Chester Moore Hall
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]
