The Name First Appears
French Jesuit Pierre Charlevoix wrote the word "Chicagou" in his report. The name came from the wild onions that grew thick along the marshy riverbanks. Their smell lingered in the air long after the plants were crushed underfoot. This small linguistic marker would eventually label one of the most ambitious cities ever built.

DuSable Builds the First House
Jean Baptiste Point DuSable, a Black trader from Haiti, erected a cabin on the north bank of the Chicago River. He ran a trading post, married a Potawatomi woman, and lived among both Indigenous people and Europeans. The settlement smelled of smoked fish and cured hides. Historians now credit him as Chicago's first permanent resident.

The Town of Chicago Is Born
With 350 residents the settlement officially incorporated as a town. The Potawatomi had just signed away millions of acres in the Treaty of Chicago. Wooden shacks replaced bark lodges almost overnight. The smell of fresh-cut pine mixed with the river's onion stink.

Wright Perfects Prairie Style
Frank Lloyd Wright completed the Robie House in Hyde Park. Its long horizontal lines hugged the flat Midwestern land like nothing before it. Inside, light poured through art glass windows onto open floor plans. The house still feels radical more than a century later.

The 1,450-foot Sears Tower opened in the Loop. For nearly 25 years it was the tallest building on Earth. Office workers on upper floors sometimes felt the structure sway in high winds. Tourists now pay to stand on The Ledge, a glass box jutting out 1,353 feet above South Wacker Drive.
