Dollond

John Dollond (1706–1761), a Huguenot silk weaver who lived and worked in the Spitalfields section of London, went into business with his son Peter in 1752, trading as J. Dollond & Son, and making and selling optical instruments. Dollond’s work with achromatic lenses led to a patent on April 19, 1758, the Copley Medal of the Royal Society later that year, and Royal Society fellowship in 1761. The firm remained in family hands until 1871, run by Peter Dollond (1761–1766), P. & J. Dollond (1766–1805), P. & G. Dollond (1805–1820), George Dollond (1820–1852), George Dollond the second (1852–1866), and William Dollond (1866–1871). Dollond and Aitchison, Ltd., formed in 1927, is still in business.
