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.

After two years, his father gave up silk, too, and joined him. Dollond telescopes, for sidereal or terrestrial use, were amongst the most ...
