Description: | Wheatstone Bridge G.P.O. Model.
As well as inventing the English concertina, Sir Charles Wheatstone was responsible for many of the scientific breakthroughs of the Victorian era, including telegraphy, the stereoscope and most importantly his development of the Wheatstone bridge ? although he attributed Samuel Hunter Christie with its original invention. The Wheatstone Bridge was used to measure the electrical resistance of a conductor and was still in use until the advent of electronic measuring devices in the late 20th century. This example was made in London for the G.P.O. by H.W. Sullivan Ltd., of Great Winchester Street, in the first half of the 20th century. Interestingly, keys and levers like those used in his concertinas often appear in Wheatstone's scientific inventions. | License: | http://creativecommons.org/licenses/by-nc-sa/2.5/ | Publisher: | Horniman Museum and Gardens | Rights holder: | Horniman Museum, London | Subjects: | work | Temporal: | after 1922 | Source: | Horniman Museum | Identifier: | http://www.20thcenturylondon.org.uk/rser... | Go to resource |
