- **1871** — The Great Chicago Fire destroys 3.3 square miles — 300+ deaths, 100,000 homeless — leads to the world's first skyscraper boom
- **1885** — Home Insurance Building completed — widely considered the world's first skyscraper (10 stories, steel frame)
- **1893** — World's Columbian Exposition — the "White City" showcases American innovation and births the City Beautiful movement

- **Education**: University of Chicago, Northwestern (nearby), Loyola, DePaul

## Interesting Facts
- Chicago literally reversed the flow of its river — in 1900, engineers built a canal system that made the Chicago River flow backward (away from Lake Michigan, its water supply, toward the Mississippi) to prevent sewage from contaminating the city's drinking water. It remains one of the greatest engineering feats in history
- The Great Chicago Fire of 1871 was blamed on a cow kicking over a lantern (the famous Mrs. O'Leary's cow myth) — in reality, the cause was never determined, and a simultaneous fire in Peshtigo, Wisconsin, killed far more people (1,500+) on the same night
