A half breed from Santo Domingo, Jean Baptiste Point De Sable, became the founder of Chicago, where he lived just before the American Revolution. His life as a pioneering fur trader who came to Louisiana in 1764 and headed up the Mississippi to become the friend of Great Lakes Indians, has been little studied and recognized. Here a sensitive biographer follows his deeds in clean historical perspective. Born on Santo Domingo as the son of a French sailor and a Negro, Jean Baptiste was sent to school in France when he was eleven. A decade later he sailed for the new world. From New Orleans, where he was a victim of race prejudice, he trekked north to St. Louis and on to Lake Michigan, befriending on the way the great chief Pontiac and later marrying into the Potawatomie tribe and settling with them at their place- Eschikagou. There he established the first makings of a city, and stayed to see his children settled before he returned to St. Louis. Force of narrative pays tribute to a diligent founder who should be more widely known than he is.
