“THE CHICAGO MIRACLE “In 1830 there were probably more pigs than houses in Chicago: its population was about 300.” 1850 population: 29,963 (570.3% increase from 1840) 1860 population: 112,172 (274.4% increase from 1850) 1870 population: 298,977 (166.5% from 1860) 1880 population: 503,185 (68.3% from 1870) 1890 population: 1,099,850 (118.6% increase from 1880) 1900 population: 1,698,575 (54.4% increase from 1890)
As an importer, processer, packager and exporter of goods from all around the United States, Chicago became one of the fastest urbanized cities of the world. 1/25 of the world’s railways converged in Chicago in 1890. It was the most easily reached of the world’s large cities. In 1890 Chicago had two dozen “skyscrapers,” 7,000 offices were functioning and another 7,000 was being planned.
What is the most striking difference between the layouts of Paris and Chicago? What accounts for this difference?
The grid layout, which allows for efficient subdivision of land to be sold and easy expansion. This served the purposes of construction bosses who dominated the building industry.
Great Chicago Fire, 1871 “On October 8, 1871, the Great Chicago Fire destroyed most of the city's central area. It started in the lumber district on the city's West Side. A cow owned by Mrs. O'Leary's allegedly knocked over a kerosene lamp that started the fire. By October 10, the fire had destroyed nearly four square miles of the city, and had claimed at least 250 lives and left 100,000 residents (20%) homeless. More than 17,000 buildings were destroyed and property damages were estimated at $200 million.” The fire showed the vulnerability of cast iron. “The Rush for Life Over the Randolph Street Bridge, 1871” (Harper's Weekly, from a sketch by John R. Chapin) Chicago, 10 October 1871 map of fire damage
“THE SKYSCRAPER” 1855: The “Bessemer Process” becomes the first inexpensive industrial process for the mass-production of steel from iron. (steel = iron + carbon, making it more fire-resistant than iron) 1865: Steel production made even easier and more efficient with the “Siemens-Martin Open Furnace” Method, making the price of steel low enough to allow entire buildings to be framed with steel members (price of steel per ton: 1865- $166; 1870- $107; 1875- $69; 1880- $68; 1885- $29; 1890- $32; 1895- $32) 1876: The “electromagnetic telephone” is invented by Alexander Graham Bell and begun to used. 1878: The electric light bulb is invented by Thomas A. Edison and begins to be used. 1879: The safety “elevator” (invented by Elisha Otis in 1854) used for the first time in a building in New York
Chicago School / “Commercial Style” Chicago Construction / Fire Proof Iron skeleton: The architects of Chicago school employed a new type of construction. The Floating Foundation: They invented a new kind of foundation to cope with the problem of the muddy ground of Chicago. The Chicago Window: They introduced the horizontaly elongated and “bay” window. They created the modern business and administration building typology. “Most importantly, for the first time in the nineteenth century the schism between construction and architecture, between the engineer and the architect, was healed. With surprising boldness, the Chicago school strove to break through to pure forms, forms which would unite construction and architecture in an identical expression.” Sigfried Giedion

What are the differences between the urbanization processes of Paris and Chicago in the 19th century?
Patronage Chief concerns Demolishment processes Urban layout Building types
At the end of this lecture you are expected to have learnt: 1.The implications of modernization at the urban level. 2.Differences between modern urbanization processes (The garden city, Paris, Chicago)
