The town of Chester was chartered as Murrayfield in 1765, and incorporated as Chester in 1783.

Emery was discovered in Chester by Dr. H.S. Lucas in 1856, though he thought what he had found was magnetite. Attempts were made to smelt the mineral into iron failed. In 1864, professor Charles T. Jackson of Boston examined mineral specimens from the mine and determined the material was actually emery (a mixture of magnetite and corundum), and thus a 100 year abrasive industry was born in Chester.
