A Trading Center
Incorporated as a city in 1837, Chicago was ideally situated to take advantage of the trading possibilities created by the nation’s westward expansion. The completion of the Illinois & Michigan Canal in 1848 created a water link between the Great Lakes and the Mississippi River, but the canal was soon rendered obsolete by railroads. Today, 50 percent of U.S. rail freight continues to pass through Chicago, even as the city has become the nation’s busiest aviation center, thanks to O’Hare and Midway International airports.
The Great Fire of 1871
As Chicago grew, its residents took heroic measures to keep pace. In the 1850s, they raised many of the streets five to eight feet to install a sewer system – and then raised the buildings, as well. Unfortunately, the buildings, streets and sidewalks were made of wood, and most of them burned to the ground in the Great Chicago Fire of 1871. The Chicago Fire Department training academy at 558 W. DeKoven St. is on the site of the O’Leary property where the fire began. The Chicago Water Tower and Pumping Station at Michigan and Chicago avenues are among the few buildings to have survived the fire.
