Jacques Clamorgan was an adventurer, fur trader and land owner in the United States.
He laid claim to more than 1 million acres of Upper Louisiana land, granted by the Spanish authorities.
The US government after de Louisiana Purchase offered $8 million (In 2011 $US) in response to Clamorgan's Spanish titles of property.
In a tax-evasion effort, Clamorgan set his slave concubine free in order to give her some of his land holdings.
Ester, the freed slave, sued Clamorgan for rightful ownership of this land when he demanded it back.
