Incorporation as Chesterfield The name "Chesterfield" was given by landowner Justus Post who arrived in Missouri in 1815 and began amassing an estate in the location of the present-day city. Post had grown up in Vermont, not far from the town of Chesterfield, New Hampshire, which sits on the border between New Hampshire and Vermont. Although Post eventually left Missouri and moved to Illinois, his chosen placename of "Chesterfield" stuck.
