Made by Negretti and Zambra. The company was formed in 1850 between Henry Negretti and Joseph Warren Zambra who gained a patent in 1851 for the manufacture of thermometers. The firm continued to make an enormous number of meteorological instruments, thermometers, barometers, pressure gauges, optical and scientific instruments. Having originally started with a photographic studio, they were the official photographers for the Crystal Palace Exhibition 1853, they went on to sponsor Francis Frith* on expeditions to Egypt, Nubia and Ethiopia. Negretti and Zambra were the only English instrument makers to receive a prize medal for meteorological instruments at the 1851 Great Exhibition. They were appointed instrument makers to the Queen, Greenwich observatory, and the British Meteorological Society. *Francis Frith (1822-1898) Quaker, born in Liverpool, was a photographer and business man. He founded the Liverpool Photographic Society and only 15 years after the invention of the medium made "three he made three pioneering and sometimes dangerous photographic expeditions to the Middle East, taking bulky cameras, equipment and glass plates with him and travelling by boat, donkey, mule and camel. These journeys took him to Egypt, Nubia, Ethiopia, Sinai, Palestine, Lebanon and Syria, and established his reputation as an outstanding pioneer photographer." His photographs were sold through Negretti and Zamba. (Ref: Francis Frith's early career and expeditions to the Middle East - the Francis Frith Co.)Category
