Founded in 1850 firm Negretti and Zambra was a photographic studio and producer of optical and scientific instruments based in London. Henry Negretti and Joseph Zambra were appointed optical instrument makers to Prince Albert, the Royal Observatory and the British Admiralty. Negretti and Zambra remained in family hands and played a major role in Britain’s war effort in the First and Second World Wars. Their work with the Ministry of Munitions between 1914-18 saw significant innovation in the field of early aviation instruments. Following the conflict, the decision was taken to focus much of the company’s output on projects for the Air Ministry. Consequently, at the outbreak of hostilities in 1939, Negretti and Zambra’s works were relocated to the relative safety of Chesterfield. Here they manufactured thermometers and boost gauges for the iconic Spitfire and Hurricane fighters, as well as the Lancaster bomber.
