Fishman

.

This map illustrates in three layers some of the impacts of a racist government policy called redlining:
  1. The base map shows the extent of street network development, as well as the locations of important industries, institutions, and urban features in 1940.
  2. The population dot map shows the areas where Black and Whites lived in the segregated city.
  3. The redlining map shows the areas where government and banks chose not to invest, and to therefore deprive people living there of homes.
All three features – the physical city, the urban residents, and the urban policy of redlining – are interlinked. By displaying these three features together, previously invisible aspects of urban history become visible in plain site to the public.

Historical Reconstruction of Ford Model T Assembly Line

  9 October 2021 , ,
As featured on Kottke.org
This digital model and film show, for the first time, the entire Model T being assembled from start to finish in a single time-lapse shot of the Ford factory in Highland Park, Michigan. Numerous photos were taken and some films were made in the 1910s and 1920s, but no film from the time tracks the entire car’s assembly from start to finish. There were many types of Model Ts produced, but the specific car shown here is the 1915 Model T Runabout. Watch the film and see as the various car components are hoisted over and bolted into place. Or walk across the factory floor in the virtual reality computer model.

.

The film’s audio replicates the sound of Model T production. The accompanying music at start and end is from the 1936 film Modern Times, where comedian Charlie Chaplin parodies Ford’s assembly line production methods.

Henry Ford did not invent the car, nor he did invent the assembly line to produce the car. For years before Ford, cars were being built in small numbers at local workshops. For centuries before Ford, assembly line production was being used to make all manner of goods like pins, fabrics, and steel. At the same time as Ford, others were making cars and building assembly lines.
Ford was not the first, but his car and moving assembly line were certainly the most successful and memorable. After creating his version of the automobile in 1896, Ford moved workshops first to Mack Avenue and later to Piquette Avenue in Detroit. These first two factories were small-scale structures for limited car production. Only in 1913 at Ford’s third factory at Highland Park did mass-production begin on a truly large scale. As shown in this film, here Ford applied assembly line methods throughout the factory to all aspects of car production.

.

Final Stage of Model T Assembly in Highland Park c.1915, David Kimble’s illustration for National Geographic

.

Between when the first Model T rolled off the assembly line in 1913 and when the fifteen millionth rolled off in 1927, the car’s appearance did not change significantly. The car chassis, motor, and color-scheme in 1927 were almost identical to 1913. Despite variations in the number of seats and exterior of car, the motor and chassis beneath were consistent and unchanging over time. Henry Ford liked it that way to bring down costs and to produce the greatest variety of car types with as few variations as possible to the car’s internal structure.
However, although Ford resisted changes to his car design, he was always redesigning the factory floor and assembly line to produce the greatest number of cars with the least amount of human labor. In this same period from 1913 to 1927, the Highland Park factory was constantly redesigned and expanded. Few records survive of all changes to the factory. However, the 1915 book Ford Methods and the Ford Shops includes detailed plans and photos of the factory at one point in time. Ford was still tinkering with the assembly line, as Model T production had begun just over a year before this book was printed. Within a few months of these photos, assembly line methods had improved once again as Ford redesigned the factory floor shown in this film. Rather than documenting Ford production for all time, this film captures Ford production the way it looked in the months it started.

.

.

After Ford stopped producing Model Ts in 1927, newer models started production at the new and larger factory at River Rouge, where Ford makes cars to this day. The Highland Park factory switched to producing other goods like tractors and later tanks for WWII. Within a few years, production methods had so quickly improved under Ford that Highland Park became too small and obsolete. The factory was largely demolished, and with its demolition the initial appearance of Ford’s first and greatest invention was lost for all time: the moving assembly line.
Some of the factory buildings still stand, and the specific part of the factory shown in this film still exists. But the buildings were all cleared of their original machinery, and the most impressive part of Ford’s invention was not the factory itself but instead the equipment and processes within that factory that are no longer visible. The buildings themselves were simply functional warehouses designed with large open spaces to allow the easy movement of machinery.
The entire complex covered many acres, and the other factories that supplied the Highland Park factory with materials and components created a web of trade that spanned the globe. Instead of filming the entire process, this film focuses on the final and most important stage of production where finished parts from all over the world and factory complex came together for final testing and assembly.

The Privatization of Public Space in Lower Manhattan

  20 April 2021 , , ,

Map created by author in QGIS with planimetric data from NYC Open Data

.

More than a specific threat to New York City, the decades-long erosion of public space is an existential threat to democracy.

About 60% of Lower Manhattan’s surface area is listed as being public in some way, but only about 25% is totally unrestricted to the public in practice.*1

.

New York City – and the world’s wealthiest corporations headquartered in Lower Manhattan – had much to do with inventing and spreading new technologies that influenced the urban form. Construction companies like US Steel at 165 Broadway supplied materials for the highways that sliced through cities. Car companies like Chrysler in Midtown encouraged America’s affair with gasoline. Groups like Chase Bank at 28 Liberty Street supplied home loans for whites-only suburbs. Stores like Woolworth at 233 Broadway helped replace small businesses on main street with one-stop department stories and suburban shopping malls. Above them all, the New York Stock Exchange at 11 Wall Street supervised the twentieth-century migration of wealth and capital from American industrial cities to foreign countries with cheaper labor. These changes might have started with the “titans of industry” perched in Lower Manhattan’s skyscrapers, but highways, cars, home mortgages, shopping malls, and de-industrialization all had consequences for the rest of us. This makes Manhattan the ground zero – and in more ways than just September 11 – to understand the forces shaping the loss of public space.
Over the past century, three forces in Lower Manhattan have been chipping away at the quantity and quality of public space: the car, the corporation, and the police state. Each of these three forces effected Lower Manhattan in particular and the nation at large. Each of these three forces, prompted by changes in technology, reshaped the urban form: 1) the invention of the affordable and mass-produced car that substituted for public transit; 2) the abandonment of cities for suburbs that was enabled by the car and encouraged by corporations; and 3) the invention of surveillance technologies to collect, store, and analyze data collected from public spaces. Each of these three technologies were, in turn, weaponized against the urban form to chip away at spaces that once belonged to society at large but which now belong to a select few. Each force will be analyzed in turn – the car, the corporation, and the police state – to reflect on the impact of each on Lower Manhattan’s urban form.
