George Adams II (1750-1795) was the son of George Adams I (1704-1772). They both worked at Tycho Brahe's Head, Fleet Street, moving to 60 Fleet Street. Both were mathematical instrument makers to George III and George Adams II was also optician to the Prince of Wales, later George IV and was succeeded by his younger brother Dudley in both the business and the appointments. In 1790, George Adams II published an essay entitled A Short Dissertation on the Barometer, Thermometer, and other Meteorological Instruments (N. Goodison, English Barometers, 1660-1860, Woodbridge, rev. ed., 1977, pp. 126 -127).
A related barometer by George Adams II was sold anonymously, Christie's London, 12 November 1998, lot 111.
