Jersey City: Urban Planning in Historical Perspective
A booklet about the history of the master plan

Over its four-century history, the evolution of Jersey City mirrors the larger history of the New York region. Each generation of Jersey City residents and political leaders have faced different urban challenges, from affordable housing, to clean water, to air pollution, and income inequality. Each generation has responded through the tools of city planning and the master plan.
Jersey City’s six master plans – dated 1912, 1920, 1951, 1966, 1982, and 2000 – capture the city at six historical moments. Reading these plans and comparing them to each other is a lens to understand urban history, and American history more broadly.

.

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.

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

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.

Historical Reconstruction of Ford Model T Assembly Line

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.

.

.

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 Meaning of Notre-Dame

The construction of Notre-Dame mirrors the larger story of the French nation.
Medieval France was splintered into regional kingdoms and alliances between local feudal lords. In the tenth century, the Capetian rulers in central France started consolidating power and lands. Through conquest, marriage, and diplomacy, the Capetians expanded their influence first to Paris and then outward. By the thirteenth century, the Capetians controlled most of the land within the present-day borders of what is now France. Over this Catholic kingdom, they ruled generation after generation in centuries of uninterrupted rule until the French Revolution.
While the Capetians did not start as the largest and most powerful kingdom in Europe, they soon amplified their power through alliance with the church. From Reims Cathedral (where all Capetians were crowned) to the Church of St. Denis near Paris (where they were all buried), the French monarchs asserted power through their relationship with the church. They claimed their right to rule descended from God’s mandate. God himself ruled through and expressed his demands through the soul and mind of the king. To oppose the king would therefore be to oppose the wishes of God.
The construction of Notre-Dame of Paris was therefore a project for the Capetian kingdom in the capital city of Paris. With the monarchy’s control of France’s largest and most important trade center, the cathedral became a central symbol of the power of the city and the kingdom. From across Europe and France, other peoples looked to Notre-Dame for design inspiration. The model and building techniques of Notre-Dame were copied far and wide. Paris might have had limited geographic borders, but through the churches and monasteries in other regions that looked to Paris for aesthetic inspiration and theological guidance, Paris wielded a soft power to influence culture.

.

Among medieval cathedrals known to take centuries to complete, Notre-Dame was finished in short time. In just eight decades from c.1160 to c.1245, Notre-Dame emerged from the rubble in the completed form the public would recognize it today. Soon, neighboring towns in competition with Paris began erecting larger and taller cathedrals of their own. Among them, the powers centered on the cities of Chartres to the southwest, Amiens to the north, and Rouen to the northwest expressed their competition with Paris through their grander cathedrals. Not to be outdone, from 1220 to 1225 the Parisians rebuilt the entire upper levels and vaults of Notre-Dame to be taller, more luminous, and more ornate than before. The powers at Chartres, Amiens, and Rouen were soon crushed in battle and became the allies of an increasingly centralized French empire.
The public interprets cathedral construction as an act of devotion to God. The fine materials, craftsmanship, and physical challenges of construction symbolize the builders’ devotion, or gratitude for God listening to their prayers. The more expensive the project and the more difficult the construction, the greater the finished cathedral becomes as a symbol of sacrifice. Medieval stories often speak of the devout paying penance for their sins by dragging carts of heavy cathedral stones from quarry to building site. Or when the cathedrals faced structural collapse, natural disasters, and frequent fires, builders and clergy read these events as God expressing his dissatisfaction that their project was not good enough.
Less often does the public see the sacred built environment as an expression of political power, or as a tool of diplomacy and nation building. For the church to somehow be caught up in earthly affairs of wealth building, land investments, tax collection, and power squabbles seems vulgar and a distraction from the higher sacred mission. Cathedral construction required massive fundraising and tax collection efforts, the mobilization of thousands of laborers, and the sale of indulgences (donations to the church in exchange for certificates promising to reduce the donor’s punishment in the afterlife). As Notre-Dame of Paris reveals, construction cannot be separated from larger political events.
At every step in the history of the Capetians, monarchs sponsored building projects and used their power to carry out the political agenda of the church. Louis IX was made a saint for leading the Crusades to retake the Holy Land and its trade routes from Islam. The Sun King Louis XIV relied on the papal Cardinal Mazarin during his earliest years in power. And the ill-fated Louis XVI refused to share the monarchy and church’s monopoly on power with the people, causing the middle and working classes to wage the French Revolution.
The French Revolution asserted that government’s right to rule does not descend down from God and the church, as monarchs had claimed for centuries. Instead, political legitimacy flows up from the people, their right to vote, and their support for the elected government. Skepticism in the religious basis for political power, coupled with the Enlightenment belief that science and human reason alone can unlock social progress and the project of democracy, re-centered society on a new foundation. Church and state were separated, and with that Notre-Dame fell into a half-century of decay and abandonment.
In the French Revolution, Notre-Dame and hundreds of other French churches were abandoned, desecrated, and often demolished for the value of their building materials. Notre-Dame was confiscated from the church and transformed into a “Temple of Reason,” while most of its statuary was destroyed. The statues of 28 Biblical kings on Notre-Dame’s west façade were mistaken as French because their robes were modeled after Capetian kings. And so they were pulled down with ropes and decapitated by the mob in the city square. Not until the mid nineteenth century was Notre-Dame restored by Viollet-le-Duc with a new spire, new windows, new carvings, and restoration efforts sometimes so extensive that the cathedral surviving today is as much a product of the medieval era as it is a nineteenth-century creation. Notre-Dame began to emerge as a symbol of the French culture, identity, and nation.
Notre-Dame’s fire on 15 April 2019 reminded the public once again of architecture’s role in shaping and symbolizing national identity. The fire was as much a loss of architecture and cultural heritage as it was a threat to the French identity. The cathedral’s fire-damaged vaults and wooden roof turned to ashes symbolized an interrupted continuity with history. The cathedral had survived hundreds of years through plague, world wars, and revolution, as if symbolizing the continuity and purity of the French language, culture, and history. And now this link with history and the origins of the modern French nation was severed.
The efforts to rebuild Notre-Dame “as it was before” reveal the larger misconception that there is such a thing as a pure and original state. Pre-modern builders and patrons interpreted fires and natural disasters as innovation opportunities to rebuild what was lost as bigger and better than before, and often with the latest building techniques and architectural style. The church that stood at the site of future Notre-Dame, and which was demolished to build the current cathedral, was itself hundreds of years old and dating back to the late Roman Empire. And yet medieval audiences demolished it all the same with the confidence that what they built would be better than what was there before. Past generations at Notre-Dame viewed the cathedral and history as something fluid that could be embellished and improved through cycles of demolition. As late as the nineteenth century, Viollet-le-Duc imagined and added new details to the cathedral that never, in fact, existed.
Just days after the fire, architects submitted dozens of proposals to rebuild the site. Preservationists instead decided to rebuild the cathedral with the same pre-modern techniques, materials, and interior wooden roof trusses. Is contemporary art and culture so impoverished of beauty that contemporary society is incapable of enriching Notre-Dame with the building techniques and aesthetics of the modern era? Do we no longer believe in the forward path of progress, and must therefore pause the appearance of Notre-Dame the way it was?
The fire revealed that there are, in fact, two cathedrals: the physical cathedral built as a symbol of the French state and faith; and then the cathedral of our memories, with all the personal meanings visitors drew from their experience of the space. The two cathedrals are not the same because the meanings and symbolism we assign Notre-Dame in our memories are different from the cathedral’s intended purpose. The medieval clergy and kings never intended to create a symbol of the modern French state, of Victor Hugo’s literature, or of international Christianity. Yet Notre-Dame’s ability to acquire new meanings and identities through time speaks to the fact that this cathedral is a living work of art. With or without the physical cathedral, the Notre-Dame of our imaginations, of art, of literature, and of the millions of souvenir photographs will continue to live. At least in the collective imagination, Notre-Dame is immortal.

