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]
