Chesterfield was first settled in 1760 and was officially incorporated in 1762. It was named after the Earl of Chesterfield.[3] The town center, established after the Revolution, has well-preserved Federal period houses along Main Road. In its early days, the town supported a largely agricultural economy, with wool from Merino sheep as a major product. However, there were sawmills and tanneries in operation as well as cloth dressing mills, and in the early 19th century these superseded farming and brought in a small immigrant population that was mostly Irish. Progress wiped out most of the industry in Chesterfield, and by the start of the 20th century a re-emerging agricultural economy developed alongside the growing trade from summer residents.
