Add article description

Chester Moore Hall (9 December 1703, Leigh, Essex, England – 17 March 1771, Sutton) was a British lawyer and inventor who produced the first achromatic lenses in 1729 or 1733 (accounts differ). He used the achromatic lens to build the first achromatic telescope, a refracting telescope free from chromatic aberration (colour distortion).[1]

He lived at New Hall, Sutton.

His name was also spelled Chester Moor Hall[2][3] and Chester More Hall.[4]

The design had two elements, a crown and flint glass, that brought two wavelengths of light to a focus.[5]

Chester is noted as having made the first twin color corrected lens in 1730.[6]
