WR Prior & Co Ltd was founded by Walter Robert Prior in 1919. The company was originally located at Eagle Street, Holborn, London and later at Devonshire Street, London. Little is known about the Company during this time and no records or catalogues exist as to when and why they began to produce microscopes under the Prior name. A WR Prior catalogue of microscopes and accessories dated 1950 gives the location of the office as Devonshire Street and the factory as Bishop’s Stortford, Herts., England, where manufacturing was carried out from 1942 to 1957. On 10 January 1947 Walter Robert Prior died at the early age of 55. The company relocated to a new factory at London Road, Bishop Stortford in 1956 and continued to produce and develop new microscopes. By 1960, Prior and Charles Perry merged together but kept their separate names until about 1970. In 1978 WR Prior & Co Ltd was acquired by The Gwyndann Group of Companies and the name of the company was changed in 1979 to that of Prior Scientific Instruments Ltd. In 1981 Prior Scientific Instruments Ltd merged with James Swift and Son Ltd (founded in the mid 19th century). Fire at the Bishop Stortford factory in 1988 meant the company had to relocate to its present site in Fulbourn, Cambridge, England, offering precision mechanical engineering, optics, electronics and precision assembly. Expanding its operation further the company opened a new office in 1991, Prior Scientific Inc, based in the USA, in 2008 Prior GMBH in Jena, Germany, in 2010 Prior KK in Tokyo, Japan and in 2018 Prior China. Microscope 59 was produced by WR Prior and dates from 1936. It is signed ´WR Prior & Co, 9 – 11 Eagle St, London’ and has the serial number 6465 engraved on the tube. The microscope came with a wooden box including a guarantee signed by Walter Robert Prior himself, with the date ‘October 1936’ and the indication of the microscope number as 6465.
