The De Saible, or du Sable, Cabin
Near Old Fort Dearborn you can see a reproduction of the cabin of Chicago's first citizen,
Jean Baptiste Point de Saible, who lived on teh north bank of the Chicago River, and
traded in furs, even before the fort was built. He was a prosperous, educated negro of
French extraction. The cabin gave way to what then was considered a mansion, and in it he
collected Chicago's first art collection and library. It is thought he established his
first cabin in 1777 and left in 1800, to go further south than Illinois.