This construction time-lapse illustrates the history of Notre-Dame from c.1060 to the present day, following ten centuries of construction and reconstruction. Model is based on actual measurements of the cathedral and was peer reviewed for accuracy by scholars at Columbia University’s art history department and at the Friends of Notre-Dame of Paris.
The film was created in the computer modeling software SketchUp, based on hand-drawn image textures. The ink drawings of nineteenth-century architect Viollet-le-Duc were scanned and applied to the model surfaces, so as to transform the two-dimensional artwork into the three-dimensional digital. I believe computer models should preserve a certain handmade quality.

St. Paul’s Cathedral Dome: a synthesis of engineering and art

Developed with James Campbell, architectural historian at the University of Cambridge
Inspired by taking George Deodatis’ lectures on The Art of Structural Design
at Columbia University’s Department of Civil Engineering

.

In 1872, Eugène-Emmanuel Viollet-le-Duc, the French author and architect celebrated for restoring Notre-Dame of Paris, wrote in his Lectures on Architecture that the form of the Gothic cathedral was the synthesis of the early Christian basilica and the Romanesque three-aisled church. In this analysis, Viollet-le-Duc reasoned that a thesis (early Christian) plus an antithesis (Romanesque) produced the synthesis (Gothic).

.

Animation from Stephen Murray

Although the history and origins of Gothic are more complex than Viollet-le-Duc’s formula, this formula provides a method to dissect the Renaissance and Enlightenment counterpart to the medieval cathedral: the Greco-Roman basilica, as embodied by St. Paul’s Cathedral, constructed from 1675 to 1711 by Christopher Wren (1632-1723). St Paul’s is a symbol of Enlightenment-era London, built to rival its medieval counterpart of Westminster Abbey.
In this essay, and in my analysis of this neoclassical cathedral, I will parallel Viollet-le-Duc’s analysis of the medieval church. The thesis is that St. Paul’s is a work of techno-scientific engineering. The antithesis is that this building is a work of art that speaks to the larger cultural moment of Enlightenment London. The synthesis is the dome of St. Paul’s that merges these two forces of engineering and art into a unified and impressive creation.

Music from the organ (William Tell’s Overture) and bells of St Paul’s (recorded 2013)

.

St. Paul’s Cathedral features an innovative triple dome structure. On the circular drum, the inner dome rises and is visible from the cathedral interior. Above this inner dome, a brick cone rises to support the 850 ton lantern. This brick cone also supports the wood rafters and frame of the outer dome, which is covered in wood and lead. This three dome system allows the cathedral to support such a heavy lantern, all the while maintaining the great height needed to be a visible London landmark.
  • Inner dome – visible from inside and purely for show; height 225 ft (69m)
  • Middle brick cone – a brick cone that is invisible from below but supports the 850 ton lantern above; height 278 ft (85m)
  • Outer dome – a wood and lead-roofed structure visible from the cathedral exterior; height 278 ft (85m)
  • Lantern – an 850 ton stone lantern and cross, whose weight is carried to the ground via the middle brick cone 365ft (111m)
The inner and outer domes are decorative, while the brick cone is the true weight-bearing support. The model below is created from measured plans and is accurate to reality.
