Prior Scientific Instruments Ltd was established in London in 1919 as a manufacturer of optical microscopes, today it is a manufacturer of automated optical equipment. It is the last traditional microscope manufacturer and has survived from the one thriving British Microscope Industry serviced by well known manufacturers such as Vickers, W.Watson and Son, Baker, Charles Perry, Cooke, Troughton & Simms and many others who have ceased to produce microscopes.

Early History

W.R.Prior & Co.Ltd. was founded by W.R.Prior in 1919. Many records and a collection microscopes from the early  days of the Company were lost in a fire in 1988 but some illustrated catalogues have survived which give an indication of the range of quality instruments produced by W.R.Prior over the years for the highly competitive market of the time.

W.R.Prior & Co.Ltd offices were originally located at 9,10,11 Eagle Street, Holborn, London and later at 28a Devonshire Street, London  W.1. Little is known about the Company during at this time and no records or catalogues exist as to when and why they began to produce microscopes under Prior name.

A W.R.Prior  catalogue of Microscopes and Accessories dated February 1950 gives the location of the office as Devonshire Street and the factory as Bishop’s Stortford, Herts. England.(13 Northgate End) where manufacturing was carried out from 1942-1957).

War Time

The Eagle Street factory was destroyed during the London Blitz and the Company relocated to 13 Northgate End,Bishop Stortford.Herts. The building occupied was a garage and work commenced producing  optical gun sights, tank periscopes, and range finders for the Ministry of Defence. No microscopes were produced during the war.

The first post war abridged catalogue includes a wood block illustration of a student “C” limb microscope with the limb engraved with the Eagle Street address.

Post War

In 1947 Walter Robert Prior died at the early age of 55.

1953 brought the start of manufacturing micromanipulators for Prior and later the micropositioner was developed. Both of these are still made to this day.

The Company relocated to a new factory at London Road, Bishop Stortford in 1956 and continued to produce and develop new microscopes. Because of the need for new universities and colleges during the post war period there was a demand for microscopes and accessories and Prior was innovative in developing instruments for this market while maintaining the pre-war quality and finish. The Science Master Microscope, introduced in 1957, was in great demand for use in schools. The established Prior Monocular Dissecting Microscope was widely supplied  for educational use. The robustness and simplicity of these instruments gave many years of trouble free use.

For the Imperial Cancer Research Fund in London 1962, Prior supplied a Modular Inverted Microscope housed in a temperature controlled cabine for cell culture examination. The provision of  cine camera  enabled  continuous or time lapse cine-photography to be carried out.The Cinemicroscope was also adaptable for still photography or closed circuit television. The cabinet was m This microscope was certainly in advance of its time and one of the fore-runners of the modern inverted microscope-now such an essential tool in cell biology and tissue culture work. A unique Prior Tissue Culture Chamber was also supplied and enabled work to be carried out when using an inverted or standard erect microscope.

1970 - Present Day

In 1978 W.R.Prior & Co.Ltd. was acquired by The Gwyndann Group of Companies who are present owners 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. James Swift & Son was founded in 1854 and had an international reputation for producing advanced student and research polarising microscopes.The unique Swift Point Counter complimented the polarising microscope range and was sold worldwide. The James Swift  factory was initially at Basingstoke, Hants. this was closed after a year and the Company joined Prior Scientifc Instruments at London Road, Bishop’s Stortford.

In 1981 Prior launched a new modular series of stereomicroscopes-the S2000 series. The intention was that this instrument would replace and upgrade the Stereomaster microscope. The design had been based on that of an operating microscope featuring a long working distance it also had a tumbler rotating magnification system and a common objective. The design was a complete deviation from that of the previous Prior Greenough type microscope.

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 Rockland near Boston USA, in 2008 Prior GMBH in Jena, Germany, in 2010 Prior KK in Tokyo, Japan and in 2018 Prior China in Suzhou China.

The company continues to manufacture in the UK and has renewed emphasis on OEM projects, the company looks forward to celebrating its 100 year anniversary in 2019.
