 John Hart Crenshaw was a large landowner, salt maker, and slave trader, from the 1820s to the 1850s, based out of the southeastern part of Illinois in Gallatin County and a business associate of Kentucky lawman and outlaw, James Ford.Crenshaw and Ford were allegedly kidnapping free blacks in southeastern Illinois and selling them in the slave state of Kentucky.Although Illinois was a free state, Crenshaw leased the salt works in nearby Equality, Illinois from the U.S. Government, which permitted the use of slaves for the arduous labor of hauling and boiling salt brine water from local salt springs to produce salt.
