===British Sperry===
Sperry in Britain started with a factory in [[Pimlico]], London, in 1913, manufacturing gyroscopic compasses for the
[[Royal Navy]]. It became the Sperry Gyroscope Co Ltd in 1915. In 1923, [[Lawrence Sperry]] was killed in an air crash near [[Rye, East Sussex|Rye, Sussex]]. The company subsequently expanded to the [[Golden Mile (Brentford)|Golden Mile]], [[Brentford]] in 1931, [[Stonehouse, Gloucestershire|Stonehouse]], Gloucestershire<ref name="flight63">{{cite web |title=Fifty Years of British Sperry|work=Flight International |date=March 28, 1963|page=434|url=http://www.flightglobal.com/pdfarchive/view/1963/1963%20-%200456.html}}</ref> in 1938, and [[Bracknell]] in 1957.<ref>{{cite web |title=Sperry Gyroscope Company (Bracknell)|work=[[Hansard|Parliamentary Debates (Hansard)]]|date=April 29, 1966|url=https://api.parliament.uk/historic-hansard/commons/1966/apr/29/sperry-gyroscope-company-bracknell}}</ref> By 1963, these sites employed some 3,500 people.<ref name="flight63" /> The Brentford site closed in 1967, with the expansion of Bracknell.

The site of the Bracknell factory and development center (sold to [[British Aerospace]] in 1982) is commemorated by a 4.5-meter aluminum sculpture by [[Philip Bentham]], ''Sperry's New Symbolic Gyroscope'' (1967).<ref>{{cite web|title=Sperry's New Symbolic Gyroscope|publisher=Bracknell Forest Borough Council|url=http://www.bracknell-forest.gov.uk/sperrys-new-symbolic-gyroscope.pdf|url-status=dead|archive-url=https://web.archive.org/web/20110927022440/http://www.bracknell-forest.gov.uk/sperrys-new-symbolic-gyroscope.pdf|archive-date=September 27, 2011}}</ref>

In 1989, the Bracknell site was downsized and work was moved to the Sperry manufacturing site in [[Plymouth]] by then under the [[British Aerospace]] brand. State of the art, high technology [[MEMS]] gyroscopes (together with other avionics equipment) are still made on the site today, although the company is now owned by [[United Technologies Corporation]] and is part of [[UTC Aerospace Systems]].
