Edward Davy
Edward Davy (16 June 1806 – 26 January 1885) was an English physician, scientist, and inventor who played a prominent role in the development of telegraphy, and invented an electric relay. Davy was born in Ottery St Mary, Devonshire, England, son of Thomas Davy (medical practitioner and house surgeon at Guy's Hospital, London). Edward Davy was educated at a school run by his maternal uncle in Tower Street, London. He was then apprenticed to Dr C. Wheeler, house surgeon at St Bartholomew's Hospital. Davy won the prize for botany in 1825, was licensed by the Worshipful Society of Apothecaries in 1828 and the Royal College of Surgeons in 1829. Soon after graduating, Davy began trading as an operative chemist under the name of Davy & Co. In 1836 he published a small book ''Experimental Guide to Chemistry'', at the end of which was a catalogue of goods supplied by his firm. Davy is distantly related to Humphry Davy. Davy published ''Outline of a New Plan of Telegraphic Communicati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

William Fothergill Cooke
Sir William Fothergill Cooke (4 May 1806 – 25 June 1879) was an English inventor. He was, with Charles Wheatstone, the co-inventor of the Cooke-Wheatstone electrical telegraph, which was patented in May 1837. Together with John Ricardo he founded the Electric Telegraph Company, the world's first public telegraph company, in 1846. He was knighted in 1869. Life He was born at Ealing, Middlesex; his father, William Cooke, was a surgeon there, and later was appointed professor of anatomy at the University of Durham. He was educated at Durham School and at the University of Edinburgh, and at the age of 20 entered the Indian Army. After five years' service in India Cooke returned home; then studied medicine in Paris, and at Heidelberg under Georg Wilhelm Munke. In 1836 he saw electric telegraphy, then only experimental: Munke had illustrated his lectures with a telegraphic apparatus on the principle introduced by Pavel Schilling in 1835. Cooke decided to put the invention into pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

19th-century British Inventors
The 19th (nineteenth) century began on 1 January 1801 ( MDCCCI), and ended on 31 December 1900 ( MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanding beyond its British homeland for the first time during this century, particularly remaking the economies and societies of the Low Countries, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost all of Africa under colonial rule.

People From Ottery St Mary
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

Electric Telegraph Company
The Electric Telegraph Company (ETC) was a British telegraph company founded in 1846 by William Fothergill Cooke and John Ricardo. It was the world's first public telegraph company. The equipment used was the Cooke and Wheatstone telegraph, an electrical telegraph developed a few years earlier in collaboration with Charles Wheatstone. The system had been taken up by several railway companies for signalling purposes, but in forming the company Cooke intended to open up the technology to the public at large. The ETC had a monopoly of electrical telegraphy until the formation of the Magnetic Telegraph Company (commonly called the ''Magnetic'') who used a different system which did not infringe the ETC's patents. The Magnetic became the chief rival of the ETC and the two of them dominated the market even after further companies entered the field. The ETC was heavily involved in laying submarine telegraph cables, including lines to the Netherlands, Ireland, the Channel Islands ...

Relay
A relay Electromechanical relay schematic showing a control coil, four pairs of normally open and one pair of normally closed contacts An automotive-style miniature relay with the dust cover taken off A relay is an electrically operated switch. It consists of a set of input terminals for a single or multiple control signals, and a set of operating contact terminals. The switch may have any number of contacts in multiple contact forms, such as make contacts, break contacts, or combinations thereof. Relays are used where it is necessary to control a circuit by an independent low-power signal, or where several circuits must be controlled by one signal. Relays were first used in long-distance telegraph circuits as signal repeaters: they refresh the signal coming in from one circuit by transmitting it on another circuit. Relays were used extensively in telephone exchanges and early computers to perform logical operations. The traditional form of a relay uses an electromagnet to c ...

Cooke And Wheatstone Telegraph
The Cooke and Wheatstone telegraph was an early electrical telegraph system dating from the 1830s invented by English inventor William Fothergill Cooke and English scientist Charles Wheatstone. It was a form of needle telegraph, and the first telegraph system to be put into commercial service. The receiver consisted of a number of needles which could be moved by electromagnetic coils to point to letters on a board. This feature was liked by early users who were unwilling to learn codes, and employers who did not want to invest in staff training. In later systems the letter board was dispensed with, and the code was read directly from the movement of the needles. This came about because the number of needles was reduced, leading to more complex codes. The change was motivated by the economic need to reduce the number of telegraph wires used, which was related to the number of needles. The change became more urgent as the insulation of some of the early installations deteriorat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Wheatstone
Sir Charles Wheatstone FRS FRSE DCL LLD (6 February 1802 – 19 October 1875), was an English scientist and inventor of many scientific breakthroughs of the Victorian era, including the English concertina, the stereoscope (a device for displaying three-dimensional images), and the Playfair cipher (an encryption technique). However, Wheatstone is best known for his contributions in the development of the Wheatstone bridge, originally invented by Samuel Hunter Christie, which is used to measure an unknown electrical resistance, and as a major figure in the development of telegraphy. Life Charles Wheatstone was born in Barnwood, Gloucestershire. His father, W. Wheatstone, was a music-seller in the town, who moved to 128 Pall Mall, London, four years later, becoming a teacher of the flute. Charles, the second son, went to a village school, near Gloucester, and afterwards to several institutions in London. One of them was in Kennington, and kept by a Mrs. Castlemaine, who ...
