Point du Sable is first recorded as living at the mouth of the Chicago River in a trader's journal of early 1790. By then he had established an extensive and prosperous trading settlement in what later became the City of Chicago. He sold his Chicago River property in 1800 and moved to the port of St. Charles, where he was licensed to run a ferry across the Missouri River. Point duSable's successful role in developing the Chicago River settlement was little recognized until the mid-20th century.
