Peter Dolland

Biography Dollond was born in Kensington. Working together with his father and subsequently with his younger brother and nephew (George Dollond) he successfully designed and manufactured a number of optical instruments. He is particularly credited with the invention of the triple achromatic lens - i.e., apochromatic lens - in 1763, still in wide use today, though known as the Cooke triplet after a much later 1893 patent.

Peter Dollond worked at first silk weaving with his father, but his father's passion for optics inspired him so much that in 1750 Peter quit the silk business and opened an optical instruments shop in Kennington, London. After two years, his father gave up silk, too, and joined him.

Dollond telescopes, for sidereal or terrestrial use, were amongst the most popular in both Great Britain and abroad for a period of over one and half centuries. Admiral Lord Nelson himself owned one. Another had sailed with Captain Cook in 1769 to observe the Transit of Venus. He was elected to the American Philosophical Society in 1772.

The Peter Dollond compound chest microscope is based on improvements to the Cuff-style microscope introduced by British scientific instrument designers Edward Nairne and Thomas Blunt around 1780. Another design was for the Peter Dollond compound monocular Eriometer around 1790 used to accurately measure the thickness and size of wool fibres.

After successfully defending a legal challenge to the patent he held for the achromatic lens the business prospered and he successfully sued his rivals for patent infringement. This privilege permitted Dollond to maintain an edge in quality over competitor's telescopes and optical instruments for many years.
