Dollond was a UK-based optical and mathematical instrument company, founded in 1750 in London by John Dollond (1706-1761) and his son Peter (1730-1820). John Dollond invented one of the first achromatic lenses - patented in 1758 (if not The First, although optician George Bass seems to have made achromats, perhaps from 1729[1]). This lens was used for the first achromatic telescope; the Dollonds went on to make several more inventions in achromatic lenses, telescopes and heliometers. Peter's nephew George Dollond (1774-1852) took over the company in 1819.
Dollond's had sold Cameras Lucidae and Cameras Obscurae in the 18th and 19th Century, and sold film cameras in the early 20th.
