Naval range-finding instruments of 1936

Barr & Stroud Limited was a pioneering Scottish optical engineering firm, based in Glasgow, that played a leading role in the development of modern optics, including rangefinders, for the Royal Navy and for other branches of British Armed Forces during the 20th century. There was a non-military arm of the company which made medical equipment, like photocoagulators and electronic filters, some of which were used by the BBC. The company and its intellectual property passed through Pilkington group to Thales Optronics. The Barr and Stroud name was sold on to an importer of optical equipment who use the trademarked name.

Barr and Stroud was founded by Archibald Barr and William Stroud[1] as a limited company in 1913, but they began development work as early as 1888. Barr and Stroud rangefinders were sold world wide and were used almost universally in the Royal Navy during World War II. Barr & Stroud also produced fire control instruments and a range of commercial products, such as binoculars.

History[edit | edit source]

The original Barr & Stroud company was founded in 1913. Archibald Barr and William Stroud had been associated from as early as 1888 when the two men were professors of, respectively, engineering and physics at the Yorkshire College (now the University of Leeds). In 1891 they were approached by the Admiralty to submit a design for a short-base rangefinder for trial. By this time, Barr had returned to Scotland and taken the post of Regius Professor of Civil Engineering and Mechanics at the University of Glasgow. Although now apart Barr and Stroud kept in close touch and in 1892 they were awarded with a contract for six of their rangefinders.

In 1895, Barr & Stroud's Patents Ltd was renting workshop space near the university, at 250 Byres Road, Glasgow, but demand for the product soon necessitated a move to larger premises in Ashton Lane, Glasgow. By 1904, 100 men were working for the company in a new purpose-built factory in Anniesland, Glasgow. Shortly thereafter, in 1909, Stroud resigned his chair at University of Leeds and moved to Glasgow to work for the company full-time. Barr, in spite of a distinguished teaching career at Glasgow University, followed his example in 1913. Together they formed Barr & Stroud Ltd.

In 1914 they began extensions to the Anniesland works in order to meet the sharp increase in demand for their rangefinders that followed on the outbreak of the First World War. The war years saw the development of other products, including a torpedo depth recorder, a periscope rangefinder, fire-control systems and a dome sight for aircraft. During World War I there was a problem with the supply of binoculars to the armed forces and apart from the British makers, binoculars were bought in from various sources. So it was only natural that the military would be looking to rectify this problem. At the time Zeiss was probably the leading makers and the military thought this may cause a problem in the future.

It was c.1919 when the company started producing their first binoculars which were supplied to the British Navy and from then on the company continued to operate independently until c.1977 when they were taken over by the Pilkington Group. In 1992 operations moved from the original factory in Anniesland to a new plant in Linthouse on the site of the former Alexander Stephen and Sons shipyard. In 2000 the company became a subsidiary of the French company, Thales Group, and in 2001 Barr & Stroud Ltd became Thales Optronics Ltd.

The Barr and Stroud brand name was then bought by Eastleigh-based Optical Distribution Services Ltd who re-registered as Barr and Stroud Ltd in 2008. The new company has developed a new range of binoculars and telescopes. The new range of Barr & Stroud binoculars are currently made in China (Nov. 2011) and distributed by Optical Vision Ltd.
